Historical Standard: ASTM F290-94(2005) Standard Specification for Round Wire for Winding Electron Tube Grid Laterals
SUPERSEDED (see Active link, below)
ASTM F290
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 and ).
1.3 The values stated in inch-pound units are to be regarded as the standard. The metric equivalents of inch-pound units may be approximate.
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.
2. Referenced Documents (purchase separately) The documents listed below are referenced within the subject standard but are not provided as part of the standard.
