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

Summary of Test Method

This test method consists of sealing the test specimen into or against once face of a test chamber, supplying air to or exhausting air from the chamber according to a specific test loading program, at the rate required to maintain the test pressure difference across the specimen, and observing, measuring, and recording deflection, deformations, and nature of any distress or failures of the specimen.

Significance and Use

This test method is a standard procedure for determining structural performance under uniform static air pressure difference.  This typically is intended to represent the effects of a wind load on exterior building surface elements.
