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

Water Resistance and Humidity (ASTM D 870, ASTM D 2247)

Active view current version of standard. Users of this practice alone may use the known performance of the controls to set test end points.

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

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. Note 1—Alternative practices for testing the water resistance of coatings include Practices DDand D As the warmer saturated air passes the cooler specimens, water is deposited onto the specimens in the form of condensation.

This practice differs from other methods where condensation is only formed on the front coating surface, but the r2247 surface is outside the exposure area.

This makes this practice suitable for flat panels as well as large or 3D objects. The values given in parentheses are for information only.

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. This makes this practice suitable for d22247 panels as well as large or 3D objects. Other tests are used to monitor degree of failure as a function of exposure time. Other tests may also deposit water droplets on the surface but where the source is not from condensation.
