3、ember 2013.1.Scope1.1 This test method covers procedures for determination ofthe transfer efficiency(using a weight method)under produc-tion conditions for in-plant spray application of automotivepaints as outlined in Section 18 of EPA 450/3-88-018.1.2 The transfer efficiency is calculated from the
4、weight ofthe paint solids sprayed and that deposited on the painted part.The recommended approach involves painting the part directly.Also described is an alternative approach for painting partscovered with aluminum foil.1.3 The values stated in SI units are to be regarded as thestandard.The values
