"Elastic" qualification of fibres . 14Bibliography . 15 SIST EN 15930:2010

1 Scope This test method covers the determination of the elasticity of fibres and may lead to classification of the fibre as elastic fibre (see Annex A).
It is applicable to single man-made crimped and uncrimped fibres. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.
