This International Standard specifies the determination of in-plane tensile behaviour including stress-strain response under monotonic uniaxial testing of continuous fiber-reinforced ceramic matrix composites (CFRCMCs) at ambient temperature.

This International Standard addresses, but is not restricted to, various suggested test piece geometries, test piece fabrication methods, testing modes, testing rates, allowable bending, data collection and reporting procedures. This International Standard applies primarily to ceramic and/or glass matrix composites with continuous fiber reinforcement: uni-directional (1-D), bi-directional (2-D) and tri-directional (3-D) or other multi-directional reinforcements. Carbon fiber-reinforced carbon matrix (C/C) composites may also be tested using this International Standard, although caution is advised since this International Standard was developed primarily for CFRCMCs and any accommodations unique to C/C composites have not been included.

Values expressed in this International Standard are in accordance with the International System of Units (SI).
