Tannery machines - Splitting and bandknife shearing machines - Safety requirements
This European Standard specifies safety requirements for design, construction, operation, adjustment, setting, cleaning and maintenance of splitting machines (see figures 1, 2) for limed hides and skins, wet blue and dry materials, bandknife shearing machines (see figures 3, 4, 5, 6) used in the splitting and shearing of leather and synthetic materials. This standard takes account of intended use, foreseeable misuse, component and systems failure. The machines are for fixed installation. This document is not applicable to the splitting and bandknife shearing machines which are manufactured before the date of its publication as EN." All the significant hazards listed in clause 4 are safeguarded by the requirements included in clause 5 except dust and fire. For these hazards general guidelines are proposed in normative annex A. Designers and manufacturers shall verify directly that the methods adopted to reduce these hazards have been successful.

Ta evropski standard opredeljuje varnostne zahteve za načrtovanje, gradnjo, obratovanje, prilagoditev, nastavitev, čiščenje in vzdrževanje strojev za cepljenje (glej Sliki 1, 2) za lužene kože, kože, strojene s kromovimi solmi, in suhe materiale, stroje za tračno striženje (glej Slike 3, 4, 5, 6), ki se uporabljajo za cepljenje in tračno striženje usnjenih in sintetičnih materialov. Ta standard upošteva predvideno uporabo, predvidljivo napačno uporabo ter okvaro komponent in sistemov. Stroji so namenjeni fiksni namestitvi. Ta dokument ne velja za stroje za cepljenje in tračno striženje, ki so proizvedeni pred datumom njegove objave kot EN. Zahteve, ki so vključene v Klavzuli 5, varujejo pred vsemi velikimi nevarnosti, ki so naštete v Klavzuli 4, razen prahu in ognja. Splošna navodila za te nevarnosti so predlagana v normativni Prilogi A. Načrtovalci in proizvajalci morajo neposredno potrditi, da so bile metode, uporabljene za zmanjšanje teh nevarnosti, uspešne.

EN 13112:2002+A1:2009 (E) 5 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 hazardous 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 been designed and built according to the provisions of this type C standard." 1 Scope This European Standard specifies safety requirements for design, construction, operation, adjustment, setting, cleaning and maintenance of splitting machines (see figures 1, 2) for limed hides and skins, wet blue and dry materials, bandknife shearing machines (see figures 3, 4, 5, 6) used in the splitting and shearing of leather and synthetic materials. This standard takes account of intended use, foreseeable misuse, component and systems failure. The machines are for fixed installation. !This document is not applicable to the splitting and bandknife shearing machines which are manufactured before the date of its publication as EN." All the significant hazards listed in clause 4 are safeguarded by the requirements included in clause 5 except dust and fire. For these hazards general guidelines are proposed in normative annex A. Designers and manufacturers shall verify directly that the methods adopted to reduce these hazards have been successful. This standard does not establish any requirements for electromagnetic disturbances. NOTE Directive 94/9/EC concerning equipment and protective systems intended for use in potentially explosive atmospheres can be applicable to the type of machine or equipment covered by this European Standard. The present standard does not necessarily comply with Directive 94/9/EC. Additional safety requirements in a future revision of this standard can be necessary to satisfy Directive 94/9/EC. 2 Normative references !The following referenced documents are indispensable for the application of this document.
