1.1''This guide describes the steps for developing improved laboratory accelerated weathering tests for predicting the natural weathering effects on building sealant systems and for using those tests in development of methods for design life prediction of the systems.

1.2''This guide outlines a systematic approach to development of laboratory accelerated weathering tests of building sealant systems including the identification of needed information, the development of accelerated tests, the application of data, and the reporting of results.

1.3''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.
