Standard Test Method for Impact Resistance of Class PB and PI Exterior Insulation and Finish Systems (EIFS)

SIGNIFICANCE AND USE
5.1 This specification determines levels of impact resistance under Classes PB and PI EIFS.  
5.2 This test method does not purport to simulate impact encountered in service.
SCOPE
1.1 This test method covers a procedure for rapidly deforming by impact an EIFS for evaluating the effect of such deformation.  
1.2 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance 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 to determine the applicability of regulatory limitations prior to use.
