1.1''This test method describes the determination of the structural performance of exterior windows, doors, skylights, and curtain walls under cyclic air pressure differential, using a test chamber. This test method is applicable to all curtain wall assemblies, including, but not limited to, metal, glass, masonry, and stone components.2

1.2''This test method is intended only for evaluating the structural performance associated with the specified test specimen, and not the structural performance of adjacent construction.

1.3''Procedure A shall be used for life cycle test loads.

1.4''Procedure B shall be used for wind event test loads.

1.5''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.

1.6''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. Specific hazard statements are given in Section 7.

1.7''The text of this test method references notes and footnotes that provide explanatory materials. These notes and footnotes (excluding those in tables and figures) shall not be considered as requirements of the standard.

1.8''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.
