Foreword
This European Standard (EN 12984:2005) has been prepared by Technical Committee CEN/TC “Food
processing machinery — Safety and hygiene requirements”, the secretariat of which is held by DIN.
This European Standard shall be given the status of a national standard, either by publication of an identical
text or by endorsement, at the latest by May 2006, and conflicting national standards shall be withdrawn at the
latest by May 2006.
This European Standard has been prepared under a mandate given to CEN by the European Commission
and the European Free Trade Association, and supports essential requirements of EU Directive(s).
For relationship with EU Directive(s), see informative Annex ZA, which is an integral part of this European
Standard.
It is one of a series of European Standards for meat processing machinery, in compliance with EN 1672-2 and
Annex B.
According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following
countries are bound to implement this European Standard: Austria, Belgium, Cyprus, Czech Republic,
Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania,
Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Slovakia, Slovenia, Spain, Sweden, Switzerland
and United Kingdom.
Introduction
This European Standard is a type C standard as stated in EN ISO 12100-1.
The machinery concerned and the extent to which hazards, hazardous situations and events are covered are
indicated in the scope of this European Standard.
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 covers portable and/or hand-guided machines and appliances equipped with
mechanically driven cutting tools.
This European Standard specifies requirements for the design and manufacture of portable and/or hand-
guided machines and appliances equipped with electrically, hydraulically or pneumatically driven cutting tools
(see Figures 1 to 9), hereinafter referred to as “machines”.
The machines covered by this European Standard are used for slaughtering animals, for cutting up animal
carcasses, poultry and other foodstuff such as e.g. fish.
They are mainly intended for use in slaughterhouses and rooms, which are used for cutting and preparing.
These machines are used for the industry and trade.
This European Standard deals with all significant hazards, hazardous situations and events relevant to
machines, appliances and machinery, when they are used as intended and under the conditions foreseen by
the manufacturer (see Clause 4).
This European Standard deals with the hazards which can arise during commissioning, operation,
maintenance and de-commissioning of the machine.
This European Standard is not applicable to portable and/or hand-guided machines and appliances equipped
with electrically, hydraulically or pneumatically driven cutting tools, which are manufactured before the date of
publication of this European Standard by CEN.
1.2 This European Standard covers the following machines subdivided into tool types:
1.2.1 Saws (see Figures 1 to 5)
 Circular saws (see Figures 1 and 2);
 straight blade reciprocating saws (see Figures 3 and 4);
 band saws (see Figure 5).

1.2.3 Knives (see Figures 8 and 9)
 Ring-blade circular knives;
 circular knives with simple or double blade;
 reciprocating knives with one or two straight blades;
 rotating knives.
Figure 8 — Derinder Figure 9 — Flexible driven circular knife

Portable and/or hand-guided machines are constructed of a machine housing with a motor or pressure
cylinder within the housing, or a motor which drives the tool via a flexible drive cable, the tool being hand-held
at the place of use or being hand-guided on a movable device.
The motor or drive can comprise electrical, hydraulic or pneumatic components.
For weight balancing, a suspension unit with a tensioning spring or a counter-balancer can make the work
easier for the operator. This equipment is not covered by this European Standard.
1.3 Intended use
Portable and/or hand-guided machines are used on suspended or lying, stunned and blood-drained animals
for cutting off legs, feet and horns, for cutting out anuses, for skinning, for opening the sternum, for halving,
quartering or further cutting carcasses and for removing fat.
Although it should be advised against, this European Standard, taking into account practice, deals with the
hazards due to cleaning with pressurised water.
With the aim of clarifying the intentions of this European Standard and avoiding doubts when reading it, the
following assumptions were made for operation:
 only designated and instructed persons operate the machine,
 place of use is adequately lit, and
the equipment will be used in an environment with hygiene hazards but without other special hazards.
