20、duction !This document is a type C standard as stated in EN ISO 12100. The machinery concerned and the extent to which hazards, hazardous situations and hazardous events are covered are indicated in the scope of this document. When provisions of this type C standard are different from those which ar
21、e 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 standard.“ 1 Scope This European Standard specifies safety requirements for
22、all the phases of the life of a machine listed in !5.3 a) of EN ISO 12100-1:2003“. Reciprocating roller machines are machines used for the processing of animal hides and skins. They have a reciprocating opening and closing motion of the feed rollers or conveyors which, if required, may also reverse
23、their direction. This standard covers the following reciprocating roller machines (see figures 1 to 13 for typical configurations and annex D for descriptions): a) Buffing machines (see figures 1a and 1b) b) Polishing machines (see figures 1a and 1b) c) Ironing machines (woolskins and fur) (see figu
24、res 2a and 2b) d) Carding machines (see figures 3a and 3b) e) Shearing machines (woolskins and fur) (see figures 4a and 4b) f) Cylinder universal staking machines (see figures 5a and 5b) g) Setting-out machines (see figures 6a and 6b) h) Dewooling machines (see figures 6a and 6b) i) Scudding machine
25、s (see figures 6a and 6b) j) Unhairing (dehairing) machines (see figures 6a and 6b) k) Sammying machines (see figures 6a and 6b) l) Cylinder ironing machines (see figures 7a and 7b) m) Cylinder staking machines (see figures 8a and 8b) n) Fleshing machines (see figures 9a and 9b) o) Demanuring machin
26、es (see figures 10a and 10b) BS EN 972:1998+A1:2010EN 972:1998+A1:2010 (E) 5 p) Wet wheeling machines (see figures 11a and 11b) q) Shaving machines (feed-out) (see figures 12a and 12b) r) Shaving machines (feed-in) (see figures 13a and 13b) It takes account of intended use, foreseeable misuse, compo
27、nent and systems failure. !This European Standard is not applicable to reciprocating roller machines which are manufactured before the date of its publication as EN.“ !This European Standard provides provisions for the reduction of noise emission at the design stage (see 5.2.4 and Annex A). However,
28、 it does not provide a noise test code for the determination by measurement of noise emission values for the machines it covers. Without such a code the manufacturer cannot fulfil his obligation to provide the noise emission values of the machines put on the market.“ !All the significant hazards (se
29、e Clause 4) are dealt with in this European Standard except the following:“ Dust, smoke and vapour emissions (see Annex B); Fire (see Annex C). For these hazards general guidelines are proposed in !normative annexes“. Designers and manufacturers shall verify directly that the methods adopted to redu
30、ce these hazards have been successful. 2 Normative references The following referenced documents are indispensable for the application of this document.

42、 danger zones are distinguished in order to better identify in this Standard the various hazards and relevant requirements. 3.2.1 working zone zone around a power driven working part in which the work process takes place for the treatment and processing or manufacturing of products. Part of the work
43、ing zone, in which operators introduce their hands whilst placing the skin prior to machine closure, defined as the “feeding zone“, has particular hazards and needs particular safety devices. NOTE In the text, where “feed rollers“ are mentioned, it is intended to also cover “feed conveyors“ unless o
44、therwise stated. 3.2.2 accessible zone any other danger zone 4 List of significant hazards !This clause contains all the significant hazards, hazardous situations and events, as far as they are dealt with in this European Standard, identified by risk assessment as significant for this type of machin
45、ery and which require action to eliminate or reduce the risk. The significant hazards for moving platen machines are outlined in 4.1 to 4.18. The danger zones which give rise to mechanical hazards are illustrated in Figures 1 to 13. The figures are informative only.“ The danger zones, operating cond
46、itions and situations that may lead to the hazards are detailed in clause 5.
