Significance and Use | ||||||||||||
5.1 Subject to the limitations listed in 1.1 This practice covers the evaluation and comparison of the transfer efficiency of spray-applied coatings under general laboratory conditions. Transfer efficiency is the ratio of paint solids deposited to the total paint solids used during the application process, expressed as a percent. This practice can be used to study the effect on transfer efficiency of changing operating variables and paint formulations. Key variables that need to be controlled are listed in 1.2 The reproducibility of this practice is highly dependent on the degree of control of the parameters listed in Section 8 of the practice. 1.3 Limitations—This laboratory practice indicates only the direction of the effect of operating variables and liquid paint formulations on transfer efficiency under conditions of the laboratory test: the magnitude of the effect can be determined only with specific plant experience. In fact, the nature of the critical parameters that affect transfer efficiency makes clear that it is not possible to extrapolate laboratory results. 1.4 The values stated in SI units
are to be regarded as the standard. The values given in parentheses
are for information only.
1.5 This standard does not
purport to address all of the safety concerns, if any, associated
with its use. It is the responsibility of the user of this standard
to establish appropriate safety and health practices and determine
the applicability of regulatory limitations prior to use.
