Alternative practices for testing the water resistance of coatings include Practices DDand D Corrosion tests can be conducted, as the condensate dripping off the test articles in not recirculated.

The values given in parentheses are for information only.

Other tests may also deposit water droplets on the surface but where the source is not from condensation for example, water spray. It is the responsibility of the user of this standard to establish appropriate safety and health practices and axtm the applicability of regulatory limitations prior to use.

Another option is to continue the test until all specimens have failed, and use the e2247 to reach failure as a way to differentiate performance. Other tests are used to monitor degree of failure as a function of exposure time. The values given in parentheses are for information only. As the warmer saturated air passes the cooler specimens, water is deposited onto the specimens in the form of condensation.

Some tests are used for a pass or fail determination at an arbitrary time. Other tests may also deposit water droplets on the surface but where the source is not from condensation.

Users of this practice alone may use the known performance of the controls to set test end points. This makes this practice suitable for flat panels as well as large or 3D objects.

This practice differs from other methods where condensation is only formed on the front coating surface, but the back surface is outside the exposure area. Note 1—Alternative practices for testing the water resistance of coatings include Practices DDand D This practice differs from other methods where condensation is only formed on the front coating surface, while the back surface is outside the exposure area.

It does not specify specimen preparation, or evaluation of results. A coating system zstm considered to pass if there is no evidence of water-related failure after a period of time. Historical Version s – view previous versions of standard.
