EN 12355:2003+A1:2010 (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 1.1 This European Standard applies to design, manufacturing, installation, transportation, electrical equipment and cleaning of derinding-, skinning-, and membrane removal machines (see Figures 1 to 5). The machines described in this standard are used for derinding-, skinning- and membrane removal of meat and fish by cutting at a blade device. Derinding-, skinning-, and membrane removal machines for domestic purposes and table-top machines are not covered by this standard. !This European Standard relates to: derinding machines with tooth roll, hold down roller and blade device; skinning- and membrane removal machines with transport- and stripper roll as well as a blade device." This standard only applies to machines which are manufactured after the date of issue of this standard. 1.2 This standard covers the following types of machines: Open derinding machines with infeed table and a distance between the floor and the surface of the infeed table from 800 mm to 1 050 mm.

Derinding-, skinning- and membrane removal machines can e.g. be equipped with a: infeed and outfeed table; infeed- and outfeed conveyor belts; blade device; double blade; hold down device, (e.g. hold down rollers, belts or fingers); circular knives inside or instead of hold down rollers; stripper comb/stripper roll/stripper rake. Derinding-, skinning- and membrane removal machines can be mobile (see Figures 1 and 3). 1.3 Intended use !This European Standard deals with all significant hazards, hazardous situations and events relevant to derinding-, skinning- and membrane removal machines, when they are used as intended and under conditions of misuse which are reasonably foreseeable by the manufacturer (see Clause 4). This European Standard deals with the hazards which can arise during commissioning, operation, cleaning, use, maintenance and decommissioning of the machine." SIST EN 12355:2003+A1:2010
EN 12355:2003+A1:2010 (E) 9 The product (raw meat or raw fish) with a weight < 15 kg which is to be processed is either fed by hand or by an infeed device (e.g. infeed conveyor belt) and a hold down device carried to the tooth or transport roller. Using open derinding-, skinning- and membrane removal machines, the product is pressed by hand against the blade device and the rind, the skin or the membrane is cut off by the blade. 1.4 Not intended use A not intended use is e.g.: the wrong installation of a derinding-, skinning- and membrane removal machine; the processing of flat products on open derinding machines; working on open derinding-, skinning- and membrane removal machines without using the gloves which the manufacturer recommends; manipulation of interlocking systems on safety devices; using of cleaning- and disinfection detergents, which are not recommended by the manufacturer in the instructions for use. 2 Normative references !The following referenced documents are indispensable for the application of this document.
