This standard has been prepared by Technical Committee CEN/TC 271 “Surface treatment equipment Safety” (Secretaria

6、t: DIN, Germany). The responsible German body involved in its preparation was the Normenausschuss Maschinenbau (Mechanical Engineering Standards Committee), Working Committee NA 060-09-41 AA Vorbehandlungs-anlagen of Section Oberflchentechnik. Representatives of manufacturers and users of machines f

7、or surface cleaning and pre-treatment, 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 2006/42/EC, and which apply to machines that

8、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 the directives. Once this standard is cited in the Official Journal of the European Union, it is deemed a “harmonized” standard and thus, a

9、manufacturer applying this standard may assume compliance with the requirements of the Machinery Directive (“presumption of conformity”). The European Standards referred to in this document have been published as the corresponding DIN EN or DIN EN ISO Standards with the same number. Where the Intern

10、ational Standards referred to are not also DIN ISO Standards, there are no national standards available, except for the following: ISO 3864-1:2002 DIN 4844-1:2005, mod. Amendments This standard differs from DIN EN 12921-1:2005-08 as follows: a) Subclause 1.3 has been updated; b) Clause 5 “Safety req

11、uirements and/or measures” has been suplemented; c) Clause 7 “Information for use” has been revised; d) Annex A “National references to exposure limit values” has been updated; e) Annex ZA (informative) “Relationship between this European Standard and the Essential Requirements of EU Directive 2006/

The machinery concerned and the extent to which hazards, hazardous situations and events are covered are indicated in the scope of

33、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 standard take precedence over the provisions of the other standards, for machines that have been designed and built according to the provi

34、sions of this type C standard. This European Standard consists of the following parts: Part 1: Common safety requirements Part 2: Safety of machines using water based cleaning liquids Part 3: Safety of machines using flammable cleaning liquids Part 4: Safety of machines using halogenated solvents DI

35、N EN 12921-1:2011-02 EN 12921-1:2005+A1:2010 (E) 6 1 Scope 1.1 This standard applies to machines for surface cleaning and pre-treatment in the following called “cleaning machines“ of industrial items using liquids or vapours, i.e. stationary machines and related equipment for automated and manual cl

36、eaning and pre-treatment processes. NOTE Cleaning machines are operated with or without heating, for example as dipping or spraying or vapour condensation process, where additional using of ultrasound is possible. These cleaning machines could be designed as single-zone or multi-zone machine, chambe

37、r machines, drum cleaning machine, low lift truck machines, round time machines or tunnel (continuous) machines. To the extent of this document, cleaning machines for industrial items are considered as an assembly of the following equipment: pump(s) and/or other mechanical system of agitation, recir

38、culation and spraying of cleaning liquid; forced ventilation system; heating system with temperature control; condensation system; filtration and separation system and/or solid particles extraction from the liquid; conveyor and/or handling system for the items to be processed; product handling syste

39、ms and reciprocators which are part of the cleaning machine; control and/or monitoring systems; liquid handling system. 1.2 This European Standard deals with the common significant hazards, hazardous situations and events relevant to cleaning machines for industrial items using liquids or vapours wh

40、en they are used as intended and under the conditions foreseen by the manufacturer (see clause 4). This part of the standard defines the common safety requirements for all kinds of cleaning machines for industrial items using liquids or vapours and related common devices and should be used in connec

41、tion with other parts of the EN 12921-series. The specific requirements specified in part 2 and following parts of EN 12921 take precedence over the respective requirements in EN 12921. NOTE In addition, where a cleaning machine is not covered by a specific part of this document, part 1 of EN 12921

42、can be used to establish the approach for dealing with the relevant risks. Specific hazards which are related to the type of cleaning liquid used are dealt with in the following documents: EN 12921-2 for water based cleaning liquids; EN 12921-3 for flammable cleaning liquids; prEN 12921-4 for haloge

43、nated solvents. 1.3 !
