5、standard includes safety requirements. This standard has been prepared by Technical Committee CEN/TC 271, “Surface treatment equipment Safety” (Secretariat: DIN, Germany). The responsible German body involved in its preparation was the Normenausschuss Maschinenbau (Mechanical Engineering Standards C

6、ommittee), Working Committee NA 060-09-44 AA Lacktrockner und thermische Abluftreinigung of Section Oberflchentechnik. Representatives of manufacturers and users of thermal cleaning systems for exhaust gas, and of the employers liability insurance associations contributed to this standard. This stan

7、dard contains specifications meeting the essential requirements set out in Annex I of the new “Machinery Directive”, Directive 2006/42/EC, and which apply to machines that are either first placed on the market or commissioned within the EEA. This standard serves to facilitate proof of compliance wit

8、h the essential requirements of the directives. Once this standard is cited in the Official Journal of the European Union, it is deemed a “harmonized” standard and thus, a manufacturer applying this standard may assume compliance with the requirements of the Machinery Directive (“presumption of conf

9、ormity”). The European Standards referred to in Clause 2 and in the Bibliography of the EN have been published as the corresponding DIN EN or DIN EN ISO Standards with the same number.

30、O 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 standards, the provisions of this type C

31、 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. DIN EN 12753:2011-02 EN 12753:2005+A1:2010 (E) 5 1 Scope 1.1 This European Standard is applicable to thermal cleaning systems fo

32、r 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 concentration ranges given in 5.2.2.

33、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 equipment (e.g. barrels, tins, cans or co

34、ntainers); 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 by the manufacturer.“ The types of the

35、rmal 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 this European Standard a thermal cle

36、aning 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, predominantly volatile organic compounds,

37、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. 1.3 This European Standard is not a
