scope:

1.1 This practice offers guidelines for selecting wood or wood composite substrates for the evaluation of specific weathering performance characteristics of architectural coatings such as exterior paints, primers, and deck finishes.

1.2 Procedures include selecting wood species and choosing individual wood test panels through visual examination of the wood characteristics.

1.3 This practice is intended to cover the most commonly employed wood substrates used in weathering studies of architectural coatings. It is not intended to serve as a comprehensive guide for all wood species that may be employed for the purpose of evaluating weathering performance characteristics of architectural coatings.

1.4 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system are not necessarily exact equivalents; therefore, to ensure conformance with the standard, each system shall be used independently of the other, and values from the two systems shall not be combined.

1.5 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.

1.6 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.
