    WK60330

    1. Scope

    1.1 This test method details the method for a laboratory based evaluation and rating of damage caused to a gypsum board outside 90 corner system when impacted by a hard body. The corner system is comprised of corner bead (as defined by Specification C1047), gypsum board (Specification C1396/C1396M), joint compound (Specification C475/C475M), and related fastening products (Specifications C754 and C1002 and AISI S220). 1.2 Units--The values stated in SI units are to be regarded as the standard. Inch/pound units are also shown. Within the text, the SI units are shown in brackets. The values stated in each system shall be used independent of the other. Values from the two systems shall not be combined. Combining values from the two systems may result in nonconformance with the standard. 1.3 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 determine the applicability of regulatory limitations prior to use. 1.4 There is no known ISO equivalent to this standard.

    Rationale

    Need to standardize the method used to determine the impact resistance of corner products. Currently, each manufacturer uses a different method. This will be used by contractors, homeowners, and so forth to determine which product is right for their specific application.

    The title and scope are in draft form and are under development within this ASTM Committee.
