scope:

1.1 This test method covers the determination of the structural performance of dimension stone cladding systems under positive and negative uniform static air pressure differences, using a test chamber.

1.2 The proper use of this test method requires a knowledge of the principles of pressure and deflection measurement.

1.3 This test method describes the apparatus and the procedure to be used for applying either specific test loads or unknown ultimate values of uniformity distributed test loads to a specimen.

1.3.1 Procedure A (see 11.2) shall be used when deflections at maximum load only are required.

1.3.2 Procedure B (see 11.3) shall be used when a load-deflection curve is required.

1.4 The values stated in inch-pound units are to be regarded as the standard. The SI (metric) units given in parentheses are for information only and may be approximate.

1.5 This standard does not purport to address all of the safety problems, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. For specific precautionary statements, see Section 7.
