16、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.NOTE 1The method described in this part of ISO 8130 is a simple, practical test which provides sufficiently accurate results with coating
17、 powders that lose up to about 2 % (m/m) on stoving. Above this, accuracy decreases with increasing loss in mass.NOTE 2Any water present in the product under test is included in the test result.2 Normative referenceThe following standard contains provisions which, through reference in this text, con
18、stitute provisions of this part of ISO 8130. At the time of publication, the edition indicated was valid. All standards are subject to revision, and parties to agreements based on this part of ISO 8130 are encouraged to investigate the possibility of applying the most recent edition of the standard
