This document (EN 1953:2013) has been prepared by Technical Committee CEN/TC 271 “Surface treatment equipment Safety” (Secr

5、etariat: DIN, Germany). The responsible German body involved in its preparation was the Normenausschuss Maschinenbau (Mechan-ical Engineering Standards Committee), Working Committee NA 060-09-42 AA Beschichtungsgerte und Materialversorgung of Section Oberflchentechnik. Representatives of manufacture

6、rs and users of machinery for the supply and circulation of coating materials, and of the employers liability insurance associations contributed to this standard. This standard contains specifications meeting the essential requirements set out in Annex I of the “Machinery Directive”, Directive 2006/

7、42/EC, and the ATEX Directive 94/9/EC, and which apply to atomising and spraying equipment for coating materials that are either first placed on the market or commissioned within the EEA. This standard serves to facilitate proof of compliance with the essential requirements of that directive. Once t

8、his standard is cited in the Official Journal of the European Union, it is deemed a “harmonized” stand-ard and thus, a manufacturer applying this standard may assume compliance with the requirements of the Machinery Directive and the ATEX Directive (“presumption of conformity”). The European Standar

9、ds 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. Where the International Standards referred to are not also DIN ISO Standards with the same number, there are no national standards available. Ame

10、ndments This standard differs from DIN EN 1953:2010-09 as follows: a) Clause 1 “Scope” 1) it has been clarified that the specific significant risks related to the use of atomising and spraying equipment with foodstuffs and pharmaceutical products are not dealt with in this standard; b) Clause 2 “Nor

11、mative references” 1) normative references have been updated; c) Clause 5 “Safety requirements and/or measures” has been rendered more precise, in particular with regard to 1) insufficient mechanical strength (5.2.2) 2) ejection of fluids (5.2.3) 3) ejection of material or objects (5.2.4) 4) thermal

12、 effects (5.4) 5) noise (5.5) 6) explosion (5.6) 7) dangerous substances (5.7) 8) malfunction (5.9) DIN EN 1953:2013-12 3 d) ergonomic requirements (5.8) e) Clause 7 “Information for use” 1) the relevant requirements have been rendered more precise 2) the requirements for marking have been rendered

13、more precise f) Annex ZA (informative) “Relationship between this European Standard and the Essential Requirements of EU Directive 2006/42/EC” has been updated; g) Annex ZB (informative) “Relationship between this European Standard and the Essential Requirements of EU Directive 94/9/EC” has been inc
