Significance and Use

12.1 For the purpose of determining compliance with the specified limits for requirements of the properties listed in the following table, an observed value or calculated value shall be rounded as indicated in accordance with the rounding method of Practice E29.

Property	Rounded Unit for Observed or Calculated Value

Dimensions Chemical composition Hardness Electrical resistivity/conductivity	nearest unit in the last right-hand significant digit used in expressing the limiting value

Tensile strength Yield strength	nearest ksi [5 MPa]

Elongation
Below 5 %	nearest multiple of 0.5 %
5 % and over	nearest 1 %

Grain size
Under 0.060 mm	nearest multiple of 0.005 mm
0.060 mm and over	nearest 0.01 mm

1. Scope

1.1 This specification establishes requirements common to wrought copper and copper alloy wire and shall apply to Specifications B16/B16M, B99/B99M, B134/B134M, B159/B159M, B197/B197M, B206/B206M, B272, B301/B301M, B453/B453M, B967/B967M, and B974/B974M to the extent referenced therein.

1.2 The chemical composition, physical and mechanical properties, and all other requirements not included in this specification shall be prescribed in the product specification.

1.3 Units—Values stated in either SI units or inch-pound units are to be regarded separately as standard. Within the text, SI units are shown in brackets. 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.

1.4 The following safety hazard caveat pertains only to the test methods described in this specification. 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 and health practices and to determine the applicability of regulatory limitations prior to use.
