中文名称:纺织纤维 单个纤维的断裂力和断裂伸长率的测定
英文名称:Textile fibres — Determination of breaking force and elongation at break of individual fibres

标准范围
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).
