1.1 This International Standard specifies methods for the determination of the breaking force andelongation 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.1.2 Method C is used in cases of dispute regarding elongation at break of the yarn.NOTE Methods A, B and C are expected to give the same results for yarn strength, but Method C might give somewhat truer (and higher) values of elongation than
