Scope: This European standard specifies the conditions, apparatus and procedure for determining the distribution of tensile strength and tensile strain to failure of ceramic filaments in multifilament tows at high temperature in air, vacuum or a controlled inert atmosphere.This part of EN 1007 applies to tows of continuous ceramic filaments, which are assumed to act freely and independently under loading and behave linearly elastic up to failure. Two methods are proposed depending on the temperature of the ends of the tow: a) hot end method; NOTE 1 The application of the hot end method is restricted by ceramic glues with sufficient shear strengths at the test temperature. Current experience withThis technique is limited to 1300 ℃, because of the maximum application temperature of ceramic glues. b) cold end method. NOTE 2 The cold-end method is limited to 1700 ℃ in air and 2000 ℃ in inert atmosphere because of the limits of furnaces. Both methods allow for a failure rate in the determination of distribution of tensile strain and tensile strength.
