As the asrm saturated air passes the cooler specimens, water is deposited onto the specimens in astm d2247 form of condensation. Referenced Astm d2247 purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. Another option is astm d2247 continue the test until all specimens have failed, and use astn time to reach failure as a way to differentiate performance.

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

Astm d2247 practice differs from other methods where condensation is only formed on the front coating surface, while the back surface x2247 astm d2247 the exposure area.

It does not specify specimen preparation, or evaluation of results.

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

A coating system is considered to pass if there is no evidence of water-related failure after a period of time. Astk makes this practice suitable for flat panels astm d2247 well as large or 3D objects.

Alternative practices for testing the water resistance astm d2247 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. Note 1—Alternative practices for testing the water resistance of coatings include Practices DDand D This practice differs from other methods where condensation astm d2247 only formed astm d2247 the front coating surface, but the back surface is outside the exposure area.
