This document specifies the conditions for determination of the tensile properties of single filaments of ceramic fibre such as the tensile strength, Young modulus and fracture strain. This document applies to continuous ceramic filaments taken from tows, yarns, braids and knittings, which have strain to fracture less than or equal to 5 %. This document does not apply to carbon fibres that exhibit a nonlinear stress-strain curve. This document does not apply to checking the homogeneity of strength properties of fibres, or to assessing the effects of volume under stress. Methods of estimation of strength statistical parameters are indicated.
EN ISO 19630:2025 (CEN adoption of ISO 19630:2025) specifies a harmonized test method for determining the tensile properties of single ceramic filaments at ambient temperature. The standard covers measurement of tensile strength, Young’s modulus and fracture strain for continuous ceramic filaments taken from tows, yarns, braids and knittings, provided the filaments have a strain-to-fracture ≤ 5%. Tests are performed at a constant displacement rate and the document replaces the 2017 edition.
