Foreword
This document (prEN 1807-1:2009) has been prepared by Technical Committee CEN/TC 142 “Woodworking
machines - Safety”, the secretariat of which is held by UNI.
This document is currently submitted to the CEN Enquiry.
This document will supersede EN 1807:1999.
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 the Machinery Directive and Out
Door Noise Directive.
For relationship with EU Directives, see informative Annexes ZA and ZB, which are integral parts of this
document.
Organisations contributing to the preparation of this European Standard include European Committee of
Woodworking Machinery Manufacturers Association "EUMABOIS".
The European Standards produced by CEN/TC 142 are particular to woodworking machines and complement
the relevant A and B Standards on the subject of general safety (see introduction of EN ISO 12100-1:2003 for
a description of A, B and C standards).
Introduction
This document has been prepared to be a harmonized standard to provide one means of conforming to the
essential safety requirements of the Machinery Directive and associated EFTA regulations. This document is
a type "C“ standard as defined in EN ISO 12100-1:2003.
The machinery concerned and the extent to which hazards, hazardous situations and 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 type C standard take precedence over the provisions of other standards, for machines that
have been designed and built according to the provisions of this type C standard.
The requirements of this document are directed to manufacturers and their authorized representatives of table
band saws and band re-saws. They are also useful for designers.
This document also includes provisions and examples of information to be provided by the manufacturer to
the user.
1 Scope
This document deals with the significant hazards, hazardous situations and events as listed in Clause 4 which
are relevant to stationary and displaceable table band sawing machines and band re-saws with manual
loading and/or unloading, hereinafter referred to as “machines”, designed to cut solid wood, chipboard,
fibreboard, plywood, and also these materials if they are covered with plastic edging and/or plastic/light alloy
laminates, when they are used as intended and under the conditions foreseen by the manufacturer.
This European Standard does not apply to:
a) Transportable machines, i.e. machines set up on a bench or a table similar to a bench, which are
intended to carry out work in a stationary position, capable of being lifted by one person by hand. The
bench can also be an integrated part of the machine if it consists of hinged legs which can be extended
down;
NOTE 1 Transportable electrically driven machines are covered by the requirements of EN 61029-1:2000 together
with prEN 61029-2-5:2001
b) hand held motor-operated electric tools including any adaptation permitting their use in a different mode,
i.e. bench mounting.
NOTE 2 hand-held motor-operated electric tools are covered by the requirements of EN 60745-1:2006 together with
EN 60745-2-20:2003
c) log band saws
NOTE 3 log band saws are covered by prEN 1807-2:2008.
This document does not deal with the specific hazards related to thermal engine and P.T.O. equipment fitted
to the machine.
This document is not applicable to band sawing machines which are manufactured before the date of its
publication as EN.
NOTE 4 Machines covered by this document are listed under A.4 of Annex IV of the Machinery Directive.

and 4 also fulfil the requirement. Where category 2 is required categories 3 and 4 also fulfil the requirement,
where category 3 is required category 4 also fulfils the requirement.
NOTE 6.3 of EN 13849-1:2006 give useful information on combination of safety-related parts to the same or different
categories.
Verification: By checking the relevant drawings and/or circuit diagrams and inspection of the machine.
Components are considered well-tried if they comply with 6.2.4 of EN ISO 13849-1:2006 (see also Annex E).
NOTE 1 Well-tried electrical components are listed in Table D.3 of EN 13849-2:2003.
NOTE 2 EN 13849-2:2003 gives useful information on assessment of well-tried components, possible exclusion of
faults etc.
Verification: By checking the relevant drawings and/or circuit diagrams and inspection of the machine.
5.2.1.3 Use of electronic components
If electronic components are used the requirements given in Annex G shall be met.
Verification: By checking the relevant drawings and/or circuit diagrams, inspection of the machine,
measurement and relevant functional testing of the machine.
5.2.1.4 Use of protective devices
Protective devices shall be in accordance with the specific standards. For the devices listed below the
following requirements apply:
a) magnetic/proximity switches shall be in accordance with the requirements of 6.2 of EN 1088:1995 and
the related control system shall conform to category 3 in accordance with the requirements of
EN ISO 13849-1:2006;
b) a component failure shall not cause an unexpected movement (starting), a change of running
conditions during operation (adjustment of the speed or of a powered movement) and a failure of a
commanded stopping. Well known solutions such as monitoring, redundancy shall be used to achieve
category 3 in accordance with the requirements EN ISO 13849-1:2006;
c) if a time delay is used, it shall either be of fail safe technique or shall conform to the requirements of
category 1 or 3 according to EN ISO 13849-1:2006.
NOTE 1 Also see 5.4.9 for the EMC requirements on the complete band sawing machine.
Verification: By checking the relevant drawings and/or circuit diagrams, inspection of the machine,
measurement and relevant functional testing of the machine.
NOTE 2 For the components characteristics a confirmation from the components' manufacturers can be useful.
5.2.2 Position of controls
5.2.2.1 Table band saws
On table band saws electrical controls including the emergency stop control (if fitted) shall be positioned:
a) on the infeed side;
b) between 600 mm and 1400 mm from floor level;
and
c) either on a fixed part of the machine as shown in the shaded area in Figure 7 or on a moveable control
panel or a free-standing control console.
