1.1 This practice covers specific procedures and test conditions that are applicable for exposure of plastics in enclosed carbon-arc devices conducted in accordance with Practices G151 and G153. This practice also covers the preparation of test specimens, the test conditions suited for plastics, ...

1.1 The resistance of plastics to breakage by flexural shock may be determined by test methods such as those contained in Test Method D 256. Specimens used in those test methods feature a milled notch to promote brittle fracture. The test specimens are struck by a pendulum with the depth dimensio...

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 val...

1.1 This test method covers a laboratory procedure for determining the effects of accelerated weathering on cured-in-place elastomeric joint sealants (single- and multicomponent) for use in building construction.

1.2 The values stated in SI units are to be regarded as the standard. The valu...

1.1 This guide covers elementary statistical methods for the analysis of data common to weathering experiments. The methods are for decision making, in which the experiments are designed to test a hypothesis on a single response variable. The methods work for either natural or laboratory weatheri...
