ABSTRACT
These test methods cover procedures for measuring the diameter or thickness of round and flat wire (ribbon) used in electronic devices and lamps. Anvils shall be used in determining the thickness. The flatness and parallelism of the wire shall be checked using a monochromatic light source, a small optical parallel, and a cylindrical master standard wire gage.
SIGNIFICANCE AND USE
3.1 The methods contained in this standard are intended primarily for referee use, for laboratory measuring, and for certifying size of standard samples used for checking other measuring equipment that may be agreed upon between the supplier and the purchaser.
SCOPE
1.1 These test methods cover procedures for measuring the diameter or thickness of round and flat wire (ribbon) 0.060 in. (1.52 mm) maximum 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WITHDRAWN RATIONALE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 procedures for measuring the diameter or thickness of round and flat wire (ribbon) 0.060 in. (1.52 mm) maximum used in electronic devices and lamps.
Formerly under the jurisdiction of Committee F01 on Electronics, these test methods were withdrawn in November 2023. This standard is being withdrawn without replacement because Committee F01 was disbanded.
