1. Scope

1.1 This practice describes outdoor exposure procedures used to determine the weathering durability of building construction, seals and sealants.

Note 1See Practice G 24 for Exposures to Daylight Filtered Through Glass.

1.2 This practice is limited to the method by which the construction seals or sealants are exposed to outdoor weathering as part of a test program. It does not describe the test methods to be performed following the outdoor exposure. It is intended for specimens of any size and shape to be used in static or dynamic tests.

1.3 Means of evaluation of the effects of weathering will depend on the intended use for the test material.

1.4 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.

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 and health practices and determine the applicability of regulatory limitations prior to use.
