ASTM F289
1. Scope
1.1 This specification covers two grades of molybdenum wire less than 0.050 in. (1.27 mm) in diameter and one grade of molybdenum rod 1.00 in. (25.4 mm) or less in diameter as follows:
1.1.1 Grade 1 Commercially pure molybdenum wire suitable for leads, hooks, supports, heaters, and metal-to-glass seals.
1.1.2 Grade 2 Commercially pure molybdenum wire suitable for mandrel either black or cleaned.
1.1.3 Grade 3 Commercially pure molybdenum rod suitable for leads, hooks, supports, and metal-to-glass seals.
1.2 The term wire applies to all spooled or coiled material and 0.050 in. (1.3 mm) or less in diameter and to short cut lengths 0.020 in. (0.51 mm) or less in diameter.
1.3 The term rod applies to all material over 0.020 in. (0.51 mm) in diameter, supplied in straight lengths.
1.4 The values stated in inch-pound units are to be regarded as the standard. The metric equivalents of inch-pound units may be approximate, except for the size of the wire expressed in milligrams per 200 mm.
1.5 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.
