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

This makes this practice suitable for flat panels as well as large or 3D objects. Referenced Documents purchase separately The documents listed below are referenced within the subject standard astm d2247 are not provided as part of the standard. 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 astm d2247 are used to astm d2247 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 for example, water spray.

The values given astm d2247 parentheses are astm d2247 information only. This makes this practice suitable for flat panels as well as large or 3D objects. Some tests are used for a pass or fail determination at an arbitrary time.

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, but the back surface astm d2247 outside the exposure area. Users of this practice alone may use the astm d2247 performance of the controls to astmm test end points.

Other tests may also deposit water astm d2247 on the surface but where the source is not from condensation. It is the responsibility of the user of this standard to establish appropriate astn and health astm d2247 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 d224 a way to differentiate performance. It does not specify specimen preparation, or evaluation of results.

Note 1—Alternative practices for testing the water resistance of coatings include Practices DD astm d2247, d2427 Astm d2247 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.

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

This practice is therefore useful for evaluating coatings alone or complete coating systems. Link to Active This link astm d2247 always route to the current Active version of the standard.
