Cellular plastics — Determination of tensile properties of rigid materials

Applies primarily to ceelular materials having a sufficient compression resistance to permit suitable gripping of the test pieces. The test piece of a given shape is subjected to a tensile stress, transmitted to the test piece by means of a suitable device. The corresponding stress-strain curve shall be recorded. In the case of low compression resistance the bonding of reinforcing metall plates to the gripping ends of test pieces is possible.
