ASTM C734-15 (R2019) PDF Download

The ASTM C734-15 (R2019) standard is a test method used to evaluate the low-temperature flexibility of latex sealants after artificial weathering. The standard specifies a laboratory procedure in which the latex sealants are subjected to 500 hours of artificial weathering. After the weathering process, the flexibility of the sealants is assessed in a low-temperature environment.

The purpose of this test is to determine how well the latex sealants maintain their flexibility after being exposed to artificial weathering. Flexibility is an important property of sealants as it ensures their ability to accommodate movements and remain effective in sealing joints under different environmental conditions.

This standard is intended to be used by manufacturers, researchers, and testing laboratories to assess the performance of latex sealants in terms of low-temperature flexibility. The values obtained from this test method are stated in metric (SI) units, with the values given in parentheses being for information purposes only. It is worth noting that currently, there is no ISO standard similar to this ASTM test method.
