ASTM C732-17 PDF Download

The ASTM C732-17 standard outlines a laboratory procedure for evaluating the impact of artificial weathering on latex sealants. The goal of this test is to determine the long-term exterior durability of the sealant when used with wood or aluminum.

The standard specifies that accelerated weathering exposure is used to simulate the effects of extended outdoor exposure on the sealant. It emphasizes the importance of understanding how the sealant will perform in different environmental conditions and serves as a benchmark for assessing its durability.

The standard also includes important information regarding the units of measurement. It states that metric (SI) units should be used as the standard, while values in parentheses are provided for reference purposes only. This ensures consistency in reporting and comparison of results.

It is worth noting that, as of now, there is no ISO standard equivalent to this ASTM test method. This highlights the unique contribution of ASTM C732-17 in evaluating the aging effects of artificial weathering on latex sealants.
