5 Safety requirements and/or measures
5.1 General
Machinery shall comply with the safety requirements and/or protective measures of this clause.
In addition, the machine shall be designed according to the principles of EN 12100 for hazards relevant but
not significant which are not dealt with by this European Standard (e.g. sharp edges of structural parts).
For hazards which are reduced by application of a B-Level standard such as EN 294, EN 418, EN 60204-1
etc., the manufacturer shall carry out a risk assessment to establish the requirements of the B-standard to be
applied. This specific risk assessment shall be part of the general risk assessment of the machine.
5.2 Common requirements for all cutting and punching machines
NOTE Some specific requirements in 5.3 are deviating from the following common requirements.
5.2.1 Mechanical Equipment
5.2.1.1 Safeguarding against the hazards generated by moving transmissions parts (such as pulleys,
belts, gears, rack, etc.), shall be ensured by:
 fixed enclosing guards in accordance with EN 953;
 movable interlocking guards without guard locking in accordance with EN 953, EN 1088, and Annex A of
this European Standard (the specific subclauses will indicate if A1, A2 or A3 of Annex A will apply).
5.2.1.2 Hazardous motion of moving machinery parts, feed systems, tools and workpieces shall be
safeguarded by the following, on the basis of risk assessment in accordance with EN 1050 and taking into
consideration the highest level of protection available:
 fixed enclosing guards or covers which satisfies EN 953;
 fixed distance guards which satisfy 3.2.2 of EN 953:1997 and the distances given in the appropriate Table
(1, 3 or 4) of EN 294:1992.
Where it is impossible to provide these protective measures, devices shall be provided which will affect a
shutdown of the hazardous motion before the danger zone is reached.
Devices which will affect this are:
 movable interlocking guards without guard locking which satisfy EN 953, EN 1088, and Annex A of this
European Standard;
NOTE For these machines, movable interlocking guards without guard locking are considered acceptable
because of the short stopping time of the moving parts.
 trip devices, such as:
 electrosensitive protective devices satisfying EN 61496-1, prEN 61496-2 and EN 999 or mec hanical
trip bars satisfying Annex C of this European Standard;
 two-hand control devices which satisfy EN 574 and EN 999.
Specific applications, if necessary, are given in the relevant subclause for each machine in 5.3.
5.2.1.3 On travelling head cutting presses or beam cutting presses with double tray feeder which may be
operated alternately by two persons, one at the front and the other at the rear, front and rear safeguarding
arrangements shall be identical; the design shall ensure that any motion can be actuated only by the operator
engaged in the working cycle, while the safeguarding arrangement on the side of the other operator is
operational.
5.2.2 Electrical equipment
5.2.2.1 Electrical systems and equipment shall be in accordance with EN 60204-1.
With respect to some clauses of EN 60204-1:1997, stated hereafter, the following shall apply:
 4.3:
A.C. supplies: in accordance with 4.3.2; D.C. supplies: in accordance with 4.3.3;
 6.2:
Protection in accordance with 6.2.2 or 6.2.3 and, where applicable 6.2.4;
 9.2.5.3/4:
Stop function and emergency stop function: stop category 0 or 1;
 9.4:
the safety related parts of the control system shall meet the requirements of this European Standard;
 12.3: degree of protection: at least IP 54.
5.2.2.2 All operating controls requiring routine adjustment for changing the working process shall be
located outside the electrical cabinet.
NOTE Controls for routine electrical adjustment are for example feed, speed, time, temperature or pressure variation.
5.2.3 Noise reduction
5.2.3.1 Noise reduction at source by design
Noise reduction shall be carried out by incorporating, as an integral part of the design, one or more of the
following features:
a) reduction of vibration through static and dynamic balancing of rotating parts;
b) reduction of vibration within the machine by reducing both the mass of the moving parts and their
acceleration;
c) reduction of impactive overclearance of rotational bearings by application of positive preloading;
d) proper choice and design of the energy-transfer components to eliminate bouncing;
e) proper choice and design of transmission components (gears, pulleys, belts, bearings and so on);
f) proper design of machine structures taking into account vibration damping and avoidance of structural
resonance.
This list of technical measures for noise reduction at source gives only examples and is not meant to be
complete. These measures are recommended but not compulsory. Other appropriate measures with identical
or greater efficacy can be selected taking into account EN ISO 11688-1.
NOTE EN ISO 11688-2 gives useful information on noise generation mechanisms in machinery.

5.2.3.2 Noise reduction by protective devices
If it is not possible to achieve the noise reduction at the source by design methods, then the following shall be
considered:
a) antivibration mountings should be fitted to reduce vibration transmission to the floor;
b) sound deadening of pneumatic discharges, vibration damping of hydraulic circuits.
Other devices with identical or greater efficacy may be used by the manufacturers.
5.2.3.3 Noise reduction by information
If consideration of noise reduction at the design stage shows that noise emission levels, after taking all
possible technical measures, will be so high that further protection of the operator will be necessary, the
information for use shall contain additional information (see 7.2).
5.2.4 High pressure fluid
To prevent high pressure ejection of fluid or ejection of a part of a burst component, hydraulic and pneumatic
systems shall satisfy 4.10 of EN ISO 12100-2:2003, EN 982 and EN 983.
5.2.5 Control systems
5.2.5.1 All machines shall have a start control and a stop control fitted at the working zone. The control
system shall automatically adopt a safe condition if any of the energy inputs are unavailable.
Hydraulic control equipment shall be in accordance with EN 982.
Pneumatic control equipment shall be in accordance with EN 983.
Electrical control equipment shall be in accordance with 5.2.2 and specific control requirements of individual
machines (see 5.3).

platform in accordance with EN ISO 14122-2 shall be provided; the platform shall be non-sloping and the
surface shall be made of non-slip material;
 possible need for integral lighting in accordance with EN 1837.
5.2.8 Danger signals
Danger and functional auditory and visual signals adopted shall satisfy the requirements listed in EN 981.
They shall be placed in order to satisfy the ergonomic requirements of Clause 4 of EN 981:1996.
