Standard Specification for Round Wire for Winding Electron Tube Grid Laterals

ABSTRACT
This specification covers round wires made from UNS N02211, UNS N10001, or N03300 nickel alloy or molybdenum, with diameters within a specified range, for winding electron tube grid laterals. The wires are classified into five classes based on tensile properties. All wires should conform to the required values of tensile strength, yield strength, working range, and elongation properties. The surface of each bare wire should be bright and free from cracks, slivers, fissures, lubricants, or other detrimental defects, while all platings should be free from bubbles, flakes, blisters, porosity, and plating salts. Wires should be spooled in one continuous length and in such a manner that it can be unwound under reasonable tension without binding or becoming distorted.
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.
