1.1 These test methods cover procedures for braided and nonbraided fiber lacing and tying twines and tapes used to secure electrical harnesses, armatures, and similar apparatus. Both round twines and flat narrow tapes made from synthetic or natural fibers are included, and either may or may not be coated with waxes, resins, or elastomers.
1.2 The procedures appear as listed in the first column: ASTM Method Procedure Sections Reference Sampling 3 Conditioning 4 Weight (Yield) 5 to 13 D 123, D 1907 Breaking Strength and Knot Strength or Knot Slip 14 to 19 D 76 Resistance Volatile Content 20 to 27 Thickness and Width of Lacing Tapes and Diameter 28 to 35 D 374 of Twines Wax Content 36 to 42 Fiber Identification 43 to 45 D 276 Creep 46 to 53 Elastic Properties 54 to 61 Braid Pick of Lacing Tapes 62 to 68
1.3 The values stated in inch-pound units are to be regarded as the 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. Specific hazard statements are given in Section 37.
