This document is applicable to spray booths as well as multizone spray booths for the application of organic liquid coating materials (paints, varnishes....), and deals with all significant hazards relevant to spray booths or multizone spray booths, when they are used as intended and under the conditions foreseen by the manufacturer (see clause 4).
A spray booth is an assembly of the following linked components: forced ventilation by one or more fans; dry air filtering and/or wet air washing systems, measuring and control devices, ventilation air heating system, automatic fire extinguishing equipment, warning devices, electrical apparatus, joined together within or at a partially or totally enclosed structure (limited by walls, called space) for the controlled processing of spray application of organic liquid coating material.
NOTE   Spray booths are classified in annex G.
This standard describes methods of verification of safety measures, information labels to be affixed to the spray booth and minimum usage requirements contained within the operators handbook.
This standard does not cover:
-   spraying areas (spaces for application of organic liquid coating materials which are limited only by one side wall used for extraction of exhaust ventilation).
-   combined spray booths according to definition given in 3.2;
NOTE   See prEN 13355.
-   the limiting walls of spray booths if they are constituent parts of a building are not to be considered part of the machinery assembly;
-   the workroom or building used for the spraying of large size items (example: air-liner);
-   spraying equipment used in spray booths which is covered by EN 1953, EN 50050, and EN 50176.
-   Spray booths which are part of complex installations.
NOTE   complex installations may include additional hazards.
This standard is not applicable to spray boots which are manufactured before the date of publication of this standard by CEN.

This standard 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 such as but not limited to
¾ machines for cleaning and pretreatment of industrial item surfaces,
¾ machinery for coating and colour mixing,
¾ coating plants
and
¾ dryers, ovens and evaporating equipment.
This standard 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 pretreatment 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 standard, the measurement for very large machines is simplified by determining an averaged emission sound pressure level instead of the sound power level.
This standard specifies noise measurement methods, installation/mounting and operation conditions that shall be used for the test. The use of this standard 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 standard are engineering methods (grade 2) and survey methods (grade 3).
