ÖNORM EN 14462

This document specifies all the information necessary to carry out efficiently and under standardised conditions the determination, declaration and verification of the airborne noise emission of surface treatment machines as stated in Annex A. Surface treatment machines include but are not limited to machines for cleaning and pre-treatment of industrial item surfaces, machinery for coating and colour mixing, coating plants and dryers, ovens and evaporating equipment. This document describes the determination of emission sound pressure levels at work stations or other specified positions as well as the determination of sound power levels for surface treatment machines as stated in Annex A. This can be small single units (e.g. handheld atomising spraying equipment) and also complex machines with large dimensions (e.g. machines for cleaning and pre-treatment of industrial item surfaces, spray booths, dryers), which could also be linked. In case of very large machines as defined in 3.10 the determination of sound power level may be very complicated or cannot be done with a reasonable amount of work. Therefore in this document, the measurement for very large machines is simplified by determining an averaged emission sound pressure level instead of the sound power level. This document specifies noise measurement methods, installation/mounting and operation conditions that shall be used for the test. The use of this document ensures the reproducibility of the determination of the noise emission characteristics within specified limits determined by the grade of accuracy of the basic noise measurement method used (see 5.1 and 6.1). Noise measurement methods allowed by this document are engineering methods (grade 2) and survey methods (grade 3). For continuous flow dryers for paper, board and foil (see EN 13023).
