BS EN 12753:2005+A1:2010 Thermal cleaning systems for exhaust gas from surface treatment equipment. Safety requirements
BS EN 12753 is a European Standard which applies to thermal cleaning systems for exhaust gas from surface treatment equipment/systems as given below in which the concentration of exhaust gas to be cleaned (for the purpose of this European Standard, named "process gas") at the inlet to the thermal cleaning system is safely limited.
Surface treatment equipment includes:
- Dryers according to EN 1539, curing equipment;
- Flash-off areas;
- Coating plants (e.g. closed spray booths, open fronted spray booths);
- Machines using flammable solvents for the pre-treatment and cleaning of products or
- equipment (e.g. barrels, tins, cans or containers);
- Related solvent handling equipment.
BS EN 12753 deals only with the significant hazards from fire and explosion and hazards generated by specific residual process gases, when equipment is used as intended and under the conditions foreseen by the manufacturer.
The types of thermal cleaning systems covered in this European Standard are
- Direct combustion, and
- Catalytic combustion
BS EN 12753 is not applicable to:
- Thermal paint removal systems;
- Pyrolytic systems.
BS EN 12753 is not applicable to thermal cleaning systems which are manufactured before the date of publication of this document by CEN.
