5、d is 1 February 2011. National foreword This standard includes safety requirements. This standard has been prepared by Technical Committee CEN/TC 153 “Machinery intended for use with foodstuffs and feed” (Secretariat: DIN, Germany). The responsible German body involved in its preparation was the Nor
6、menausschuss Maschinenbau (Mechanical Engineering Standards Committee), Working Committee NA 060-18-02 AA Fleischverarbeitungs-maschinen of Section Nahrungsmittelmaschinen. Stakeholders were involved in the development of the standard. This standard contains specifications meeting the essential requ
7、irements set out in Annex I of the new “Machinery Directive”, Directive 2006/42/EC, and which apply to machines that are either first placed on the market or commissioned within the EEA. This standard serves to facilitate proof of compliance with the essential requirements of that directive. Once th
8、is standard is cited in the Official Journal of the European Union, it is deemed a “harmonized” standard and thus, a manufacturer applying this standard may assume compliance with the requirements of the Machinery Directive (“presumption of conformity”). The European Standards referred to in Clause
9、2 and in the Bibliography of the EN have been published as the corresponding DIN EN or DIN EN ISO Standards with the same number. Amendments This standard differs from DIN EN 12355:2003-06 as follows: a) the standard has been brought in line with the new Machinery Directive 2006/42/EC; b) Annex ZA (
10、informative) “Relationship between this European Standard and the Essential Requirements of EU Directive 2006/42/EC” has been added.

The machinery concerned and the extent to which hazards, hazardous situations and hazardous events are covered are indicated in t
31、he 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 pr
32、ovisions 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 d
33、erinding-, 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 do
34、wn 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 der
35、inding 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: Depth 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
36、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 be protected against unintentional actuation. 5.2.1.1.5 Normal positioning of machines The access to open derinding machines shall be prevent
37、ed, 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 machine 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 rou
38、nd 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 derinding machine is prevented for other persons. normal machine positioning in working area with cutting line An open derinding machine shall be
39、 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 (see 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 de
40、rinding machine is prevented for other persons.

The dimensions of the guardings shall be in
42、accordance with EN 294.

43、n derinding machines (see 5.2.1.1.10). Flat products (e.g. fatbacks) shall only be used in conjunction with automatic derinding machines (see 5.2.2). 5.2.1.1.8 Wearing of protective gloves When operating an open derinding machine, the operator shall only wear manufacturer approved protective gloves.
44、 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 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
45、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), 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.
46、 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 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, paragra
47、ph 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 gloves (5.2.1.1.8); DIN EN 12355:2011-02 EN 12355:2003+A1:2010 (E) 20 operator training before starting the process (5.2.1.1.9). 5.2.1.2 - Zone 2 T
48、he 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 measures: 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.
