Standard Test Method for Sag of Tungsten Wire
ASTM F269-60
Organization:
ASTM - ASTM International
Year: 2025
Abstract: This test method covers a determination of the sag properties of tungsten wire. The specimen of tungsten wire to be tested for sag shall have a clean, bright surface and should have the required length. With the aid of external heat, the test specimen shall be bent into a hairpin-shape until it reached the required distance between the ends. The formed test specimen shall be of sufficient length so that when clamped in the fixture, the exposed lengths measured from the top of the apex will be of required distance.

| scope | 1.1 This test method covers a determination of the sag properties of tungsten wire 0.030 in. (0.76 mm) and over in diameter. 1.2 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. 1.3 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee. | |
