(Test Method)Standard Test Methods of Testing Fine Round and Flat Wire for Electron Devices and Lamps (Withdrawn 2023)
Standard Test Methods of Testing Fine Round and Flat Wire for Electron Devices and Lamps (Withdrawn 2023)
ABSTRACT
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.
SCOPE
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.
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.
WITHDRAWN RATIONALE
These test methods covered 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.
Formerly under the jurisdiction of Committee F01on Electronics, these test methods were withdrawn in November 2023. This standard is being withdrawn without replacement because Committee F01 was disbanded.
