BS EN 12921-1:2005+A1:2010EN 12921-1:2005+A1:2010 (E) 5 Introduction This European Standard is a type C standard as stated in EN ISO 12100. The machinery concerned and the extent to which hazards, hazardous situations and events are co

26、vered 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 standard take precedence over the provisions of the other standards, for machines that have been desig

27、ned and built according to the provisions 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 ma

29、d equipment for automated and manual cleaning 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 si

30、ngle-zone or multi-zone machine, chamber 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 othe

31、r mechanical system of agitation, recirculation 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

32、to be processed; product handling systems 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 indus

33、trial items using liquids or vapours when 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 comm

34、on devices and should be used in connection 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 par

35、t of this document, part 1 of EN 12921 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 cl

36、eaning liquids; prEN 12921-4 for halogenated solvents. 1.3 !

37、 to EN 50416, surface cleaning employing liquids according to EN 60335-2-54, commercial electric dishwashing according to EN 60335-2-58, cleaning with high pressure and steam according to EN 60335-2-79, plasma cleaning, mechanical blasting, thermal cleaning, drying processes, cleaning of textiles or

38、 clothes, food processing. This standard is not applicable to the following equipment: loading and unloading systems, automatic systems, e.g. robots as covered by EN ISO 10218-1, centrifuges as covered by EN 12547, pumps and pump units for liquids as covered by EN 809.“ 1.4 This standard is not appl
