This International Standard specifies the method and conditions of test for the determination of the break-ing 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 give identical results. To avoid such differences, this International Standard is restricted to the use of constant-rate-of-extension testing appar-atus.
The method is applicable to all fibres, including crimped fibres, provided that the length of fibre avail-able enables the initial length specified in this Inter-national Standard to be used.
NOTE 1 For natural fibres (especially wool and cotton) the breaking test most commonly performed is that of bundles of fibres (see ISO 3060 and IWTO 32-82).
