Standard Test Method for Thermal Endurance of Film-Insulated Round Magnet Wire

SIGNIFICANCE AND USE
5.1 This test method is useful in determining the thermal endurance characteristics and thermal indices of film-insulated round magnet wire in air (see 1.3). This test method is used as a screening test before making tests of more complex systems or functional evaluation. It is also used where complete functional systems testing is not feasible.  
5.2 Experience has shown that film-insulated wire and electrical insulating varnishes or resins can affect one another during the thermal exposure process. Test Method D3251 provides indications on the thermal endurance for a combination of insulating varnish or resin and film insulated wire. It is possible that interaction between varnish or resin and film insulation will increase or decrease the relative thermal life of the varnish and film insulated wire combination compared with the life of the film insulated wire tested without varnish.  
5.3 The conductor type or the surface condition of the conductor will affect the thermal endurance of film-insulated magnet wire. This test method is used to determine the thermal endurance characteristics of film insulation on various kinds of conductors. The use of sizes other than those specified in 7.1.1 is permissible but is not recommended for determining thermal endurance characteristics.  
5.4 The temperature index determined by this test method is a nominal or relative value expressed in degrees Celsius at 20 000 h. It is to be used for comparison purposes only and is not intended to represent the temperature at which the film insulated wire could be operated.  
5.5 There are many factors that influence the results obtained with this test method. Among the more obvious are the following:  
5.5.1 Wire size and film thickness.  
5.5.2 Moisture conditions during proof voltage tests.  
5.5.3 Oven construction:
5.5.3.1 Velocity of air.
5.5.3.2 Amount of replacement air.
5.5.3.3 Elimination of products of decomposition during thermal exposure.
5.5.3.4 Oven loading....
SCOPE
1.1 This test method covers determination of the thermal endurance of film-insulated round magnet wire in air at atmospheric pressure. It is not applicable to magnet wire with fibrous insulation, such as cotton or glass.  
1.2 This test method covers the evaluation of thermal endurance by observing changes in response to ac proof voltage tests. The evaluation of thermal endurance by observing changes in other properties of magnet wire insulation requires the use of different test methods.  
1.3 It is possible that exposure of some types of film insulated wire to heat in gaseous or liquid environments in the absence of air will give thermal endurance values different from those obtained in air. Consider this possibility when interpreting the results obtained by heating in air with respect to applications where the wire will not be exposed to air in service.  
1.4 It is possible that electric stress applied for extended periods at a level exceeding or even approaching the discharge inception voltage will change significantly the thermal endurance of film insulated wires. Under such electric stress conditions, it is possible that comparisons between materials will also differ from those developed using this method.  
1.5 This test method is similar to IEC 60172. Differences exist regarding specimen preparation.  
1.6 The values stated in inch-pound units are to be regarded as the standard. The SI units in parentheses are provided for information only and are not considered standard.  
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.

Standard Test Methods for Hookup Wire Insulation

ABSTRACT
These test methods detail the standard procedures for testing hookup wire insulations including all components of the insulation system used on single insulated conductors or an assembly of single insulated conductors such as a cable bundle and harness or flat ribbon cable. The insulating materials include not only the primary insulation over the conductor, but also insulating jackets over shielded constructions. The test procedures covered here shall be performed in the conditions or shall determine the properties, as follows: axial stability (longitudinal change) after thermal exposure; bondability to potting compounds; capacitance; cold bend test; concentricity; crush resistance; dielectric breakdown voltage; dimensions; dry-arc tracking; dynamic cut-through; fluid immersion; high temperature shock; insulation-continuity proof tests; insulation resistance; partial discharge (corona) inception and extinction voltage; relative thermal life and temperature index; strip force; surface resistance; tensile properties; vertical flame test; voltage rating of hook-up wire; voltage withstand test; and wet arc-tracking.
SCOPE
1.1 These test methods cover procedures for testing hookup wire.  
1.2 For the purposes of these test methods, hookup wire insulation includes all components of the insulation system used on single insulated conductors or an assembly of single insulated conductors such as a cable bundle and harness or flat ribbon cable.

Standard Test Method for Thermal Endurance of Coating Powders Used for Powder Coating Insulation Systems

SIGNIFICANCE AND USE
5.1 A major factor affecting the life of insulating materials is thermal degradation. It is possible that other factors, such as moisture and vibration, will cause failures after the material has been weakened by thermal degradation.  
5.2 Electrical insulation is effective in electrical equipment only as long as it retains its physical and electrical integrity. The following are potential indicators of thermal degradation: weight change, porosity, crazing, and generally a reduction in flexibility. Thermal degradation is usually accompanied by an ultimate reduction in dielectric breakdown.  
5.3 This test method is useful in determining the thermal endurance of coating powders applied over a steel substrate material.
SCOPE
1.1 This test method provides a procedure for evaluating thermal endurance of coating powders by determining the length of aging time at selected elevated temperatures required to achieve dielectric breakdown at room temperature at a pre-determined proof voltage. Thermal endurance is expressed in terms of a temperature index.  
1.2 This test method is applicable to insulating powders used over a substrate material of steel.  
1.3 Units—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, each system shall be used independently of the other. Combining values from the two systems is likely to result in non-conformance with 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. Specific precautionary statements are given in Section 7.  
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.

This specification covers round, aluminum-clad steel core wire used for mechanical reinforcement in the manufacture of aluminum conductors, aluminum-clad steel reinforced. The base metal shall be steel produced by the openhearth, electric-furnace, or basic-oxygen process and shall be of such composition that the finished clad wire shall have the properties and characteristics prescribed in this specification. The aluminum used for cladding shall have a purity and quantity sufficient to meet thickness and resistance requirements of this specification. The material shall conform to the required tensile properties such as stress, tensile strength, and elongation. The aluminum-clad steel core shall undergo elongation test, tension test, and torsion test. The elongation test shall be determined by an extensometer equipped with a vernier or other instrument reading. In the torsion test, a small tensile load shall be applied to the specimen during testing. The specimen shall be twisted by rotating one of the vises in the same direction until fracture occurs.
SCOPE
1.1 This specification covers round, aluminum-clad steel core wire with two designations of tensile strengths, AW2 (Normal Strength) and AW3 (High Strength).  
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 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.  
1.2.1 For conductor sizes designated by AWG, the requirements in SI units have been numerically converted from corresponding values stated or derived in inch-pound units. For conductor sizes designated by SI units only, the requirements are stated or derived in SI units.  
1.3 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 Specification for Copper-Clad Steel Electrical Conductor for CATV Drop Wire

ABSTRACT
This specification covers hard-drawn round copper-clad steel electrical conductor for CATV drop wire (coaxial cable center conductor). The wire shall be composed of a steel core with a substantially uniform and continuous copper cladding thoroughly bonded to it throughout. The size shall be expressed as the diameter of the wire. The steel wire shall conform to the prescribed tensile strength, elongation, and breaking strength. Requirements for (1) tension and torsion tests, (2) method of determining the electrical resistance, (3) cladding uniformity in terms of thickness, and (4) joint construction are detailed. The prescribed density of the wire to be taken for calculating mass/unit length, cross section, and so forth is given.
SCOPE
1.1 This specification covers 21 % conductivity hard-drawn round copper-clad steel wire for coaxial cable center conductors (Note 1).  
Note 1: Wire ordered to this specification is not intended for redrawing since it is furnished in the hard-drawn temper. If wire is desired for the purpose, the manufacturer should be consulted.  
1.2 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.  
1.3 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 Specification for High-Strength Zinc-Coated (Galvanized) Steel Core Wire for Use in Overhead Electrical Conductors

ABSTRACT
This specification covers the standard requirements for round, high-strength, zinc-coated (galvanized), steel core wire with Class A zinc coating used for mechanical reinforcement in the manufacture of special steel reinforced aluminum and aluminum-alloy conductors. The base metal shall be steel produced by the open-hearth, electric-furnace, or basic-oxygen process and the wire shall be cold drawn and coated with zinc. Joints may be made at any stage of processing prior to final cold drawing by the electric butt-weld or flash-welding process. Chemical analysis shall be conducted; wherein, the steel shall conform to the chemical composition requirements for carbon, manganese, phosphorus, sulfur, and silicon. The zinc-coated steel core wire shall conform to the tensile strength and elongation requirements which shall be obtained using a tensile test method. The material shall also undergo wrap and adherence tests; wherein, the wire shall be capable of being wrapped in a close helix without cracking or flaking.
SCOPE
1.1 This specification covers round, high-strength, zinc-coated (galvanized), steel core wire with Class A zinc coating (GA3) for use in overhead electrical conductors.  
1.2 This specification covers wire of diameter from 0.0500 in. to 0.1900 in. inclusive or 1.27 mm to 4.82 mm inclusive.  
1.3 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.  
1.4 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.
