BS EN 13966-1:2003 PDF

Scope: This European Standard specifies a laboratory procedure for determining the transfer efficiency of atomising and spraying equipment for the application of liquid coating materials onto flat panels. A second part (to be prepared) will cover coating material application to other substrate geometries and provide a method for the determination of transfer efficiency for atomising and spraying equipment with electrostatic support. This standard applies to the determination of the transfer efficiency of atomising and spraying equipment, such as, but not limited to: — conventional air atomiser (high air pressure); — HVLP-atomiser (high volume low pressure); — LVLP-atomiser (low volume low pressure); — airless atomiser (hydraulic pressure); — air assisted airless atomiser; — vibratory or rotary atomiser (bells); — electrostatic supported atomiser. Two methods of determination are included in the standard. The transfer efficiency value resulting from the application of this standard procedure expresses the potential performance of atomising and spraying equipment for comparison of different types or models. The value may or may not be attained in use, where the working conditions and operator practice are likely to differ from those of the standard test method. The determined transfer efficiency is valid only in conjunction with the parameters shown in the test summary form, see annex C.
