This makes this practice suitable for flat panels as well as large or 3D objects. As the warmer saturated air passes the cooler specimens, water is deposited onto the specimens in the form of condensation. The values given in parentheses are for information only. Historical Version s awtm view previous versions of standard. 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.

Other tests may also deposit water droplets on the surface but where the source is not from condensation for example, water spray.

As the warmer saturated air passes the cooler specimens, water is deposited onto the specimens in the form of condensation.

It does not specify specimen preparation, or evaluation of results. Other tests are used to monitor degree of failure as a function of exposure time.

Some tests are used for a pass or fail determination at an arbitrary time. A coating system is considered to pass if there is no evidence of water-related failure after a period of time.

The values given in parentheses are for information only. This practice is therefore useful for evaluating coatings alone or complete coating systems.

Corrosion tests can be conducted, as the condensate dripping off the test articles in not recirculated. 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 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.

Users of this practice alone may use the known performance of the controls to set test end points. It does not specify specimen preparation, or evaluation of results. Another option is to continue the test until all specimens have failed, and use the time to reach failure as a way to differentiate performance.
