This test method covers the preparation, mounting, and testing of high-modulus single-filament materials [over > 21 10⁹ Pa (> 3 10⁶ psi)] for the determination of tensile strength and Young's modulus, at room temperature.

Formerly under the jurisdiction of Committee C28 on Advanced Ceramics, this test method was withdrawn in July 1998 in accordance with section 10.5.3.1 of the Regulations Governing ASTM Technical Committees, which requires that standards shall be updated by the end of the eighth year since the last approval date.

1.1 This test method covers the preparation, mounting, and testing of high-modulus single-filament materials [over > 21 10 ⁹ Pa (> 3 10⁶ psi)] for the determination of tensile strength and Young's modulus, at room temperature.

1.2 This test method is limited to single filaments utilizing a fixed gage length at least 2000 times longer than the nominal filament diameter.

1.3 This standard may involve hazardous materials, operations, and equipment. This standard does not purport to address all of the safety concerns 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.
