Standard Test Method for Concentration of Pinhole Detections in Moisture Barriers on Metal Jacketing

SIGNIFICANCE AND USE
5.1 Corrosion on the interior surface of metal jacketing can be caused by the formation of a galvanic cell between the dissimilar metals of the pipe and jacket or by crevice or pitting corrosion.  
5.2 The application of a moisture barrier to the interior surface of the metal jacketing inhibits this corrosion by interfering with the galvanic cell formation or by preventing water from contacting the interior metal surface.  
5.3 Holes in the moisture barrier decrease its effectiveness in preventing corrosion. Large holes, scratches, or tears in the moisture barrier visible to the naked eye are easily discerned and are cause for rejection of the metal jacketing.  
5.4 Small holes called pinholes or holidays that are not visible to the naked eye but are large enough to allow corrosion are a significant concern and should be avoided to the extent possible.  
5.5 This test method is used to quantify the concentration of pinhole detections present in a moisture barrier for the purpose of quality control on metal jacketing with an applied moisture barrier.  
5.6 Examples of standards which have specific requirements for the maximum allowable concentration of pinhole detections in the moisture barrier are Specifications C1729 and C1767.
SCOPE
1.1 This test method covers the determination of the concentration of pinhole detections in a moisture barrier film or coating that is applied to the interior surface of metal jacketing.  
1.2 Since this method relies on the completion through the metal jacketing of an electrical circuit, this method is only applicable to jacketing that is electrically conductive and has a moisture barrier applied which is not electrically conductive.  
1.3 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered 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.

Standard Test Methods for Thickness of Solid Electrical Insulation

SIGNIFICANCE AND USE
5.1 Some electrical properties, such as dielectric strength, vary with the thickness of the material. Determination of certain properties, such as relative permittivity (dielectric constant) and volume resistivity, usually require a knowledge of the thickness. Design and construction of electrical machinery require that the thickness of insulation be known.
SCOPE
1.1 These test methods cover the determination of the thickness of several types of solid electrical insulating materials employing recommended techniques. Use these test methods except as otherwise required by a material specification.  
1.2 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.  
1.3 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.

Standard Test Method for Dust-and-Fog Tracking and Erosion Resistance of Electrical Insulating Materials

SIGNIFICANCE AND USE
6.1 Method—It is possible that electrical insulation in service will fail as a result of tracking, erosion, or a combination of both, if exposed to high relative humidity and contamination environments. This is particularly true of organic insulations in outdoor applications where the surface of the insulation becomes contaminated by deposits of moisture and dirt, for example, coal dust or salt spray. This test method is an accelerated test that simulates extremely severe outdoor contamination. It is believed that the most severe conditions likely to be encountered in outdoor service in the United States will be relatively mild compared to the conditions specified in this test method.  
6.2 Test Results—Materials can be classified by this test method as tracking-resistant, tracking-affected, or tracking-susceptible. The exact test values for these categories as they apply to specific uses will be specified in the appropriate material specifications, but guideline figures are suggested in Note 4. Tracking-resistant materials, unless erosion failure occurs first, have the potential to last many hundreds of hours (Note 5). Erosion, though it is possible that it will progress laterally, generally results in a failure perpendicular to the specimen surface. Therefore, compare only specimens of the same nominal thickness for resistance to tracking-induced erosion. Estimate the extent of erosion from measurements of the depth of penetration of the erosion. Place materials that are not tracking-susceptible in three broad categories—erosion-resistant, erosion-affected, and erosion-susceptible. When the standard thickness specimen is tested, the following times to failure typify the categories (Note 6):    
Erosion-susceptible  
5 h to 50 h  
Erosion-affected  
50 h to 200 h  
Erosion-resistant  
over 200 h
Note 4: Tracking-susceptible materials usually fail within 5 h. Tracking-affected materials usually fail before about 100 h.
Note 5: This information is derive...
SCOPE
1.1 This test method is intended to differentiate solid electrical insulating materials with respect to their resistance to the action of electric arcs produced by conduction through surface films of a specified contaminant containing moisture. Test Methods D2302, D2303, D3638, and D5288 are also useful to evaluate materials.  
1.2 Units—The values stated in SI units are the standard. The inch-pound units in parentheses are for information only. 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.  
1.3 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.
Note 1: There is no equivalent ISO standard.  
1.4 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.

Standard Test Method for Thermal Endurance of Rigid Electrical Insulating Materials

SIGNIFICANCE AND USE
6.1 Thermal degradation is often a major factor affecting the life of insulating materials and the equipment in which they are used. The temperature index provides a means for comparing the thermal capability of different materials in respect to the degradation of a selected property (the aging criterion). This property needs to directly or indirectly represent functional needs in application. For example, it is possible that a change in dielectric strength will be of direct, functional importance. However, more often it is possible that a decrease in dielectric strength will indirectly indicate the development of undesirable cracking (embrittlement). A decrease in flexural strength has the potential to be of direct importance in some applications, but also has the potential to indirectly indicate a susceptibility to failure in vibration. Often, it is necessary that two or more criteria of failure be used; for example, dielectric strength and flexural strength.  
6.2 Other factors, such as vibration, moisture and contaminants, have the potential to cause failure after thermal degradation takes place. In this test method, water absorption provides one means to evaluate such considerations.  
6.3 For some applications, the aging criteria in this test method will not be the most suitable. Other criteria, such as elongation at tensile or flexural failure, or resistivity after exposure to high humidity or weight loss, have the potential to serve better. The procedures in this test method have the potential to be used with such aging criteria. It is important to consider both the nature of the material and its application. For example, it is possible that tensile strength will be a poor choice for glass-fiber reinforced laminates, because it is possible that the glass fiber will maintain the tensile strength even when the associated resin is badly deteriorated. In this case, flexural strength is a better criterion of thermal aging.  
6.4 When dictated by the needs of t...
SCOPE
1.1 This test method2 provides procedures for evaluating the thermal endurance of rigid electrical insulating materials. Dielectric strength, flexural strength, or water absorption are determined at room temperature after aging for increasing periods of time in air at selected-elevated temperatures. A thermal-endurance graph is plotted using a selected end point at each aging temperature. A means is described for determining a temperature index by extrapolation of the thermal endurance graph to a selected time.  
1.2 This test method is most applicable to rigid electrical insulation such as supports, spacers, voltage barriers, coil forms, terminal boards, circuit boards and enclosures for many types of application where retention of the selected property after heat aging is important.  
1.3 When dielectric strength is used as the aging criterion, it is also acceptable to use this test method for some thin sheet (flexible) materials, which become rigid with thermal aging, but is not intended to replace Test Method D1830 for those materials which must retain a degree of flexibility in use.  
1.4 This test method is not applicable to ceramics, glass, or similar inorganic materials.  
1.5 The values stated in metric units are to be regarded as standard. Other units (in parentheses) are provided for information.  
1.6 When determining the thermal endurance of rigid EIM, the basic concepts in this standard follow IEEE 1, IEEE 98, and IEEE 101.  
1.7 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. A specific warning statement is given in 11.3.4.

Standard Test Method for Smoke Obscuration of Insulating Materials Contained in Electrical or Optical Fiber Cables When Burning in a Vertical Cable Tray Configuration

SIGNIFICANCE AND USE
5.1 This test method provides a means to measure a variety of fire-test-response characteristics associated with smoke obscuration and resulting from burning the electrical insulating materials contained in electrical or optical fiber cables. The specimens are allowed to burn freely under well ventilated conditions after ignition by means of a propane gas burner.  
5.2 Smoke obscuration quantifies the visibility in fires.  
5.3 This test method is also suitable for measuring the rate of heat release as an optional measurement. The rate of heat release often serves as an indication of the intensity of the fire generated. Test Method D5537 provides means for measuring heat release with the equipment used in this test method.  
5.4 Other optional fire-test-response characteristics that are measurable by this test method are useful to make decisions on fire safety. The most important gaseous components of smoke are the carbon oxides, present in all fires. They are major indicators of the toxicity of the atmosphere and of the completeness of combustion, and are often used as part of fire hazard assessment calculations and to improve the accuracy of heat release measurements. Other toxic gases, which are specific to certain materials, are less crucial for determining combustion completeness.  
5.5 Test Limitations:  
5.5.1 The fire-test-response characteristics measured in this test method are a representation of the manner in which the specimens tested behave under certain specific conditions. Do not assume they are representative of a generic fire performance of the materials tested when made into cables of the construction under consideration.  
5.5.2 In particular, it is unlikely that this test method is an adequate representation of the fire behavior of cables in confined spaces, without abundant circulation of air.  
5.5.3 This is an intermediate-scale test, and the predictability of its results to large scale fires has not been determined. Some information ...
SCOPE
1.1 This is a fire-test-response standard.  
1.2 This test method provides a means to measure the smoke obscuration resulting from burning electrical insulating materials contained in electrical or optical fiber cables when the cable specimens, excluding accessories, are subjected to a specified flaming ignition source and burn freely under well ventilated conditions.  
1.3 This test method provides two different protocols for exposing the materials, when made into cable specimens, to an ignition source (approximately 20 kW), for a 20 min test duration. Use it to determine the flame propagation and smoke release characteristics of the materials contained in single and multiconductor electrical or optical fiber cables designed for use in cable trays.  
1.4 This test method does not provide information on the fire performance of electrical or optical fiber cables in fire conditions other than the ones specifically used in this test method, nor does it measure the contribution of the cables to a developing fire condition.  
1.5 Data describing the burning behavior from ignition to the end of the test are obtained.  
1.6 The production of light obscuring smoke is measured.  
1.7 The burning behavior is documented visually, by photographic or video recordings, or both.  
1.8 The test equipment is suitable for making other, optional, measurements, including the rate of heat release of the burning specimen, by an oxygen consumption technique and weight loss.  
1.9 Another set of optional measurements are the concentrations of certain toxic gas species in the combustion gases.  
1.10 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. (See IEEE/ASTM SI 10.)

Standard Test Method for Heat Release, Flame Spread, Smoke Obscuration, and Mass Loss Testing of Insulating Materials Contained in Electrical or Optical Fiber Cables When Burning in a Vertical Cable Tray Configuration

SIGNIFICANCE AND USE
5.1 This test method provides a means to measure a variety of fire-test-response characteristics associated with heat and smoke release and resulting from burning the materials insulating electrical or optical fiber cables, when made into cables and installed on a vertical cable tray. The specimens are allowed to burn freely under well ventilated conditions after ignition by means of a propane gas burner. The ignition source used in this test method is also described as a premixed flame flaming ignition source in Practice E3020, which contains an exhaustive compilation of ignition sources.  
5.2 The rate of heat release often serves as an indication of the intensity of the fire generated. General considerations of the importance of heat release rate are discussed in Appendix X1 and considerations for heat release calculations are in Appendix X2.  
5.3 Other fire-test-response characteristics that are measurable by this test method are useful to make decisions on fire safety. The test method is also used for measuring smoke obscuration. The apparatus described here is also useful to measure gaseous components of smoke; the most important gaseous components of smoke are the carbon oxides, present in all fires. The carbon oxides are major indicators of the completeness of combustion and are often used as part of fire hazard assessment calculations and to improve the accuracy of heat release measurements.

SCOPE
1.1 This is a fire-test-response standard.  
1.2 This test method provides a means to measure the heat released and smoke obscuration by burning the electrical insulating materials contained in electrical or optical fiber cables when the cable specimens, excluding accessories, are subjected to a specified flaming ignition source and burn freely under well ventilated conditions. Flame propagation cable damage, by char length, and mass loss are also measured.  
1.3 This test method provides two different protocols for exposing the materials, when made into cable specimens, to an ignition source (approximately 20 kW), for a 20 min test duration. Use it to determine the heat release, smoke release, flame propagation and mass loss characteristics of the materials contained in single and multiconductor electrical or optical fiber cables.  
1.4 This test method does not provide information on the fire performance of materials insulating electrical or optical fiber cables in fire conditions other than the ones specifically used in this test method nor does it measure the contribution of the materials in those cables to a developing fire condition.  
1.5 Data describing the burning behavior from ignition to the end of the test are obtained.  
1.6 This test equipment is suitable for measuring the concentrations of certain toxic gas species in the combustion gases (see Appendix X4).  
1.7 The values stated in SI units are to be regarded as standard (see IEEE/ASTM SI-10). The values given in parentheses are mathematical conversions to inch-pound units that are provided for information only and are not considered standard.

Standard Test Method for Glow-Wire Ignition of Materials

SIGNIFICANCE AND USE
5.1 During operation of electrical equipment, including wires, resistors, and other conductors, it is possible for overheating to occur under certain conditions of operation, or when malfunctions occur. When this happens, a possible result is ignition of the adjacent insulation material.  
5.2 This test method assesses the susceptibility of electrical insulating materials to ignition as a result of exposure to a glowing wire.  
5.3 This test method determines the minimum temperature required to ignite a material by the effect of a glowing heat source, under the specified conditions of test.  
5.4 This method is suitable, subject to the appropriate limitations of an expected precision of ±15 %, to categorize materials.  
5.5 In this procedure, the specimens are subjected to one or more specific sets of laboratory conditions. If different test conditions are substituted or the end-use conditions are changed, it is not always possible by or from this test to predict changes in the fire-test-response characteristics measured. Therefore, the results are valid only for the fire test exposure conditions described in this procedure.
SCOPE
1.1 This test method covers the minimum temperature required to ignite insulating materials using a glowing heat source. In a preliminary fashion, this test method differentiates between the susceptibilities of different materials with respect to their resistance to ignition due to an electrically-heated source.  
1.2 This test method applies to molded or sheet materials available in thicknesses ranging from 0.25 mm to 6.4 mm.  
1.3 This test method is not valid for determining the ignition behavior of complete electrotechnical equipment, since the design of the electrotechnical product influences the heat transfer between adjacent parts.  
1.4 This test method measures and describes the response or 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.  
1.5 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. (See IEEE/ASTM SI-10 for further details.)For specific precautionary statements, see Section 9.  
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. For specific precautionary statements, see Section 9.  
1.7 Fire testing is inherently hazardous. Adequate safeguards for personnel and property shall be employed in conducting these tests.
Note 1: Although this test method and IEC 60695-2-12 differ in approach and in detail, data obtained to determine the glow-wire flammability index (GWFI) using either test method are technically similar. Although this test method and IEC 60695-2-13 differ in approach and in detail, data obtained to determine the glow-wire ignition temperature (GWIT) using either test method are technically similar.  
1.8 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.

1.3 It is intended that all definitions in this terminology standard originating in a specific standard under the jurisdiction of Committee D09 be identical to definitions of the same terms as printed in standards of originating technical subcommittees, with the exceptions of: (1) deletion of any part of the Discussion included in another standard that refers specifically to the use of a term in that standard; (2) figure numbers and corresponding references; and (3) in this terminology standard, a parenthetical addition of a reference to one or more technical standards in which the term is used and the year in which the term was added to this compilation.  
1.3.1 Definitions contained in this terminology standard which did not originate in a specific standard under the jurisdiction of Committee D09, or which originated in a standard that has since been revised or withdrawn, and that have been appropriately balloted, shall also be included in this terminology standard.  
1.4 It is permissible to include symbols as part of the representation of terms, where appropriate.  
1.5 It is not intended that this terminology standard include symbols (except as noted in 1.4). It is also permissible to include acronyms and abbreviations referring directly to defined terms.  
1.6 Revisions and additions to those definitions in this terminology standard which originate in a specific standard under the jurisdiction of Committee D09 are to be made as a product of a collaborative effort between Subcommittee D09.94 and the corresponding technical subcommittee of Committee D09, with Subcommittee D09.94 providing editorial advice to the technical subcommittees.  
1.7 Each definition in this terminology standard shall be accompanied by the year in which it was first incorporated into the standard, placed at the end in parentheses. All discussions shall also carry a date; it is possible that the discussion date is different from the definition date.  
1.8 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.
