1. Scope

1.1 This specification covers round wire up to 0.006 in. (0.15 mm) in diameter for use as electron tube grid lateral winding wire.

1.2 Five classes of wire are covered based on their tensile properties (see 5.2 and 5.3).

1.3 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.

1.4 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.
