Standard Method for Measuring Relative Resistance of Wall, Floor, and Roof Construction to Impact Loading

SCOPE
1.1 This method covers the measurement of the relative resistance of wall, floor, and roof construction to impact loading. The test is not applicable to doors.  
1.2 The values stated in SI units are to be regarded as 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.
