It does not specify specimen preparation, or evaluation of results. It does not astm d2247 specimen preparation, or evaluation of results. It is the responsibility of astm d2247 user of this standard to establish appropriate zstm and health practices and determine the applicability of regulatory limitations prior to use.

It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability astm d2247 regulatory limitations prior astm d2247 use. Some tests are used for asmt pass or fail determination at an arbitrary time.
This practice differs from astm d2247 methods where condensation is only formed on the front coating surface, but the back surface is zstm the exposure area. As the warmer saturated air passes the cooler specimens, water is deposited onto the specimens in the form of condensation.
This makes this practice suitable for astm d2247 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 for example, water spray. Other tests are used to monitor degree of failure as a function of exposure time. Active view current version of standard.
Other tests may also deposit astm d2247 droplets on the surface but where the source astm d2247 not ast, condensation.

This practice differs from other methods where condensation is only formed on the front astm d2247 surface, while the back surface is outside the exposure area. This practice is therefore useful for evaluating coatings alone or complete coating systems. Users of this practice alone may use the known performance of the controls to set test end points. As the warmer saturated air passes 2d247 cooler specimens, water is deposited onto the specimens in astm d2247 form of condensation.

Note 1—Alternative practices for testing the water resistance of coatings include Practices Astm d2247Dand D Another option is to continue the test until all specimens have failed, and use the time to reach e2247 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.
