Standard Specification for Wire for Use In Wire-Wound Resistors

ABSTRACT
This specification covers round wires and ribbons with controlled electrical properties made from magnetic and nonmagnetic class 1a-11 alloys. The wires and ribbons, which may have insulated coverings or enamel coatings, are recommended for use in wire-wound resistance units like precision resistors and other similar applications, but not for use as electrical heating elements. Each bare wire should conform to the requirements for nominal resistivity, elongation, thermal electromotive force with respect to copper, and the temperature coefficient of resistance contained in this specification. The nominal resistance per unit length for a round wire is calculated from the nominal resistivity and nominal cross-sectional area.
SCOPE
1.1 This specification covers round wire and ribbon with controlled electrical properties for use in wire-wound resistance units and similar applications, but not for use as electrical heating elements.  
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 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 become familiar with all hazards including those identified in the appropriate Safety Data Sheet (SDS) for this product/material as provided by the manufacturer, to establish appropriate safety, health, and environmental practices, and determine the applicability of regulatory limitations prior to use.

ASTM D4496-21e1(Test Method)
Standard Test Method for D-C Resistance or Conductance of Moderately Conductive Materials

SIGNIFICANCE AND USE
5.1 This test method is useful for the comparison of materials, as a quality control test, and for specification purposes.  
5.2 This test method is useful in the selection and use of materials in wires, cables, bushings, high-voltage rotating machinery, and other electrical apparatus in which shielding or the distribution of voltage stress is of value.  
5.3 Commercially available “moderately conductive” materials frequently are comprised of both conductive and resistive components (that is, cellulose fibers with colloidal carbon black particles attached to portions of the surfaces of those fibers, or discrete conductive particles adhered to the surfaces of electrical insulating polymers). Such commercially available materials are often manufactured in a manner that results in anisotropy of electrical conduction. Hence, the significance of tests using this test method depends upon the orientation of the specimen tested to the direction of the electric field and the relationship between this orientation and the orientation of the material in the electrical apparatus, which uses these materials.
SCOPE
1.1 This test method covers the determination of electrical resistance and electrical resistivity of materials that are generally categorized as moderately conductive and are neither good electrical insulators nor good conductors.  
1.2 This test method applies to the materials that exhibit volume resistivity in the range of 100 to 107 Ω-cm or surface resistivity in the range of 103 to 107 Ω (per square).  
1.3 This test method is designed for measurements at standard conditions of 23 °C and 50 % relative humidity, but its principles of operation can be applied to specimens measured at lower or higher temperatures and relative humidities.  
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 8.3.  
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 Method for Resistivity of Electrical Conductor Materials

ABSTRACT
This test method covers the determination of the electrical resistivity of metallic electrical conductor material. Weight resistivity accuracy may be adversely affected by possible inaccuracies in the assumed density of the conductor. The definition of resistivity and the equations for calculating volume resistivity and weight resistivity are given. Resistance shall be measured using an apparatus with a circuit configuration and instrumentation that has a resistance measurement capability of the prescribed accuracy. The test specimen requirements and the test procedure including: (1) determination of dimensions (such as length and cross-section), weight, and density, and (2) resistance measurement are detailed. The formula for calculating the corrected resistance, when the measurement is made at any temperature other than a reference temperature, is given. No statement of precision has been made and no work has been planned to develop such a statement. This test method has no bias because the value for resistivity is determined solely in terms of this test method.
SCOPE
1.1 This test method covers the determination of the electrical resistivity of metallic electrical conductor material. It provides for an accuracy of ±0.30 % on test specimens having a resistance of 0.00001 Ω (10 μΩ) or more. Weight resistivity accuracy may be adversely affected by possible inaccuracies in the assumed density of the conductor.  
1.2 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.  
1.3 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 Test Methods for Evaluating Connectability Characteristics of Electrical Conductor Materials

SIGNIFICANCE AND USE
5.1 These test methods develop comparative information useful for the design of stationary contacts for wire, cable, and other conductors.  
5.2 These test methods produce results, which are free of the influence of arbitrary connection systems.  
5.3 The influence of conductor surface pretreatments and platings can be evaluated by these test methods.  
5.4 The influence of environmental factors, such as high temperature and corrosive environment can be evaluated by these test methods.  
5.5 The results obtained by these test methods provide guidance on connection system design parameters, such as contact force and gas tightness requirements.
SCOPE
1.1 These test methods define procedures for the relative characterization of conductor material connectability on the basis of measurements of parameters important to the design and performance of electrical contacts and connections to and with such conductors for both power and signal applications.  
1.2 The parameters measured are contact resistance as a function of contact force, fretting sensitivity, and compressive relaxation.  
1.3 Provision is made for measurement of the connectability parameters at elevated temperature, or corrosive ambient, or both, as may be required for evaluation for particular applications.  
1.4 These test methods, using standardized specimen geometry and procedures, are applicable to conductor materials as employed in an electrical system and may be adapted for evaluation of connectability of materials in the form of actual connection system components.  
1.5 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this 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 become familiar with all hazards including those identified in the appropriate Safety Data Sheet (SDS) for this product/material as provided by the manufacturer, 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 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.
