This part of ISO 8130 specifies a method for the determination of loss of mass on stoving of coating powders that are to be applied by electrostatic spraying on to a substrate. NOTES 1 The method described in this part of ISO 8130 is a simple, practical test which provides sufficiently accurate results with coating powders that lose up to about 2 % (m/m) on stoving. Above this, accuracy decreases with increasing loss in mass. 2 Any water present in the product under test is included in the test result.
