5.1 Rigid foam such as RCPS is used in the building construction industry. Because it is sensitive to certain components contained in adhesives which cause it to dissolve, it is important to have a test method to determine whether an adhesive is compatible with RCPS foam. This test method would help the end user decide which adhesive to use with RCPS foam by quantitatively measuring the amount of cavitation formed by the components contained in the adhesive.

1.1 This test method covers a practical means of measuring the degree of rigid cellular polystyrene (RCPS) foam cavitation damage when an adhesive is used to bond this substrate.

1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.

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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
