2、the case of revision,the year of last revision.A number in parentheses indicates the year of last reapproval.Asuperscript epsilon()indicates an editorial change since the last revision or reapproval.1.Scope1.1 These test methods cover the determination of thetransfer efficiency of spray-applied coat
3、ings under generalplant conditions.Transfer efficiency is the ratio of paint solidsdeposited to the total paint solids used during the applicationprocess,expressed as a percent.1.2 The transfer efficiency is calculated from the weight orvolume of the paint solids sprayed and that of the paint solids
4、deposited on the painted part.1.3 Limitations include the ability to accurately determinethe amount of paint solids deposited on the part and thecapability of accurate measurement of the amount of paintsprayed.1.4 The values stated in SI units are to be regarded as thestandard.The values given in pa
