1.1This practice describes standardized procedures for the preparation, spraying, packaging, and shipping of fresh spray polyurethane foam (SPF) insulation product samples to be tested for their emissions of volatile organic compounds (VOCs) and semi-volatile organic compounds (SVOCs). These procedures are applicable to both closed-cell and open-cell SPF insulation products. Potential chemical emissions of interest include blowing agents, solvents, aldehydes, amine catalysts, diisocyanates, and flame retardants.

1.2Typically, SPF insulation samples are prepared at one location, such as a chemical manufacturing facility or a field product installation site. The newly prepared samples are preserved in a sealed bag, placed in a secondary container, and then shipped to a laboratory for testing.

1.3The spraying of SPF insulation products is only to be performed by trained individuals using professional spraying equipment under controlled conditions. The details of the spraying equipment and spraying procedures are based on industry practice and are outside of the scope of this practice.

1.4This practice also describes procedures for the laboratory preparation of test specimens from open-cell and closed-cell SPF insulation product samples. These specimens are prepared for testing in small-scale chambers following Guide D5116 and in micro-scale chambers that are described in Test Method D8142.

1.5Procedures for VOC and SVOC emission testing, gas sample collection and chemical analysis are outside of the scope of this practice. Such procedures will need to address the potential for emissions of some SVOCs, for example, amine catalysts, flame retardant and isocyanates, to adhere to the chamber walls.

1.6The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

1.7This 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.

1.8This 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.
