This EN specifies a laboratory procedure for determining the transfer efficiency of atomising and spraying equipment for the application of liquid coating materials onto flat panels. This standard applies to determination of the transfer efficiency of atomising and spraying equipment, such as: - air atomising spray guns (conventional high air pressure); - high volume low pressure spray guns (HVLP); - low volume low pressure spray guns (LVLP); - airless spray guns (hydraulic pressure); - air assisted airless spray guns; - vibratory or rotary atomising atomising equipment (bells or discs); etc.

This European Standard applies to the design and construction of spraying equipment for both manual and automatic application of liquid, paste (semi-solid) and powder coating materials. The manual equipment is hand-held and the automatic equipment is operated by auxiliary signals and mounted either rigidly or onto automated devices such as robots, or reciprocating or rotary machines.
The coating material may be atomised by air, by airless, by airless with the assistance of air or mechanically by centrifugal force. With atomisation by centrifugal force, the atomised coating material may be assisted towards the workpiece by controlled air veils.
The atomising and spraying equipment may also be electrostatically supported.
This standard specifically refers to hazards created by or resulting from the use of atomising and spraying equipment, if it is used as determined and in accordance with the foreseeable conditions of the manufacturer (see clause 4).
Atomising and spraying equipment may be linked with supply systems, control circuits, spray booths and/or automated machinery, none of which are covered by the scope of this standard. This may result in the overlapping of some hazards or risks. Such hazards or risks should be taken into consideration when specifying and installing the atomising and spraying equipment.
Further topics for this standard are minimum user information:
-   Operation manuals,
-   Marking.
This standard excludes:
-   Flocking machines;
-   Equipment related to the atomising and spraying of foodstuffs and pharmaceuticals;
