54,00 €

Détails

This test standard provides a procedure for determining the impact resistance performance of new prepared rigid roofing materials which are intended for use mainly on, but not restricted to, "Steep Slope" roof systems. The test uses the impact forces of freezer ice balls propelled to develop free-fall kinetic energies of the same size hail.
