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.
