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

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

Other tests are used to monitor degree of failure as a function of exposure time. 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.

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.

A coating system is considered to pass if there is no evidence of water-related failure after a period of time. As the warmer saturated air passes the cooler specimens, water is deposited onto the specimens in the form of condensation.

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.

This practice f2247 therefore useful for evaluating coatings alone or complete coating systems. Some tests are used for a pass or fail determination at an arbitrary time. As the warmer saturated air passes the cooler specimens, water is deposited onto the specimens in the form of condensation.
