DIN EN 972:2011-07 EN 972:1998+A1:2010 (E) 4 Introduction !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 haz
26、ardous events are covered are indicated in the scope of this document. 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
27、 been designed and built according to the provisions of this type C standard.“ 1 Scope This European Standard specifies safety requirements for 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 ani
28、mal hides and skins. They have a reciprocating opening and closing motion of the feed rollers or conveyors which, if required, may also reverse their direction. This standard covers the following reciprocating roller machines (see figures 1 to 13 for typical configurations and annex D for descriptio
29、ns): a) Buffing machines (see figures 1a and 1b) b) Polishing machines (see figures 1a and 1b) c) Ironing machines (woolskins and fur) (see figures 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 ma
30、chines (see figures 5a and 5b) g) Setting-out machines (see figures 6a and 6b) h) Dewooling machines (see figures 6a and 6b) i) Scudding machines (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 machine
31、s (see figures 7a and 7b) m) Cylinder staking machines (see figures 8a and 8b) n) Fleshing machines (see figures 9a and 9b) o) Demanuring machines (see figures 10a and 10b) DIN EN 972:2011-07 EN 972:1998+A1:2010 (E) 5 p) Wet wheeling machines (see figures 11a and 11b) q) Shaving machines (feed-out)
32、(see figures 12a and 12b) r) Shaving machines (feed-in) (see figures 13a and 13b) It takes account of intended use, foreseeable misuse, component and systems failure. !This European Standard is not applicable to reciprocating roller machines which are manufactured before the date of its publication
33、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, 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 manufa
34、cturer cannot fulfil his obligation to provide the noise emission values of the machines put on the market.“ !All the significant hazards (see 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 hazar
35、ds general guidelines are proposed in !normative annexes“. Designers and manufacturers shall verify directly that the methods adopted to reduce these hazards have been successful. 2 Normative references The following referenced documents are indispensable for the application of this document.
