25、 is held by DIN. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by April 2016, and conflicting national standards shall be withdrawn at the latest by April 2016.

26、9. This document has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association, and supports essential requirements of the EU Directive 2006/42/EC. For relationship with the EU Directive, see informative Annex ZA, which is an integral part of this

27、document. This European Standard is part of a series of standards in the area of safety for development and construction of machines and plants for the coating of surfaces with organic substances (paints, lacquers and similar products). This European Standard was prepared with contribution of the fo

28、llowing TCs: TC 186 “Industrial thermoprocessing - Safety“; TC 198 “Printing and paper machinery - Safety“; TC 200 “Tannery machinery - Safety“; TC 202 “Foundry machinery“. NOTE 1 Although a dryer as a whole is not subject to the ATEX Directive 94/9/EC in a formal way, this document is based on a fu

29、ndamental risk assessment according to this Directive. NOTE 2 This European Standard is based on an explosion protection concept which does not define zones for areas with potentially explosive atmosphere. In relation to the previous version of the standard, the following main modifications have bee

30、n made the scope has been adjusted to meet the fields of application of the standard; the requirements for safety related controls have been modified for clarification; guidance for implementation of safety related control systems has been included; requirements for monitoring of heating system have

31、 been implemented; requirements for type B dryers have been detailed; requirements for minimization of energy usage and environmental impact have been included.

This document is of relevance in particular for the following stakeholder group representing the market players with regard to machinery safety: machinery manufacturers

35、(small, medium and large enterprises); health and safety bodies (regulators, accident prevention organisations, market surveillance). The machinery concerned and the extent to which hazards, hazardous situations and hazardous events are covered are indicated in the scope of this European Standard. W

36、hen 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 standard take precedence over the provisions of the other standards, for machines that have been designed and built according to the provisions of this type C stan

37、dard. BS EN 1539:2015EN 1539:2015 (E) 8 1 Scope This European Standard deals with all significant hazards, hazardous situations and hazardous events relevant to ovens and dryers in which flammable substances are released by evaporation from and curing of coating materials. The specific significant r

38、isks related to the use of this machinery with foodstuff and pharmaceutical products are not dealt with in this European Standard. This European Standard is only applicable to machines which are used as intended and under the conditions which are foreseeable as malfunction by the manufacturer (see C

39、lause 4). For ovens and dryers in which flammable substances are released by evaporation from and curing of coating materials, in which the concentration of these flammable substances shall not, under no circumstances, exceed 3 % of the LEL, EN 746-1 and EN 746-2 may be applied instead of this Europ

40、ean Standard. This European Standard is not applicable to: ovens for hardening metals; enamelling plants; portable heating systems for drying (for instance infrared radiant heaters, hot-air blowers, blow-dryers); solvent recovery plants; distillation and/or refraction plants; textile dry-cleaning sy

41、stems. This European Standard is not applicable to machinery manufactured before the date of its publication as EN. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.
