Other tests astm d2247 also deposit water droplets on the surface but where the source is not astm d2247 condensation for example, water spray. It does not specify specimen preparation, or evaluation of results.

It is the responsibility of the user of this standard to satm appropriate safety and health practices and 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, while the back surface is outside the exposure area. The values given in parentheses are for information only. astm d2247

Other tests are used to monitor degree of failure as a function of exposure astm d2247. Some tests are used for a pass or fail determination at an arbitrary time.
