scope:

Specifies the method and conditions of test for the determination of the breaking force and elongation at break of individual fibres in the conditioned or wet state. The determination of these fibre properties when carried out on different kinds of testing equipment, will not generally given identical results. To avoid such differences, this standard is restricted to the use of constant-rate-of-extension testing apparatus. The method is applicable to all fibres, including crimped fibres, provided that the length of fibre available enables the intial length specified in tis standard to be used.
