SCOPE
1.1 This test method is used to determine the arc rating of hand protective products in the form of gloves, glove materials, glove material systems, or other protective products designed to fit on the hand and specifically intended for electric arc flash protection use as protective accessories for workers exposed to electric arcs. The arc rating is determined in the test with an arc that has a heat flux value of 2100 kW/m2 [50 cal/cm2/s].  
1.2 This test method will determine the arc rating of hand protective products made of materials that meet the following requirements for flame resistance: less than 150 mm [6 in.] char length, less than 2 s afterflame and no melt and drip when tested in accordance with Test Method D6413, receive a reported 50 % probability of ignition of a material or flammable underlayer (see definition of ignition50) by this method, or that have been evaluated and pass the ignition withstand requirements of this test method.  
1.2.1 It is the intent of this test method to be used for hand protective products that are flame resistant or that have an adequate flame resistance for the required hazard (see 1.2). Non-flame resistant hand protective products may be used as under layers in multiple-layer systems or tested for ignition probability or ignition withstand.  
1.2.2 Hand protective products tested by this test method are new and ratings received by this method may be reduced or eliminated by hydrocarbon loading (gasoline, diesel fuel, transformer oil, etc.), sweat, dirt, grease, or other contaminants. The end user takes responsibility for use of hand protective products tested by this method when contaminated in such a manner that could reduce or eliminate the arc rating of the hand protective products.

SCOPE
1.1 This product specification is used to determine the ability of the arc protective blankets to withstand the effects of arc flash and arc blast in a configuration in which the blanket is hung or anchored near energized equipment. Specifically, the imbedded test method is used to determine and specify the arc protective blanket’s (1) resistance to breakopen, (2) mechanical strength, and (3) ability to self-extinguish flames following a controlled arc exposure.  
1.2 The products covered by this specification are labeled with a performance level for arc protective blankets in terms of: maximum arc current level expressed in kA and Breakopen Threshold Performance (BTP) expressed as the product of arc current in kA and arc duration in number of cycles to cause breakopen (kA*cycles). Cycles are on the basis of 60 Hz.  
1.3 Blanket test specimens used in this specification are test size blankets of 152 ± 5 cm [60 ± 2 in.] by 122 ± 5 cm [48 ± 2 in.]. The test specimen size is for testing purposes only. Commercially available arc protective blankets either larger or smaller than the test specimen size are covered by this specification.  
1.4 The arc protective blankets described in this specification are made of flame-resistant materials and are available in varying sizes and configurations based on the application.  
1.5 The specification is used to measure and describe the properties of materials, products, or assemblies in response to incident thermal (convective and radiant) and pressure energies generated by an electric arc under controlled laboratory conditions.  
1.6 The values stated in SI units shall be regarded as standard except as noted. The values stated in each system may not be exact equivalents; therefore, alternate systems must be used independently of the other. Combining values from the systems described in the text may result in nonconformance with the method.  
1.7 This standard shall not be used to describe or appraise the fire hazard or fire risk of materials, products, or assemblies under actual fire conditions. However, results of this test may be used as elements of a fire assessment, which takes into account all of the factors, which are pertinent to an assessment of the fire hazard of a particular end use.  
1.8 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. For specific precautions, see Section 9.  
1.9 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

SIGNIFICANCE AND USE
5.1 This practice can be used for a range of purposes including incident replication, development of improved arc rated protective products, and the determination of the response characteristics and design integrity of new or used arc rated finished products intended for use as protection for workers exposed to electric arcs.  
5.1.1 In-service garments can have very different wash and wear histories. Caution must be used when applying test results from a particular used garment. Factors to consider include the garments’ wear histories, work environments, and tasks for which the garments were worn; the methods and facilities for garment maintenance; the number of launderings or processings the garments have been subjected to; and other factors that could impact the protective performance of different garments. Test results from specific used garments should be considered only an approximation of results that might be obtained from other used garments of the same type.  
5.1.2 When using the practice for evaluating flame resistance, great care should be taken since ignition by electric arc is a statistical phenomenon. An exposure of 20 cal/cm2 has been consistently shown to evaluate most ignitable materials but some may require higher energy to reach the breakopen point of the fabric depending on coatings or specific fiber types. Consider using a vertical flame test such as Test Method D6413 to evaluate for ignition and use this practice for illustration.  
5.2 This practice maintains the specimen in a static, vertical position and does not involve movement except that resulting from the exposure.
SCOPE
1.1 This practice identifies protocols for use in conducting arc testing on finished products intended for use as thermal protection by workers who may be exposed to electric arc hazards.  
1.1.1 The practice is also used for other components which can be exposed to electric arc, but which do not require an arc rating.
1.1.1.1 If items are tested and they do not meet the appropriate standard, it is the responsibility of the specimen submitter to provide this information for indication in the test report.  
1.2 Arc Rated protective items are typically tested using this practice to evaluate the performance of the interface area between the product and the other arc flash PPE or to evaluate zippers and other findings.  
1.3 This practice does not establish an arc rating for any product. Other ASTM test methods are to be used when applicable such as ASTM F1959/F1959M, F2178, and F2675.  
1.4 This practice is not intended to produce an arc rating and does not replicate in all types of arc exposures.  
1.5 This practice is used with the following standards:  
1.5.1 Protective fabric materials receive arc ratings from Test Method F1959/F1959M.  
1.5.2 Face protective products receive arc ratings from Test Method F2178.  
1.5.3 Gloves receive arc ratings from Test Method F2675.  
1.5.4 Rainwear materials, findings and closures are specified by Specification F1891.  
1.5.5 Garments are specified by Specification F1506.  
1.6 The test specimens used in this practice are typically in the form of arc-rated finished products. These arc-rated finished products may include, but are not limited to, single layer garments, multi-layer garments or ensembles, cooling vests, gloves, sleeves, chaps, rainwear, balaclavas, faceshields, and hood assemblies with hood shield windows. Non-arc rated finished products may be included when part of a flame-resistant system, or for evaluating heat transmission through the finished product for incident reenactment, or for evaluation of products needed but not available as arc rated (such as respirators, etc.)  
1.7 The arc rated finished product specimens are new products as sold or products which have been used for the intended purpose for a designated time.  
1.8 This practice is used to determine the response characteristics or design integrity of arc-ra...

SCOPE
1.1 This test method is used to determine the arc rating of hand protective products in the form of gloves, glove materials, glove material systems, or other protective products designed to fit on the hand and specifically intended for electric arc flash protection use as protective accessories for workers exposed to electric arcs. The arc rating is determined in the test with an arc that has a heat flux value of 2100 kW/m2 [50 cal/cm2/s].  
1.2 This test method will determine the arc rating of hand protective products made of materials that meet the following requirements for flame resistance: less than 150 mm [6 in.] char length, less than 2 s afterflame and no melt and drip when tested in accordance with Test Method D6413, receive a reported 50 % probability of ignition of a material or flammable underlayer (see definition of ignition50) by this method, or that have been evaluated and pass the ignition withstand requirements of this test method.  
1.2.1 It is the intent of this test method to be used for hand protective products that are flame resistant or that have an adequate flame resistance for the required hazard (see 1.2).

SIGNIFICANCE AND USE
5.1 This practice can be used for a range of purposes including incident replication, development of improved arc rated protective products, and the determination of the response characteristics and design integrity of new or used arc rated finished products intended for use as protection for workers exposed to electric arcs.  
5.1.1 In-service garments can have very different wash and wear histories. Caution must be used when applying test results from a particular used garment. Factors to consider include the garments’ wear histories, work environments, and tasks for which the garments were worn; the methods and facilities for garment maintenance; the number of launderings or processings the garments have been subjected to; and other factors that could impact the protective performance of different garments. Test results from specific used garments should be considered only an approximation of results that might be obtained from other used garments of the same type.  
5.1.2 When using the practice for evaluating flame resistance, great care should be taken since ignition by electric arc is a statistical phenomenon. An exposure of 20 cal/cm2 has been consistently shown to evaluate most ignitable materials but some may require higher energy to reach the breakopen point of the fabric depending on coatings or specific fiber types. Consider using a vertical flame test such as Test Method D6413 to evaluate for ignition and use this practice for illustration.  
5.2 This practice maintains the specimen in a static, vertical position and does not involve movement except that resulting from the exposure.
SCOPE
1.1 This practice identifies protocols for use in conducting arc testing on finished products intended for use as thermal protection by workers who may be exposed to electric arc hazards.  
1.1.1 The practice is also used for other components which can be exposed to electric arc, but which do not require an arc rating.
1.1.1.1 If items are tested and they do not meet the appropriate standard, it is the responsibility of the specimen submitter to provide this information for indication in the test report.  
1.2 Arc Rated protective items are typically tested using this practice to evaluate the performance of the interface area between the product and the other arc flash PPE or to evaluate zippers and other findings.  
1.3 When evaluating arc rated PPE with non-arc rated PPE for due diligence (such as respirators, etc.), this practice does not result in an arc rating for non-arc rated components or products shall be clearly indicated as having no arc rating.  
1.4 This practice is not intended to produce an arc rating and does not replicate in all types of arc exposures.  
1.5 This practice is used with the following standards:  
1.5.1 Protective fabric materials receive arc ratings from Test Method F1959/F1959M.  
1.5.2 Face protective products receive arc ratings from Test Method F2178.  
1.5.3 Gloves receive arc ratings from Test Method F2675.  
1.5.4 Rainwear materials, findings and closures are specified by Specification F1891.  
1.5.5 Garments are specified by Specification F1506.  
1.6 The test specimens used in this practice are typically in the form of arc-rated finished products. These arc-rated finished products may include, but are not limited to, single layer garments, multi-layer garments or ensembles, cooling vests, gloves, sleeves, chaps, rainwear, balaclavas, faceshields, and hood assemblies with hood shield windows. Non-arc rated finished products may be included when part of a flame-resistant system, or for evaluating heat transmission through the finished product for incident reenactment, or for evaluation of products needed but not available as arc rated (such as respirators, etc.)  
1.7 The arc rated finished product specimens are new products as sold or products which have been used for the intended purpose for a designated time.

SIGNIFICANCE AND USE
9.1 This specification’s test method is used to determine an arc rating for eye or face protective products, including face shields, safety spectacles, goggles, or other applicable portions of the complete product that are required to meet the current version of ANSI/ISEA Z87.1. This excludes the textile or parts of the hood assemblies or other rated products that are not testable by ANSI/ISEA Z87.1. This standard does not measure optical and impact properties (see ANSI/ISEA Z87.1) but does specify requirements for optical and impact properties in accordance with that standard.  
9.2 The test method is used to measure and describe the properties of materials, products, or assemblies in response to convective and radiant energy generated by an electric arc under controlled laboratory conditions and does not purport to predict damage from light other than the thermal aspects measured.  
9.3 The specification’s test method is intended for the determination of the arc rating of a product/design, intended for use as eye or face protection for workers exposed to electric arcs. For whole body protection, additional personal protective equipment (PPE) will be required for parts not covered by this standard.  
9.3.1 Because of the variability of the arc exposure, different heat transmission values may be observed at individual sensors. The results of each sensor are evaluated in accordance with Section 16.  
9.4 This test method maintains the specimen in a static, vertical position and does not involve movement except that resulting from the exposure.  
9.5 Different exposure conditions produce different incident energies and different heat fluxes. This standard exposure is used for comparison of products and hazard assessment methods may use multiplication factors or other means for determining protection.  
9.6 The purchaser has the option to perform or have performed any of these tests to verify the performance of the eye or face protective product. Claims for failu...
SCOPE
1.1 This product specification is used to determine the arc rating and specify the requirements for products intended for use as eye or face protection for workers exposed to electric arcs. The arc rating is determined in the test with an arc which has a heat flux value of 2100 kW/m2 [50 cal/cm2/s]. Products are tested as sold.  
1.2 The products covered by this standard are in the form of faceshields attached to the head by protective helmets (hard hats), headgear, hood assemblies, safety spectacles or goggles. Faceshields, safety spectacles or goggles are tested with or without other face and head protective products, for example, sock hoods, balaclavas, sweat shirt hoods or jacket hoods.  
1.2.1 Fabric layers used in the design of face protection products such as in hood, neck guards, balaclava, meet the requirements of Specification F1506. When fabrics are designed into the protection provided for eye or face protective products, the arc rating of fabric system is first determined by Test Method F1959/F1959M.  
1.2.2 The arc rating of the eye or face protective product which requires fabric to provide protection to the face or head will not be higher than the lower arc rating of either the fabric system or the shield/visor assembly.  
1.3 The values stated in SI units shall be regarded as standard except as noted. Within the text, alternate units are shown in brackets. The values stated in each system may not be exact equivalents; therefore, alternate systems must be used independently of the other. Combining values from the systems described in the text may result in nonconformance with the method.

SIGNIFICANCE AND USE
5.1 This practice can be used for a range of purposes including incident replication, development of improved arc rated protective products, and the determination of the response characteristics and design integrity of new or used arc rated finished products intended for use as protection for workers exposed to electric arcs.  
5.1.1 In-service garments can have very different wash and wear histories. Caution must be used when applying test results from a particular used garment. Factors to consider include the garments’ wear histories, work environments, and tasks for which the garments were worn; the methods and facilities for garment maintenance; the number of launderings or processings the garments have been subjected to; and other factors that could impact the protective performance of different garments. Test results from specific used garments should be considered only an approximation of results that might be obtained from other used garments of the same type.  
5.1.2 When using the practice for evaluating flame resistance, great care should be taken since ignition by electric arc is a statistical phenomenon. An exposure of 20 cal/cm2 has been consistently shown to evaluate most ignitable materials but some may require higher energy to reach the breakopen point of the fabric depending on coatings or specific fiber types. Consider using a vertical flame test such as Test Method D6413 to evaluate for ignition and use this practice for illustration.  
5.2 This practice maintains the specimen in a static, vertical position and does not involve movement except that resulting from the exposure.
SCOPE
1.1 This practice identifies protocols for use in conducting arc testing on finished products intended for use as thermal protection by workers who may be exposed to electric arc hazards.  
1.1.1 The practice is also used for other components which can be exposed to electric arc, but which do not require an arc rating.
1.1.1.1 If items are tested and they do not meet the appropriate standard, it is the responsibility of the specimen submitter to provide this information for indication in the test report.  
1.2 Arc Rated protective items are typically tested using this practice to evaluate the performance of the interface area between the product and the other arc flash PPE or to evaluate zippers and other findings.  
1.3 When evaluating arc rated PPE with non-arc rated PPE for due diligence (such as respirators, etc.), this practice does not result in an arc rating and non-arc rated components or products shall be clearly indicated as having no arc rating.  
1.4 This practice is not intended to produce an arc rating and does not replicate in all types of arc exposures.  
1.5 This practice is used with the following standards:  
1.5.1 Protective fabric materials receive arc ratings from Test Method F1959/F1959M.  
1.5.2 Face protective products receive arc ratings from Test Method F2178.  
1.5.3 Gloves receive arc ratings from Test Method F2675.  
1.5.4 Rainwear materials, findings and closures are specified by Specification F1891.  
1.5.5 Garments are specified by Specification F1506.  
1.6 The test specimens used in this practice are typically in the form of arc-rated finished products. These arc-rated finished products may include, but are not limited to, single layer garments, multi-layer garments or ensembles, cooling vests, gloves, sleeves, chaps, rainwear, balaclavas, faceshields, and hood assemblies with hood shield windows. Non-arc rated finished products may be included when part of a flame-resistant system, or for evaluating heat transmission through the finished product for incident reenactment, or for evaluation of products needed but not available as arc rated (such as respirators, etc.)  
1.7 The arc rated finished product specimens are new products as sold or products which have been used for the intended purpose for a designated time.  
1.8 This practice is ...

SIGNIFICANCE AND USE
5.1 This test method determines the effectiveness of arc protective blankets in suprressing the combined effects of an arc flash and arc blast.  
5.2 The arc exposure energy is produced from controlled phase-to-ground arc fault. The resulting arc flash and blast energy are intentionally directed onto the test specimen to simulate worst case conditions.  
5.3 Test results will describe the maximum arc current and product of arc current and cycles at which test specimens block the energy without breakopen, ability to self-extinguish afterflaming, afterflame time and the detection of mechanical attachment failures during testing. Mechanical attachment failure and afterflame time are obtained from visual observations and video recording after each arc exposure.  
5.4 This test method maintains the arc protective blanket in a vertical position and does not involve movement except that resulting from the arc exposure.  
5.5 In this test method, test specimens are exposed at three arc current levels to determine the test specimen’s performance.
Note 2: In experimental testing, some blankets increase in protection (in value of kA*cycles to cause breakopen) as the arc current increases and some decrease as shown in Fig. 1. This test method is designed to recognize this behavior and to specify testing over the range of arc current levels including lower levels of 5 kA or 10 kA, or both.  
FIG. 1 Example of Performance Trend for Different Blankets
5.6 This test method specifies a standard set of exposure conditions. Different exposure conditions may produce different results.
Note 3: In addition to the standard set of exposure conditions, it is permitted to test using other conditions representative of the expected hazard, reported all non-standard test conditions that are used.
SCOPE
1.1 This test method is used to evaluate the ability of the arc protective blankets to withstand the effects of arc flash and arc blast in a configuration in which the blanket is hung or anchored near energized equipment. Specifically, this test method is used to determine the arc protective blanket’s (1) resistance to breakopen, (2) mechanical strength, and (3) ability to self-extinguish flames following a controlled arc exposure.  
1.2 This method is used to determine the performance of arc protective blankets in terms of: maximum arc current level expressed in kA and BTP (BTP) expressed as the product of arc current in kA and arc duration in number of cycles to cause breakopen (kA*cycles). Cycles are on the basis of 60 Hz.  
1.3 Blanket test specimens used in this test method are test size blankets of 152 ± 5 cm (60 ± 2 in.) by 122 ± 5 cm (48 ± 2 in.). The test specimen size is for testing purposes only. Commercially available arc protective blankets either larger or smaller than the test specimen size are covered by this standard.  
1.4 The arc protective blankets described in this test method are made of flame-resistant materials and are available in varying sizes and configurations based on the application.  
1.5 This test method shall be used to measure and describe the properties of materials, products, or assemblies in response to incident thermal (convective and radiant) and pressure energies generated by an electric arc under controlled laboratory conditions.  
1.6 The values stated in SI units shall be regarded as standard. The values given in parentheses are mathematical conversion to inch-pound or other units commonly used for arc testing.  
1.7 This standard shall not be used to describe or appraise the fire hazard or fire risk of materials, products, or assemblies under actual fire conditions. However, results of this test may be used as elements of a fire assessment, which takes into account all of the factors, which are pertinent to an assessment of the fire hazard of a particular end use.

SIGNIFICANCE AND USE
5.1 This test method is intended for the determination of the arc rating of a hand protective product material, or a combination of hand protective product materials.  
5.1.1 Because of the variability of the arc exposure, different heat transmission values are observed at individual sensors. Evaluate the results of each sensor in accordance with Section 12.  
5.2 This test method maintains the specimen in a static, vertical position and does not involve movement except that resulting from the exposure.  
5.3 This test method specifies a standard set of exposure conditions. Different exposure conditions have the potential to produce different results. In addition to the standard set of exposure conditions, other conditions are allowed and shall be documented in the reporting of the testing results.
SCOPE
1.1 This test method is used to determine the arc rating of hand protective products in the form of gloves, glove materials, glove material systems, or other protective products designed to fit on the hand and specifically intended for electric arc flash protection use as protective accessories for workers exposed to electric arcs. The arc rating is determined in the test with an arc that has a heat flux value of 2100 kW/m2 [50 cal/cm2/s].  
1.2 This test method will determine the arc rating of hand protective products made of materials that meet the following requirements for flame resistance: less than 150 mm [6 in.] char length, less than 2 s afterflame and no melt and drip when tested in accordance with Test Method D6413, receive a reported 50 % probability of ignition of a material or flammable underlayer (see definition of ignition50) by this method, or that have been evaluated and pass the ignition withstand requirements of this test method.  
1.2.1 It is the intent of this test method to be used for hand protective products that are flame resistant or that have an adequate flame resistance for the required hazard (see 1.2). Non-flame resistant hand protective products may be used as under layers in multiple-layer systems or tested for ignition probability or ignition withstand.  
1.2.2 Hand protective products tested by this test method are new and ratings received by this method may be reduced or eliminated by hydrocarbon loading (gasoline, diesel fuel, transformer oil, etc.), sweat, dirt, grease, or other contaminants. The end user takes responsibility for use of hand protective products tested by this method when contaminated in such a manner that could reduce or eliminate the arc rating of the hand protective products.  
1.2.3 This test method is designed to provide information for gloves used for electric arc protection only. This test method is not suitable for determining electrical protective properties of hand protective products.  
1.3 This test method is used to measure and describe the properties of hand protective products in response to convective and radiant energy generated by an electric arc under controlled laboratory conditions.  
1.4 This test method does not apply to electrical contact or electrical shock hazards.  
1.5 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system are not necessarily exact equivalents; therefore, to ensure conformance with the standard, each system shall be used independently of the other, and values from the two systems shall not be combined  
1.6 This standard shall not be used to describe or appraise the fire hazard or fire risk of materials, products, or assemblies under actual fire conditions. However, results of this test may be used as elements of a fire assessment that takes into account all of the factors, which are pertinent to an assessment of the fire hazard of a particular end use.

SIGNIFICANCE AND USE
5.1 This test method determines the effectiveness of arc protective blankets in suprressing the combined effects of an arc flash and arc blast.  
5.2 The arc exposure energy is produced from controlled phase-to-ground arc fault. The resulting arc flash and blast energy are intentionally directed onto the test specimen to simulate worst case conditions.  
5.3 Test results will describe the maximum arc current and product of arc current and cycles at which test specimens block the energy without breakopen, ability to self-extinguish afterflaming, afterflame time and the detection of mechanical attachment failures during testing. Mechanical attachment failure and afterflame time are obtained from visual observations and video recording after each arc exposure.  
5.4 This test method maintains the arc protective blanket in a vertical position and does not involve movement except that resulting from the arc exposure.  
5.5 In this test method, test specimens are exposed at three arc current levels to determine the test specimen’s performance.
Note 2: In experimental testing, some blankets increase in protection (in value of kA*cycles to cause breakopen) as the arc current increases and some decrease as shown in Fig. 1. This test method is designed to recognize this behavior and to specify testing over the range of arc current levels including lower levels of 5 kA or 10 kA, or both.  
5.6 This test method specifies a standard set of exposure conditions. Different exposure conditions may produce different results.
Note 3: In addition to the standard set of exposure conditions, it is permitted to test using other conditions representative of the expected hazard, reported all non-standard test conditions that are used.
SCOPE
1.1 This test method is used to evaluate the ability of the arc protective blankets to withstand the effects of arc flash and arc blast in a configuration in which the blanket is hung or anchored near energized equipment. Specifically, this test method is used to determine the arc protective blanket’s (1) resistance to breakopen, (2) mechanical strength, and (3) ability to self-extinguish flames following a controlled arc exposure.  
1.2 This method is used to determine the performance of arc protective blankets in terms of: maximum arc current level expressed in kA and BTP (BTP) expressed as the product of arc current in kA and arc duration in number of cycles to cause breakopen (kA*cycles). Cycles are on the basis of 60 Hz.  
1.3 Blanket test specimens used in this test method are test size blankets of 152 ± 5 cm (60 ± 2 in.) by 122 ± 5 cm (48 ± 2 in.). The test specimen size is for testing purposes only. Commercially available arc protective blankets either larger or smaller than the test specimen size are covered by this standard.  
1.4 The arc protective blankets described in this test method are made of flame-resistant materials and are available in varying sizes and configurations based on the application.  
1.5 This test method shall be used to measure and describe the properties of materials, products, or assemblies in response to incident thermal (convective and radiant) and pressure energies generated by an electric arc under controlled laboratory conditions.  
1.6 The values stated in SI units shall be regarded as standard. The values given in parentheses are mathematical conversion to inch-pound or other units commonly used for arc testing.  
1.7 This standard shall not be used to describe or appraise the fire hazard or fire risk of materials, products, or assemblies under actual fire conditions. However, results of this test may be used as elements of a fire assessment, which takes into account all of the factors, which are pertinent to an assessment of the fire hazard of a particular end use.

SIGNIFICANCE AND USE
5.1 This test method is intended for the determination of the arc rating of a hand protective product material, or a combination of hand protective product materials.  
5.1.1 Because of the variability of the arc exposure, different heat transmission values are observed at individual sensors. Evaluate the results of each sensor in accordance with Section 12.  
5.2 This test method maintains the specimen in a static, vertical position and does not involve movement except that resulting from the exposure.  
5.3 This test method specifies a standard set of exposure conditions. Different exposure conditions have the potential to produce different results. In addition to the standard set of exposure conditions, other conditions are allowed and shall be documented in the reporting of the testing results.
SCOPE
1.1 This test method is used to determine the arc rating of hand protective products in the form of gloves, glove materials, glove material systems, or other protective products designed to fit on the hand and specifically intended for electric arc flash protection use as protective accessories for workers exposed to electric arc heat flux values from 84 to 25,120 kW/m2 [2 to 600 cal/cm2s].  
1.2 This test method will determine the arc rating of hand protective products made of materials which meet the following requirements for flame resistance: less than 150 mm [6 in.] char length, less than 2 s afterflame and no melt and drip when tested in accordance with Test Method D6413 or receive a reported 50 % probability of ignition of a material or flammable underlayer (see definition of ignition50) by this method.  
1.2.1 It is the intent of this test method to be used for hand protective products which are flame resistant or which have an adequate flame resistance for the required hazard (see 1.2). Non flame resistant hand protective products may be used as under layers in multiple-layer systems or tested for ignition probability.  
1.2.2 It is not the intent of this test method to be used for glove materials, which have been tested by Test Method F1959/F1959M as flat panels of material then sewn into hand protective products. Materials for hand protective products, which are not normally produced in flat panels or which display shrinkage making the material unacceptable to test on panels, shall be tested using this standard.  
1.2.3 Rubber insulating gloves meeting Specification D120 and leather protectors meeting Specification F696 are not covered by this test method and are specifically excluded from its Scope.  
1.2.4 Hand protective products tested by this method are new and ratings received by this method may be reduced or eliminated by hydrocarbon loading (gasoline, diesel fuel, transformer oil, etc.), sweat, dirt, grease, or other contaminants. The end user takes responsibility for use of hand protective products tested by this method when contaminated in such a manner which could reduce or eliminate the arc rating of the hand protective products.  
1.2.5 Gloves tested by this method provide no protection from electric shock. Insulated gloves for protection from electric shock are addressed under other standards including ASTM D120. This test method is designed to provide information for gloves used for electric arc protection only. This test method is not suitable for determining electrical protective properties of hand protective products.  
1.3 This test method is used to measure and describe the properties of hand protective products in response to convective and radiant energy generated by an electric arc under controlled laboratory conditions.  
1.4 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.

5.1.1 Because of the variability of the arc exposure, different heat transmission values may be observed at individual sensors. The results of each sensor are evaluated in accordance with Section 12.  
5.2 This test method maintains the specimen in a static, vertical position and does not involve movement except that resulting from the exposure.  
5.3 This test method specifies a standard set of exposure conditions. Different exposure conditions may produce different results.  
5.4 This specification covers the minimum performance criteria for arc resistance and other requirements for eye or face protective products used by workers who may be exposed to thermal hazards of momentary electric arcs or flame.  
5.5 The purchaser has the option to perform or have performed any of these tests in order to verify the performance of the eye or face protective product. Claims for failure to meet the specification are subject to verification by the manufacturer.Note 1—In addition to the standard set of exposure conditions, other conditions representative of the expected hazard may be used and shall be reported should this data be cited.
SCOPE
1.1 This test method and product specification is used to measure the arc rating and specify the requirements for products intended for use as eye or face protection for workers exposed to electric arcs that would generate heat flux values from 84 to 25 120 kW/m2 [2 to 600 cal/cm2s]. Products are tested as sold.  
1.2 This test method determines an arc rating for eye or face protective products. The faceshield, safety spectacle, goggle or or other applicable portions of the complete product must meet ANSI Z87.1. This excludes the textile or non ANSI Z87.1 testable parts of the hood assemblies or other tested products. This standard does not measure optical and impact properties (see ANSI Z87.1) but does specify requirements for optical and impact properties.  
1.3 The materials covered by this standard are in the form of faceshields attached to the head by protective helmets (hard hats), headgear, hood assemblies, safety spectacles or goggles. Faceshields, safety spectacles or goggles are tested with or without other face and head protective products, for example, sock hoods, balaclavas, sweat shirt hoods or jacket hoods.  
1.3.1 Fabric layers used in hood assemblies or other items tested under this standard shall meet the requirements of Specification F1506.  
1.4 This test method shall be used to measure and describe the properties of materials, products, or assemblies in response to convective and radiant energy generated by an electric arc under controlled laboratory conditions and does not purport to predict damage from light other than the thermal aspects measured.  
1.5 The values stated in SI units shall be regarded as standard except as noted. Within the text, alternate units are shown in brackets. The values stated in each system may no be exact equivalents; therefore, alternate systems must be used independently of the other. Combining values from the systems described in the text may result in nonconformance with the method.  
1.6 This standard does not purport to describe or appraise the effect of the electric arc fragmentation explosion and subsequent molten metal splatter, which involves the pressure wave containing molten metals and possible fragments of other materials except to the extent that heat energy transmission due to these arc explosion phenomena is reduced by test specimens.  
1.7 This standard shall not be used to describe or appraise the fire hazard or fire risk of materials, products, or assemblies under actual fire conditions. However, results of this test may be used as elements of a fire assessment which takes into account all of the factors whic...

SIGNIFICANCE AND USE
5.1 This practice can be used for a range of purposes including incident replication, development of improved arc rated protective products, and the determination of the response characteristics and design integrity of new or used arc rated finished products intended for use as protection for workers exposed to electric arcs.  
5.1.1 In-service garments can have very different wash and wear histories. Caution must be used when applying test results from a particular used garment to other used garments. Factors to consider include the garments’ wear histories, work environments, and tasks for which the garments were worn; the methods and facilities for garment maintenance; the number of launderings or processings the garments have been subjected to; and other factors that could impact the protective performance of different garments. Test results from specific used garments should be considered only an approximation of results that might be obtained from other used garments of the same type.  
5.1.2 Because of the variability of the arc exposure, different heat transmission values may result for individual sensors. The results of each sensor are evaluated in accordance with Section 12.  
5.2 This practice maintains the specimen in a static, vertical position and does not involve movement except that resulting from the exposure.

1.1 This practice provides procedural guidelines for conducting arc testing on finished products intended for use as thermal protection by workers who may be exposed to electric arcs.  
1.1.1 This practice is intended to provide procedural guidelines to improve consistency across testing groups. This practice is not intended to define the end points, parameters, or measures to be studied by the tester.  
1.1.2 This practice is supplemental to Test Methods F1959/F1959M and F2178. Protective materials used to manufacture arc rated finished products shall be tested according to Test Method F1959/F1959M prior to being tested according to this practice, and face protective products shall be tested according to Test Method F2178 prior to being tested according to this practice. Test Methods F1959/F1959M and F2178 provide definitive numeric arc ratings for materials intended for use in finished products worn by workers exposed to electric arcs.
1.1.2.1 Discussion—Face protective products such as face shields and hoods are tested as finished products using Test Method F2178. These items may be subsequently tested using this practice in order to determine the performance of the interface area between the face protective product and the arc flash PPE worn on the torso.

SIGNIFICANCE AND USE
This test method determines the effectiveness of arc protective blankets in suprressing the combined effects of an arc flash and arc blast.
The arc exposure energy is produced from controlled phase-to-ground arc fault. The resulting arc flash and blast energy are intentionally directed onto the test specimen to simulate worst case conditions.
Test results will describe the maximum arc current and product of arc current and cycles at which test specimens block the energy without breakopen, ability to self-extinguish afterflaming, afterflame time and the detection of mechanical attachment failures during testing. Mechanical attachment failure and afterflame time are obtained from visual observations and video recording after each arc exposure.
This test method maintains the arc protective blanket in a vertical position and does not involve movement except that resulting from the arc exposure.
In this test method, test specimens are exposed at three arc current levels to determine the test specimen’s performance.
Note 2—In experimental testing, some blankets increase in protection (in value of kA*cycles to cause breakopen) as the arc current increases and some decrease as shown in Fig. 1. This test method is designed to recognize this behavior and to specify testing over the range of arc current levels including lower levels of 5 kA or 10 kA, or both.  
This test method specifies a standard set of exposure conditions. Different exposure conditions may produce different results.
Note 3—In addition to the standard set of exposure conditions, it is permitted to test using other conditions representative of the expected hazard, reported all non-standard test conditions that are used.

SCOPE
1.1 This test method is used to evaluate the ability of the arc protective blankets to withstand the effects of arc flash and arc blast in a configuration in which the blanket is hung or anchored near energized equipment. Specifically, this test method is used to determine the arc protective blanket’s (1) resistance to breakopen, (2) mechanical strength, and (3) ability to self-extinguish flames following a controlled arc exposure.
1.2 This method is used to determine the performance of arc protective blankets in terms of: maximum arc current level expressed in kA and BTP (BTP) expressed as the product of arc current in kA and arc duration in number of cycles to cause breakopen (kA*cycles). Cycles are on the basis of 60 Hz.
1.3 Blanket test specimens used in this test method are test size blankets of 152 ± 5 cm (60 ± 2 in.) by 122 ± 5 cm (48 ± 2 in.). The test specimen size is for testing purposes only.
