Foreword
This document (EN 12268:2003) has been prepared by Technical Committee CEN/TC 153 “Food processing
machinery – Safety and hygiene requirements”, the secretariat of which is held by DIN.
It has been prepared by Working Group 2 "Meat Processing Machinery" of CEN/TC 153.
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by endorsement, at the latest by October 2003, and conflicting national standards shall be withdrawn at the latest
by October 2003.
This document has been prepared under a mandate given to CEN by the European Commission and the European
Free Trade Association, and supports essential requirements of EC Directives.
For relationship with EC Directives, see informative annex ZA, which is an integral part of this document.
It is one of a series of standards which have been prepared for machines and equipment for meat processing in
compliance with EN 1672-2:1997and annex C and attends to machines, which are attached by Annex IV of
Machinery Directive 89/37 EEC. Band saw machines, which are not fed by hand, do not come under Annex IV.
Annexes A, B and C are normative.
This European Standard also contains a Bibliography.
According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following
countries are bound to implement this European Standard: Austria, Belgium, Czech Republic, Denmark, Finland,
France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Luxembourg, Malta, Netherlands, Norway, Portugal,
Slovakia, Spain, Sweden, Switzerland and the United Kingdom.
Introduction
This European Standard covers
Band saw machines designed as table-top machines with and without base
Band saw machines designed as floor-type machines
Band saw machines integrated in a cutting line
The extent to which hazards are covered is indicated in this European Standard. For other hazards which are not
covered by this European Standard, machinery should comply with EN 292 where applicable.
1 Scope
This European Standard specifies requirements for the design and manufacturing of band saw machines (see
Figures 1 to 5).
The machines covered by this European Standard are used to cut bone and meat.
The band saw machines covered by this European Standard do not include band saw machines for processing
wood and similar materials and the requirements of EN 1807 do not apply.
Band saw machines for domestic use are not included in this European Standard.
This European Standard only applies to machines which are manufactured after the date of issue of this European
Standard.
This European Standard covers the following types of machines:
Band saw machines which are placed on the floor and can be wheel-mounted (see Figure 6).
Type A
Band saw machine with a feed table and a fixed product pusher
Cutting height SH < 250 mm
Location: Table (see Figure 1) or base (see Figure 2). Distance A from the floor to the top surface of the feed table
is between 800 mm and 1050 mm.

Type B
Band saw machine with a feed table, a protective rail and a cutting height 250 mm < SH < 420 mm.
Distance A from the floor to the top surface of the feed table is between 800 mm and 1050 mm. Location: floor (see
Figure 3)
Type C
Band saw machine with a sliding feed table, a protective rail and a cutting height 250 mm < SH < 420 mm.
Distance A from the floor to the top surface of the sliding feed table is between 800 mm and 1050 mm.
Location: floor (see Figure 4).

Type D
Band saw machine with feed and removal unit (e.g. roller conveyor, conveyor belt); integrated in a cutting plant,
cutting height SH < 550mm.
Distance A from the floor to the feed surface is between 800 mm and 1050 mm. Location: floor (see Figure 5).
SH < 550 mm
Key
1 Roller conveyor or transport conveyor
Figure 5 — Type D, Band saw machine with feed and removal unit
Band saw machines consist of a machine casing, a fixed feed table or a sliding feed table, a roller conveyor or
conveyor belt, a product pusher, a height-adjustable protective rail, a top and a bottom wheel, a saw blade, an
upper and lower blade guide, a blade tensioning device, a drive and electrical components, depending on machine
type. The requirements for automatic loading/unloading systems, conveyors, etc. do not fall within the scope of this
European Standard.
The intended uses of the machines are described in clause 7.
On floor-type band saw machines, the product to be cut is placed by hand onto the fixed feed table or sliding feed
table and pushed against the cutting zone of the saw blade by means of the product pusher or the rear table wall
on the sliding feed table or by means of the roller conveyor or conveyor belt and sawed.
