ASTM D7376-10a(2016)

1.1This practice is used to determine 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.

1.2The coil-coated product variables evaluated may include, but are not limited to, substrates, pretreatments, primers, topcoats, and backers.

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

1.4This standard does not endorse the storage of level (that is, 0° from horizontal) building panels stacks in wet outdoor conditions. Level storage of building panels is not recommended and is used in this standard for evaluation only.

1.5The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.

1.6This 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.
