This document 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 give
identical results. To avoid such differences, this document is
restricted to the use of constant-rate-of-extension testing
machine.
It is applicable to all fibres, including crimped fibres,
provided that the length of fibre available enables the gauge
length specified in this document.
NOTE
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).
