26、 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 t
27、ype 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
28、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 purp
29、oses 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
30、 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. Tooth form of the tooth roll: D
31、epth 800 mm. 5.2.1.1.4 The operation switch for the drive system of the tooth roll shall be a hold-to-run control. The tooth roll shall stop within 2 s, after the operator has released the operating switch (see 5.3.1). The operating switch can, for example, be foot, knee or belly operated and shall
32、be protected against unintentional actuation. 5.2.1.1.5 Normal positioning of machines The access to open derinding machines shall be prevented, except the operator side. This will be achieved e.g. by the following measures: normal positioning of a machine in a small working area An open derinding m
33、achine shall be positioned with one side towards a wall. The table and a container shall be placed on the other free sides to receive the round products (see Figures 10 and paragraph 7.1a). The operator stands in front of the open derinding machine. By this way of positioning access to the open deri
34、nding machine is prevented for other persons. normal machine positioning in working area with cutting line An open derinding machine shall be positioned with one side against the cutting line. The table and a container will be placed on the other free sides in order to receive the round products (se
35、e Figure 11 and paragraph 7.1a). The operator stands in front of the open derinding machine. By this way of positioning access to the open derinding machine is prevented for other persons.

Flat products (e.g. fatbacks) shall only be used in conjunction with automatic derinding machines (see 5.2.2). 5.2
39、.1.1.8 Wearing of protective gloves When operating an open derinding machine, the operator shall only wear manufacturer approved protective gloves. Metal wire mesh gloves, or metal wire reinforced gloves shall not be worn (see 7.1.d). On open derinding machines a permanently fixed notification shall
40、 be present, with the following text: “Attention: Do not wear metal wire mesh gloves or metal wire reinforced gloves”. 5.2.1.1.9 Operator training The manufacturer shall devise safe working procedures to be followed by operators. These shall be included in the instructions for use (see 5.2.1.1.10),
41、together with the elements of training and frequency of retraining to be given to the operators.5.2.1.1.10 Information in the instruction handbook. 5.2.1.1.10 The manufacturer shall in the instruction handbook describe clearly: processing of tall, round products ( 5.2.1.1.3); the normal positioning
42、of machines in small working areas ( 5.2.1.1.5, paragraph 1); the normal machine positioning in working areas with cutting line (5.2.1.1.5, paragraph 2); further possibility of machine positioning (5.2.1.1.6); normal operating conditions on open derinding machines (5.2.1.1.7); wearing of protective
43、gloves (5.2.1.1.8); BS EN 12355:2003+A1:2010EN 12355:2003+A1:2010 (E) 20 operator training before starting the process (5.2.1.1.9). 5.2.1.2 - Zone 2 The access to the inrunning nip between tooth roll and stripper comb shall be prevented. This can be achieved e.g. by observance of the following measu
44、res: 5.2.1.2.1 The angle between tooth roll and stripper comb shall be 90 (see Figure 13). 5.2.1.2.2 The stripper comb shall be interlocked.

This can be achieved e.g. by the following measures: 5.2.1.3.1 The
46、 distance between a rotating tooth roll and a fixed machine part shall be 80 mm (see Figure 13). 5.2.1.3.2 Shorter distances shall be guarded by a protective bar. The angle shall be 90 and the distance between protective bar and tooth roll shall be 2 mm (see Figure 15). BS EN 12355:2003+A1:2010EN 12
