ASTM D2256-02<\/h3>\n

Historical Standard: Standard Test Method for Tensile Properties of Yarns by the Single-Strand Method<\/h4>\n
\n

ASTM D2256<\/h4>\n

Scope<\/strong><\/p>\n

1.1 This test method covers the determination of tensile properties of monofilament, multifilament, and spun yarns, either single, plied, or cabled with the exception of yarns that stretch more than 5.0 % when tension is increased from 0.05 to 1.0 cN\/tex (0.5 to 1.0 gf\/tex).<\/p>\n

1.2 This test method covers the measurement of breaking force and elongation of yarns and includes directions for the calculation of breaking tenacity, initial modulus, chord modulus, and breaking toughness.<\/p>\n

1.2.1 Options are included for the testing of specimens in: (A) straight, (B) knotted, and (C) looped form.<\/p>\n

1.2.2 Conditions of test are included for the testing of specimens that are: (1) conditioned air, (2) wet, not immersed, (3) wet, immersed, (4) oven-dried, (5) exposed to elevated temperature, or (6) exposed to low temperature.<\/p>\n

Note 1\u2014Special methods for testing yarns made from specific fibers; namely, glass, flax, hemp, ramie, and kraft paper and for specific products; namely, tire cords and rope, have been published: Test Method D 885, and Specification D 578.<\/p>\n

Note 2\u2014For directions covering the determination of breaking force of yarn by the skein method refer to Test Method D 1578.<\/p>\n

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 and health practices and determine the applicability of regulatory limitations prior to use.<\/i><\/p>\n
