ASTM D 7376 : 2010

CONTAINED IN VOL. 06.02, 2017 Describes the resistance to corrosion and blistering of coil-coated metal products relative to one another when stacked outdoors under direct weathering conditions in which they are wetted by rain and dew.

1.1 This procedure describes the practice for determining relative performance of coil-coated metal in an outdoor wet stack testing environment.

1.2 The purpose of this test is to evaluate relative wet stack corrosion resistance and blistering. Substrates, pretreatments, primers, topcoats, and backers may be evaluated.

1.3 This test simulates coil or stacked building panel bundle storage at a job site in wet outdoor conditions. The results from panels tested during the same time period may be used to compare products as an indicator of actual field performance. Environments with higher temperature and moisture levels accelerate degradation.

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

1.5 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 determine the applicability of regulatory limitations prior to use.
