ISO 17590:2025 pdf download,Fine ceramics (advanced ceramics, advanced technical ceramics) — Methods of tests for reinforcements — Determination of the tensile properties of ceramic filaments at elevated temperature in air using the hot grip technique.
ISO 17590:2025 presents a testing method for evaluating tensile properties, such as tensile strength, Young’s modulus, and fracture strain of ceramic filaments at elevated temperatures in air, employing the hot grip technique. It applies to continuous ceramic filaments sourced from either a multifilament bundle or a spool. However, it does not pertain to ceramic filaments that display creep behavior at the test temperature. Furthermore, the efficacy of the hot grip technique is limited by the temperature tolerance of the current ceramic adhesive.
