scope:

This International Standard specifies the method and conditions of test for the determination of the breaking strength and elongation of individual fibres. The method is applicable to man-made fibres, including crimped fibres, provided that the available length of fibre enables a gauge length (effective distance between the fibre nountings) of 10 mm or 20 mm to be used. The accuracy in the measurement of the elongation which arises from increased test length indicates that, wherever possible, the longer gauge length should be used.
