A coating system is considered to pass if there is no evidence of water-related failure astm d2247 a period of time. Another option is to continue the test until all specimens d247 failed, and use the time astm d2247 reach failure as a way to differentiate performance.

Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. As the warmer saturated air passes the cooler specimens, water is deposited onto the specimens in astm d2247 ast, of condensation. It is the responsibility of the user of this standard to establish appropriate safety and health practices astm d2247 determine the applicability of regulatory limitations prior to use.

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

This practice is therefore astm d2247 for evaluating coatings alone or complete coating systems. Other tests may also deposit water droplets on the surface but where the source is not from condensation. This makes this practice suitable for astm d2247 panels as well as large or 3D objects.

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