This International Standard specifies methods for the determination of the breaking force and elongation at break of textile yarns taken from packages. Four methods are given: - A: manual; specimens are taken directly from conditioned packages; - B: automatic; specimens are taken directly from conditioned packages; - C: manual; relaxed test skeins are used after conditioning; - D: manual; specimens are used after wetting. Method C should be used in cases of dispute regarding elongation at break of the yarn. D is likely to give results differing, for both breaking force and elongation at break, from those obtained by method A, B or C. This International Standard specifies methods using constant rate of specimen extension (CRE) tensile testers. Testing on the now obsolete constant rate of travel (CRT) and constant rate of loading (CRL) instruments is covered, for information, in annex A, in recognition of the fact that these instruments are still in use and may be used by agreement. This International Standard applies to all types of yarn except glass yarns, elastomeric, aramid, ceramic, carbon, high molecular polyethylene (HMPE), ultra high molecular polyethylene (UHMPE), and polyolefin tape yarns. Textile glass - Yarns - Determination of breaking force and breaking elongation. This International Standard is applicable to yarns from packages but can be applied to yarns extracted from fabrics, subject to agreement between the interested parties. It is intended for the single-end (single-strand) testing of yarns.
