1.1 This practice covers rules for designating one, two, or three-piece round wire leads used as conductors through glass seals in electron tubes. Stranded leads and leads for semiconductors are excluded.
1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this 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 and health practices and determine the applicability of regulatory limitations prior to use.

This practice covers the rules for naming one, two, or three-piece round wire leads used as conductors through glass seals in electron tubes, excluding stranded leads and leads for semiconductors. Each portion of designation should be separated by a dash (-). Materials for a component lead are generally designated using the chemical symbols. Claddings or platings are represented by numerical suffixes at the end of the material designation preceded by "C" (coating). For alloys that are unspecified, a numerical value between chemical symbols indicates the percent content of the material preceding the value. Descriptive suffixes are used to specify annealing conditions.View Less
