SIGNIFICANCE AND USE
4.1 A clothing material’s ability to assist in the evaporation of liquid sweat by managing liquid moisture is of considerable importance when trying to maximize cooling and comfort benefits to the wearer while active. Understanding how much energy is released back to the skin is critical in determining their suitability for use in fabricating protective clothing systems or athletic wear.
4.1.1 The cooling energy released back to the wearer can be significantly affected by environmental conditions. Extreme care must be taken when using standard results measured under standard testing conditions to determine a material’s suitability for use in conditions outside the testing conditions.
4.2 This test method accounts for a clothing material’s ability to assist in evaporating liquid water during a sweating phase, as well as its ability to dry after the cessation of sweating.
4.2.1 A large amount of cooling energy released from clothing materials during active work (sweating) is often seen as a positive, as it would assist in keeping the body cooler.
4.2.2 A large amount of cooling energy released from clothing materials after active work (no sweating) is often seen as a negative, as it known to cause a chilling effect to the wearer.
4.2.3 The longer it takes for a clothing material to dry after becoming wet is perceived as a negative, as it increases the potential for chilling the wearer.
4.3 The thermal interchange between people and their environment is, however, an extremely complicated subject that involves many factors in addition to the steady-state resistance values of fabrics, films, coatings, foams, and leathers, including multi-layer assemblies. Therefore, the cooling provided from liquid evaporation may or may not indicate relative merit of a particular material or system for a given clothing application. While a possible indicator of clothing performance, measurements produced by the testing of fabrics have no proven correlation to the perfo...
SCOPE
1.1 This test method covers the measurement of the cooling energy released back to the wearer’s skin by a clothing material’s ability to move and evaporate controlled dosages of water under controlled ambient conditions using a sweating hot plate.
1.1.1 This test method establishes procedures for measuring the cooling energy during a simulated “sweating” phase and in a drying phase. Calculations are also provided to determine the drying time and how efficient the clothing material is at assisting in the evaporation of liquid water by comparing it to the maximum amount of energy that can be lost.
1.2 This test method does not address all properties that affect a clothing material’s ability to lose heat from the body. Consider measuring properties such as air permeability, insulation, and evaporative resistance.
1.3 The values in SI units shall be regarded as standard. No other units of measurement are included in the standard.
1.4 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.
1.5 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 test method is based on Test Method F903 for measuring resistance of chemical protective clothing materials to penetration by liquids. This test method is normally used to evaluate specimens from individual finished items of protective clothing and individual samples of materials that are candidates for items of protective clothing.
5.1.1 Finished items of protective clothing include gloves, arm shields, aprons, gowns, coveralls, hoods, and boots.
5.1.2 The phrase “specimens from finished items” encompasses seamed and other discontinuous regions as well as the usual continuous regions of protective clothing items.
5.2 Medical protective clothing materials are intended to be a barrier to blood, body fluids, and other potentially infectious materials. Many factors can affect the wetting and penetration characteristics of body fluids, such as surface tension, viscosity, and polarity of the fluid, as well as the structure and relative hydrophilicity or hydrophobicity of the materials. The surface tension range for blood and body fluids (excluding saliva) is approximately 42 to 60 dyn/cm (0.042 to 0.060 N/m) (1).7 To help simulate the wetting characteristics of blood and body fluids, the surface tension of the synthetic blood is adjusted to approximate the lower end of this surface tension range. The resulting surface tension of the synthetic blood is approximately 40 ± 5 dyn/cm (0.040 ± 0.005 N/m).
5.3 The synthetic blood mixture is prepared with a red dye to aid in visual detection and a thickening agent to simulate the flow characteristics of blood.
5.4 Part of the protocol in Procedures A and B in Table 1 for exposing the protective clothing material specimens with synthetic blood involves pressurizing the test cell to 13.8 kPa [2.0 psig]. This hydrostatic pressure has been documented to discriminate between protective clothing material performance and to correlate with visual penetration results that are obtained with a human factors validati...
SCOPE
1.1 This test method is used to evaluate the resistance of materials used in protective clothing to penetration by synthetic blood under conditions of continuous liquid contact. Protective clothing pass/fail determinations are based on visual detection of synthetic blood penetration.
1.1.1 This test method is not always effective in testing protective clothing materials having thick inner liners which readily absorb the synthetic blood.
1.2 This test method is a means for selecting protective clothing materials for subsequent testing with a more sophisticated barrier test as described in Test Method F1671/F1671M.
1.3 This test method does not apply to all forms or conditions of blood-borne pathogen exposure. Users of the test method must review modes for work/clothing exposure and assess the appropriateness of this test method for their specific application.
1.4 This test method addresses only the performance of materials or certain material constructions (for example, seams) used in protective clothing. This test method does not address the design, overall construction and components, or interfaces of garments, or other factors which may affect the overall protection offered by the protective clothing.
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 may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in nonconformance with the standard.
1.6 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.
1.7 This international standard was developed in accordance with internationally recognize...

SIGNIFICANCE AND USE
3.1 This practice contains the recommendations for minimal informational requirements for the identification of chemical protective clothing items. It is intended to provide the user with some of the basic information necessary for the proper selection and use of the chemical protective clothing.
3.2 For some items of chemical protective clothing, such as disposable chemical protective gloves, it is recognized that it is not practical that the labeling information be provided directly on the product. Therefore, it is permissible that this information be provided on the direct packaging that contains the product. As an example, it is possible to put the recommended product information on the dispenser box that contains multiple pairs of disposable chemical protective gloves.
3.3 Additional information beyond the content recommended by this practice is permitted to be applied to the label. This additional label content can include statements indicating compliance with specific standards, warnings, limitations associated with the product, and certain types of use, care, and maintenance information as addressed in Practice F2061.
3.4 Rules and regulations in Title 16 Code of Federal Regulations Part 303 cover the identification of fibers in textile products, specifically the disclosure of the fiber content and the manner of labeling products for purposes of applying tariffs on imported products and for informing the consumer. This practice is not intended to be a replacement for the requirements in 16 CFR 303, which may still apply to certain types of chemical protective clothing.
SCOPE
1.1 This practice covers the informational content of labels in or on chemical protective clothing. This practice also addresses putting label content on chemical protective clothing packaging when it is not practical to attach the label directly to the chemical protective clothing or print it on the chemical protective clothing item based on the size or type of the product.
1.2 This practice describes the recommended format and minimal content of the information to be included on the labels used for chemical protective clothing.
1.2.1 For the purposes of this practice, chemical protective clothing includes but is not limited to: suits, garments, and partial-body garments such as hoods, aprons, sleeve protectors, gloves, and footwear.
1.2.2 Protective clothing is defined as any single item or combination of items used for the purpose of isolating parts of the body from direct contact with a potential hazard. It does not include individual parts of a protective clothing item designed to be worn as part of another item (for example, a face shield or lens) unless it may be worn independently of the other items and still be used in a protective manner. For example, a glove or boot, unless permanently attached to a garment or suit, would be considered a protective clothing item requiring labeling, while a visor or vent valve would not. In summary, the intent of this practice is to only require labeling of parts of an ensemble that can be used independently for the protection of the user.
1.3 This practice does not cover user information provided by means other than item labeling such as instructions, informational packets, brochures, or other written means. User information is partly addressed in Practice F2061.
1.4 This practice excludes those items covered under 16 CFR 303 unless specifically designed for use as chemical protective clothing.
1.5 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.

SIGNIFICANCE AND USE
5.1 These practices establish standard procedures designed for qualitatively evaluating the performance characteristics of protective ensembles or ensemble elements in terms of comfort, fit, function, and durability. Limited quantitative measures are also provided.
5.2 These practices are suitable for both end users and manufacturers to evaluate performance characteristics of protective ensembles and ensemble elements.
5.2.1 End users may use these practices to qualitatively determine how well protective ensembles and ensemble elements (gloves, boots, and respirators) and ensemble components (communications systems, cooling devices, and undergarments) meet their particular application.
5.2.2 Manufacturers of protective ensembles and ensemble elements may use these practices to determine the qualitative performance characteristics in existing or proposed designs.
5.3 Option A permits a qualitative evaluation of protective ensemble or ensemble element mobility by subjecting the protective ensemble to a manned exercise routine. Option B permits a qualitative evaluation of protective ensemble or ensemble element function. Each procedure can be used to assess ensemble comfort and fit by relating test subject responses and by comparing the dimensions and weights of both the test subject and suit.
Note 1: The accumulation of suit and human subject dimension data may eventually be used by manufacturers or end users in standards to improve the sizing of chemical protective suits and the integration of ensemble components in protective ensembles.
5.4 The use of these practices is primarily for qualitative purposes only. In general, results from use of these practices on one type of ensemble may not be comparable to other test results on a different ensemble due to the subjective nature of test results.
5.5 Certain aspects of these practices are quantitative. The effect of wearing the ensemble or ensemble element can also be assessed by the measurement of t...
SCOPE
1.1 These practices are intended for evaluating protective ensembles and ensemble elements to determine the suitability of the ensemble or ensemble components in a work environment on the basis of its comfort, fit, function, and durability.
1.1.1 Option A is a manned exercise scenario intended to evaluate the impact of the ensembles and ensemble elements on wearer mobility when worn in a series of different physical exercises that are intended to evaluate the range of motion permitted by the ensemble or ensemble element.
1.1.2 Option B is a manned work task scenario intended to determine the impact of the ensemble or ensemble element on wearer function.
1.1.3 Recording the length of time used to complete these tasks provides a means for quantifying the impact of the ensemble or ensemble element on the wearer function.
1.1.4 Relating the ability of the subject to completely perform all tasks provides a qualitative assessment for the impact of the ensemble or ensemble element on wearer function.
1.1.5 The optional evaluation of ensembles or ensemble elements for liquid or vapor integrity following the exercise protocols provides a basis for evaluating the impact of wearing on ensemble or ensemble element integrity.
1.1.6 The optional evaluation of donning and doffing instructions provides a basis for evaluating the potential for errors which may impact the effectiveness of the ensemble.
1.2 These practices apply to protective ensembles and certain ensemble elements that are used for protection against different chemical, biological, physical, thermal, and other hazards, but are primarily useful for ensembles that include barrier layers such as liquid splash protective ensembles used for protection against hazardous chemicals or highly infectious diseases, or vapor protective ensembles used for chemical protection.
1.3 The values as stated in inch-pound units are to be regarded as the standard. The v...

SIGNIFICANCE AND USE
5.1 The purpose of this test method is to provide a measurable criterion of performance about the level of cut resistance provided by different types of protective garments and protected coverings worn by chainsaw operators.
5.2 This test method is intended to show to what level a protective garment can offer resistance to the cutting action of a chainsaw.
5.3 The protection which can be demonstrated by the garments and coverings tested in accordance with this test method is achieved by: (1) the cut resistance of the material to cutting when put in contact with saw chain; (2) pulling a part of the material or yarns in the material so that they are drawn into the chain and drive mechanism to block the chain movement; (3) the fibers of the materials used to demonstrate both high resistance to cutting and the capacity to absorb rotational energy, so that chain speed can be slowed down sufficiently to stop the movement of the saw chain; or (4) any combination of these.
5.4 This test method does not purport to evaluate comfort of lower body protective garments.
5.5 In case of a dispute arising from differences in reported test results when using this test method for acceptance testing of commercial shipments, the purchaser and the supplier should perform comparative tests to determine if there is a statistical bias between their laboratories. Competent statistical assistance is recommended for the investigation of bias. As a minimum, the two parties should take a group of test specimens from the same lot of components to be evaluated. The test specimens should then be randomly assigned in equal numbers to each laboratory for testing. If a bias is found, either its cause must be determined and corrected or the purchaser and the supplier must agree to interpret future test results in light of the known bias.
SCOPE
1.1 This test method measures cut resistance of garments and devices worn to protect the lower body (legs) when operating a chainsaw.
1.2 This test method may be used to test for compliance to minimum performance requirements in established safety standards.
1.2.1 By agreement between the purchaser and the supplier, or as required by established safety standards, it will be decided if this test method will be used to determine one or both of the following: (1) chain speed 50 (CS50), and (2) success/failure (jamming/chain stop or no cut in less than 1.5 s) at specified chain speed.
1.3 This test method may be used to determine levels of protection for areas of coverage as stipulated in established safety standards.
1.4 The values stated in SI units are to be regarded as standard.
Note 1: The values stated in each system may not be exact equivalents; therefore, each system must be used independently of the other, without combining values in any way.
1.5 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.
1.6 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 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
4.1 The thermal resistance, evaporative resistance, and total heat loss provided by fabrics, films, coatings, foams, and leathers, including multi-layer assemblies, is of considerable importance in determining their suitability for use in fabricating protective clothing systems.
4.1.1 The thermal resistance, evaporative resistance, and total heat loss can be significantly affected by environmental conditions. Extreme care must be taken when using results measured under standard testing conditions to determine a material’s suitability for use in conditions outside the testing conditions.
4.2 The thermal interchange between people and their environment is an extremely complicated subject that involves many factors in addition to the steady-state resistance values of fabrics, films, coatings, foams, and leathers, including multi-layer assemblies. Therefore, thermal resistance values, evaporative resistance values, and total heat loss measured on a hot plate may or may not indicate relative merit of a particular material or system for a given clothing application. While a possible indicator of clothing performance, measurements produced by the testing of fabrics have no proven correlation to the performance of clothing systems worn by people. Clothing weight, drape, tightness of fit, and so forth, can minimize or even neutralize the apparent differences between fabrics or fabric assemblies measured by this test method.
4.3 The thermal resistance and evaporative resistance of clothing systems and items can be measured with a heated sweating manikin in an environmental chamber in accordance with Test Methods F1291, F2370, and F3426.
SCOPE
1.1 This test method covers the measurement of the thermal resistance, evaporative resistance, and total heat loss under steady-state conditions of fabrics, films, coatings, foams, and leathers, including multi-layer assemblies, for use in clothing systems.
1.2 The range of this measurement technique for intrinsic thermal resistance is from 0.002 to 0.5 K·m2/W and for intrinsic evaporative resistance is from 0.0 to 1.0 kPa·m 2/W. The total heat loss range is from 0.0 to 1300 W/m2.
1.3 The values in SI units shall be regarded as standard. Other units of measurement are provided in this standard but are not regarded as standard.
1.4 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.

SIGNIFICANCE AND USE
5.1 Use this test method to measure the thermal protection provided by different materials, garments, clothing ensembles, and systems when exposed to a specified fire (see 3.2.2, 3.2.3, 4.1, and 10.4).
5.1.1 This test method does not simulate high radiant exposures, for example, those found in electric arc flash exposures, some types of fire exposures where liquid or solid fuels are involved, nor exposure to nuclear explosions.
5.2 This test method provides a measurement of garment and clothing ensemble performance on a stationary upright manikin of specified dimensions. This test method is used to provide predicted skin burn injury for a specific garment or protective clothing ensemble when exposed to a laboratory simulation of a fire. It does not establish a pass/fail for material performance.
5.2.1 This test method is not intended to be a quality assurance test. The results do not constitute a material’s performance specification.
5.2.2 The effects of body position and movement are not addressed in this test method.
5.3 The measurement of the thermal protection provided by clothing is complex and dependent on the apparatus and techniques used. It is not practical in a test method of this scope to establish details sufficient to cover all contingencies. Departures from the instructions in this test method have the potential to lead to significantly different test results. Technical knowledge concerning the theory of heat transfer and testing practices is needed to evaluate if, and which departures from the instructions given in this test method are significant. Standardization of the test method reduces, but does not eliminate, the need for such technical knowledge. Report any departures along with the results.
SCOPE
1.1 This test method is used to provide predicted human skin burn injury for single-layer garments or protective clothing ensembles mounted on a stationary upright instrumented manikin which are then exposed in a laboratory to a simulated fire environment having controlled heat flux, flame distribution, and duration. The average exposure heat flux is 84 kW/m2 (2 cal/s·cm2), with durations up to 20 s.
1.2 The visual and physical changes to the single-layer garment or protective clothing ensemble are recorded to aid in understanding the overall performance of the garment or protective clothing ensemble and how the predicted human skin burn injury results can be interpreted.
1.3 The skin burn injury prediction is based on a limited number of experiments where the forearms of human subjects were exposed to elevated thermal conditions. This forearm information for skin burn injury is applied uniformly to the entire body of the manikin, except the hands and feet. The hands and feet are not included in the skin burn injury prediction.
1.4 The measurements obtained and observations noted can only apply to the particular garment(s) or ensemble(s) tested using the specified heat flux, flame distribution, and duration.
1.5 This standard is used to measure and describe the response of materials, products, or assemblies to heat and flame under controlled conditions, but does not by itself incorporate all factors required for fire hazard or fire risk assessment of the materials, products, or assemblies under actual fire conditions.
1.6 This method is not a fire test response test method.
1.7 The values stated in SI units are to be regarded as standard. The values given in parentheses are mathematical conversions to inch-pound units or other units commonly used for thermal testing. If appropriate, round the non-SI units for convenience.
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.

1.2 This guide provides a short description of each referenced standard and then makes specific recommendations for the use of these standards. The referenced standards are organized under the following headings: Material Chemical Resistance, Material Physical Properties, Seam and Closure Performance, and Overall Clothing Performance.
1.3 No protocol can ensure the selection of protective clothing that guarantees worker protection. The purpose of testing is to generate data and information that will allow the selection of the most appropriate clothing. Ultimately, clothing selection is based on technical evaluation of available information and professional assessment of risk.
1.4 The values stated in SI units or in other units shall be regarded separately as standard. The values stated in each system must be used independently of the other, without combining values in any way.
1.5 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.
1.6 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.
