1.Scope 1.1 This test standard provides a procedure for determining the impact resistance performance of new roof coverings from falling hail assessing the resistance of new roofing systems from the impact energy associated with various size hail. Propelled ice balls are used to simulate falling hailstones. 1.2 This test method defines test specimens and test panels, defines a procedure for determining impact locations on test specimens, provides impact (kinetic) energies of propelled ice balls, provides a method for impacting test specimens with ice balls, and specifies parameters that must be recorded and reported. 1.3 This standard is intended to verify that products as described will meet minimum specific stated conditions of impact resistance performance. This performance criterion is useful in determining the potential suitability of these products under hailstorm conditions. 1.4 It is not the intend intent of this standard to impact roof coverings roofing systems that have been placed in service. This standard is intended for the testing of new roof coverings roofing systems. 1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and to determine the applicability of regulatory limitations prior to use.
The title and scope are in draft form and are under development within this ASTM Committee.
