Standard Test Method for Accelerated Weathering of Solvent-Release-Type Sealants

Importancia y uso:

5.1 It is difficult to establish a precise correlation between laboratory accelerated and natural weathering because of (1) geographical climatic variations, local weather variation from normal, and local pollutants and (2) the fact that the acceleration factor is material dependent, varying with the type of material as well as its formulation. This test method is used to determine the resistance of a sealant to laboratory accelerated weathering and, if a control material with known outdoor weathering performance is used, the relative weathering performance of the sealant against that of the control material.

5.2 This test method is conducted using aluminum channels. Other substrate materials may show different results.
