EN 12355:2022

This document 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 document deals with the hazards which can arise during commissioning, operation, cleaning, use, maintenance and decommissioning of the machine.
The machines described in this standard are used for derinding-, skinning- and membrane removal of meat and fish by cutting at a straight blade and/or cutting with circular blades. Feeding could be done manually or automatically.
Using open derinding-, skinning- and membrane removal machines, the product is guided by hand towards the cutting device.
With automatic derinding-, skinning and membrane removal machines the product is transported by an infeed conveyor against the cutting device. Product with a weight > 25 kg has to be processed by an automatic machine.
Derinding-, skinning-, and membrane removal machines for domestic purposes, hand-guided machines and table-top machines are not covered by this standard.
This document only applies to machines which are manufactured after the date of issue of this document.
This document covers the following types of machines:
a)   open derinding machines (see Figure 1 and Figure 2) with infeed table and a distance h between the standing position and the surface of the infeed table from 800 mm to 1 050 mm. The cutting thickness shall be t ≤ 5 mm;
b)   open skinning- and membrane removal machines (see Figure 1 and Figure 3) with infeed table and a distance h between the standing position and the surface of the infeed table from 800 mm to 1 050 mm. The cutting thickness shall be t ≤ 0,5 mm.
