適用范圍：This European standard specifies the conditions, apparatus and procedure for determining the distribution oftensile 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 andindependently 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 thetest temperature. Current experience with this technique is limited to 1 300 °C, because of the maximum applicationtemperature of ceramic glues.b) cold end method.NOTE 2 The cold-end method is limited to 1 700 °C in air and 2 000 °C in inert atmosphere because of the limits offurnaces.Both methods allow for a failure rate in the determination of distribution of tensile strain and tensile strength.
