By design this guide does not purport to address test methods or procedures developed specifically for the functional powder coating market, those coating powders for application to pipe or reinforced steel bars rebar.

Large area view is also recommended whenever possible.

No other units of measurement are included in this standard. There is no consistent correlation between the two tests.

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.

Failure, when it occurs, is usually in the form of discoloration, changes in gloss, blistering, softening, swelling, or loss of adhesion. For example, the appliance industry has developed accelerated tests to simulate the long term service exposure of range stove components to heat cycles or food soils, or both. Where more than one test method is listed for the same d34511, no attempt is made to indicate superiority of one method over another.
