ASTM C1442-99 - 10.8.1999
 
1. Scope

1.1 This practice covers three artificial weathering exposure procedures for evaluating the durability of sealants.

1.2 The three procedures are Practices G 152, G 154, and G 155.

1.3 The performance rankings of sealants provided by these procedures may not agree.

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

1.5 A related ISO procedure is ISO 11431. The user should compare to determine how procedures differ.

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