If the document is revised or amended, you will be notified by email. Impact resistance has also been found to be a good indication of whether a coating powder has been adequately cured.

Standard – Standard Guide for Testing Coating Powders and Powder Coatings ASTM D –

It should be noted that many of the methods used for characterizing a coating powder, such as gel time Section 16 and inclined flow Section 17are primarily meant for the relative comparison of two coating powders, rather than to give a test value that can be interpreted as good or bad.

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.

Xenon arc exposure produces temperature differences between dark and light color that is similar to those in outdoor exposure. Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend. The comparison of results are only valid for coating powders tested in the same laboratory at about the same time, not results between different laboratories.


Do not use abrasives to clean the bar. Interpretation of the test results will depend on the specific application in question and will also often depend on the chemistry of the coating powder used.

The cured weight loss may be requested in order to properly determine the exhaust requirements of a bake oven or to comply with state or federal reporting guidelines. Brush the material towards the lower temperature and note the location where particles of powder adhere to the bar when brushed lightly.
