Overview
SIST-TS CEN/TS 15658:2026 sets out procedures for determining the mechanical properties-specifically, the creep behaviour-of single filaments of ceramic fibres under high temperatures in a non-reactive environment. This technical specification addresses requirements for the hot grip method, ensuring that test conditions do not induce changes in the material properties due to chemical reactions with the environment. The standard is specifically applicable to continuous ceramic filaments (from tows, yarns, braids, and knitted structures) exhibiting a strain to failure of 5% or less.
Tests conducted according to SIST-TS CEN/TS 15658:2026 are crucial for industries relying on advanced technical ceramics where reliable performance under long-term high-temperature stress is essential.
Key Topics
Applications
The creep behaviour analysis of ceramic fibres at high temperatures is essential for:
- Aerospace: Ceramic fibres are used in composite materials for engines and thermal protection, where resistance to deformation under sustained load is critical.
- Energy and Power Generation: Insulating materials and reinforcement fibres in turbines and reactors must withstand harsh, hot environments.
- Automotive: Ceramics used in high-performance brake systems, exhausts, and sensor enclosures benefit from reliable high-temp creep resistance data.
- Industrial Furnaces and Kilns: Structural components and reinforcements in continuous high-temperature service.
- Research & Development: Material scientists depend on standardized mechanical property data to innovate and improve advanced ceramic applications.
Proper compliance with SIST-TS CEN/TS 15658:2026 ensures that manufacturers, testing laboratories, and end-users can reliably compare ceramic fibres' performance and suitability for critical applications.
