11. Test report

Gives the conditions to determine the distribution of strength and rupture strain of ceramic filaments within a multifilament tow at room temperature by performing a single tensile test on a multifilament tow. Applicable to tows of continuous ceramic filaments which are assumed to act freely and independently when loading, and behave linearly elastic up to failure.
