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. 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.

This practice is therefore useful for evaluating coatings alone or complete coating systems.

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

As d2247 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. As the warmer saturated air passes the cooler specimens, water is deposited onto the specimens in the form of condensation. Other tests are used to monitor degree of failure as a function of exposure time.

This makes this practice suitable for flat panels as well as large or 3D objects. This makes this practice suitable for flat panels as well as large or 3D objects.

Another option is to d227 the test until all specimens have failed, and use the time to reach failure as a way to differentiate performance.

Historical Version s – view previous versions of standard. It does not specify specimen preparation, or evaluation of results. Corrosion tests can be ast, as the condensate dripping off the test articles in not recirculated. A coating system is considered to pass if there is no evidence of water-related failure after a period of time.
