The attention of the reader is drawn to the fact that compliance with this European Standard does not waive the obligation to comply with the regulations governing installations categorised for environmental protection which also deal with the risks of nuisance to
22、the surroundings such as noise emitted outside the building, odours, pollution. NOTE Although a thermal cleaning system, as an integral whole, formally does not fall under the scope of the ATEX Directive 94/9/EC, the standard is based upon a fundamental risk analysis according to this directive.

25、type C standard as stated in EN ISO 12100. The machinery concerned and the extent to which hazards, hazardous situation and events are covered are indicated in the scope of this European Standard. When provisions of this type C standard are different from those which are stated in type A or B standa
26、rds, the provisions of this type C standard take precedence over the provisions of the other standards, for machines that have been designed and built according to the provisions of this European Standard.

27、icable 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 within the
28、 concentration ranges given in 5.2.2.2. 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 equi
29、pment (e.g. barrels, tins, cans or containers); related solvent handling equipment. !This European Standard deals only with the significant hazards from fire and explosion and hazards generated by residual process gases as listed in Clause 4, when used as intended and under the conditions foreseen b
30、y the manufacturer.“ The types of thermal cleaning systems covered in this European Standard are direct combustion, and catalytic combustion (see definitions in 3.1.1 and 3.1.2). This European Standard applies in conjunction with the relevant requirements of EN 746-1 and EN 746-2. For the purpose of
31、 this European Standard a thermal cleaning system for process gas contains the following components: fan(s), heat exchanger, process space, main and supporting burner, injection system, power driven dampers, control and power circuits joined together for the processing of flammable substances, predo
32、minantly volatile organic compounds, by effecting oxidation. NOTE Thermal cleaning equipment is usually integrated with systems as covered by e.g. EN 1010-1, EN 1539, EN 12215, EN 12921-1 or EN 12921-3. 1.2 This European Standard is not applicable to: thermal paint removal systems; pyrolytic systems
