Standard Test Method for Determining Impact Resistance of New Low Slope Roof Membranes Using Steel Balls (Z8295Z)

Importancia y uso:

6.1 This test method provides a means of evaluating new roof membranes for resistance to specific impact energies. The method evaluates new roof membranes when first applied and also after simulated deterioration caused by the ultraviolet radiation and moisture.

6.2 Use Class 2 for an impact resistance of 11.0 ± 0.3 J [8.1 ± 0.2 ft-lb] and Class 3 for an impact resistance of 19.4 ± 0.4 J [14.3 ± 0.3 ft-lb].
