Four specimens are cut from a larger block sample with a hot wire saw. A bar of rectangular cross section is tested in flexure via one of the two methods: Test Method I—The bar rests on two supports and is loaded by means of a loading fitting or piece midway between the supports. Test Method II—The bar rests on two supports and is loaded at the two quarter points (by means of two loading fittings), each an equal distance from the adjacent support point. The distance between the loading fittings is one half of the support span.
