Поропласты жесткие. Испытания на изгиб. Часть 1. Определение прочности при изгибе
Название (англ.):
Cellular plastics, rigid; flexural tests; part 1: bending test
Описание (англ.):
Specifies a method of test for assessing the behaviour of a bar of rigid cellular plastic under the action of three-point bending. It may be used to determine either the load for a specified deformation or the load at break. The methodis not applicable to brittle cellular plastics and is limited to materials of 20 mm thickness or greater. A load is applied at a uniform rate by means of a loading edge to a test specimen supported at two positions. The load is applied perpendicularly in the middle between the two positions. The load at a specified deflection or at break is recorded. Cancels and replaces ISO 1209:1976.
