Standard Test Methods of Testing Fine Round and Flat Wire for Electron Devices and Lamps
These test methods cover the testing of fine wire, flat or round, approximately 0.010 in. (0.25 mm) and smaller in diameter or thickness, used in electronic devices and lamps. Chemical analysis of the material shall be made in accordance with the requirements prescribed. The procedures in determining the out-of-roundness, edgewise curvature of ribbon, and straightness of straightened round wire are presented in details. Tension test and electrical resistivity test shall be performed to meet the requirements prescribed.
1.1 These test methods cover the testing of fine wire, flat or round, approximately 0.010 in. (0.25 mm) and smaller in diameter or thickness, used in electronic devices and lamps.
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 establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
