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.
