3 Terms, definitions and abbreviations
3.1 Terms and definitions
For the purposes of this European Standard, the terms and definitions given in EN 1070:1998 and the following
definitions apply. Further definitions are provided in relevant A and B standards and in annex A of EN 292-
2:1991/A1:1995.
3.1.1
ancillary device
device intended for use with the guillotine shear and integrated with it (e.g. devices for lubrication, feed, ejection)
3.1.2
beam
main reciprocating guillotine shear member holding the top blade. The top blade can be guided either by direct
slide (vertically up and down) or swinging beam
3.1.3
clamp
part of the machine which holds the sheet material in position on the work table during the cutting stroke. Also
called hold-down or jack
3.1.4
crocodile shears
shears having a shearing action like that of scissors. Power is applied in an angular direction around the pivot and
the action of the blades is guided only by the pivot
3.1.5
cycle (operating cycle)
movement completed by the moving parts from the cycle start position (normally the top dead centre) to the bottom
dead centre and back to the cycle stop position (normally the top dead centre). The operating cycle includes all
operations carried out during this movement

EN 13985:2003 (E)
3.1.6
dead centres
points at which the moving blade, during its travel, is
a) either at the end of the chosen closing stroke, known as the bottom dead centre (BDC),
b) or at the end of the chosen opening stroke, known as the top dead centre (TDC)
3.1.7
guillotine shears
machine, sometimes known simply as a guillotine or shears, consisting of side frames bridged by a work table to
which is fixed a bottom blade and a movable upper beam to which is fixed a top blade(s). The blades may also be
of fixed or variable angle (i.e. the angular relationship between the top and bottom blades)
Figure 1 — Guillotine shear
3.1.8
inching device; limited movement control device
control device, the actuation of which permits only a limited amount of travel of a machine element, thus minimising
risk as much as possible; further movement is precluded until there is subsequent and separate actuation of the
control (see 3.23.8 of EN 292-1:1991)
3.1.9
monitoring
safety function which ensures that a protective measure is initiated if the ability of a component or an element to
perform its function is diminished, or if the process conditions are changed in such a way that hazards are
generated (see 3.7.6 of EN 292-2:1991)
3.1.10
muting
temporary automatic suspension of a safety function(s) by safety related parts of the control system (see 3.7 of

time occurring from actuating the protective device to the cessation of hazardous motion, or to the machine
assuming a safe condition
3.1.12
redundancy
application of more than one device or system, or part of a device or a system, with the objective of ensuring that,
in the event of one failing to perform its function, another is available to perform that function (see 3.44 of

4 List of significant hazards
4.1 The list of hazards contained in Table 1 is the result of a hazard identification, their associated danger zones
and reference to protective measures for guillotine shears covered by the scope of this standard. The safety
requirements and/or protective measures and information for use contained in clauses 5 and 7 are based on a risk
assessment and deal with the identified hazards by either eliminating them or reducing the effects of the risks they
generate.
4.2 The risk assessment assumes foreseeable access from all directions, as well as unexpected and unintended
strokes or gravity falls. Risks to both the operators and other persons who can have access to the danger zones
are identified, taking into account hazards which can occur under various conditions of intended use (e.g.
commissioning, setting, production, maintenance, repair, decommissioning, dismantling - see also 3.11 of
EN 292-1:1991) during the life of the machine. The assessment includes an analysis of the effect of failure in the
control system.
4.3 The user of this standard (i.e. the designer, manufacturer, supplier) shall check that the list of significant
hazards in Table 1 is complete for the machine under consideration. If the user determines that there are additional
hazards then he shall analyse and evaluate the risks associated with these hazards in accordance with EN 1050
with particular attention to the intended use of the machine (e.g. commissioning, setting, production, maintenance,
repair, decommissioning, dismantling - see also 3.11 of EN 292-1:1991), and its reasonably foreseeable misuse.

5 Safety requirements and/or protective measures
5.1 General
The guillotine shears covered by this standard range in size from small to large machines with a single operator or
several operators.
The methods or measures to be implemented to eliminate the significant hazards or reduce their associated risks
are detailed in this clause in the following manner:
basic design considerations for major guillotine components or systems (see 5.2);
safeguarding against mechanical hazards in the blade area under different modes of production (see 5.3);
protection against hazards due to control system or control component failures (see 5.4);
safeguarding against hazards which can occur during setting, trial strokes, maintenance and lubrication (see
5.5);
safeguarding against other hazards (see 5.6 to 5.8).

EN 13985:2003 (E)
In addition, the machine shall be designed according to the principles of EN 292 for hazards relevant but not
significant which are not dealt with by this standard.
5.2 Basic design considerations
5.2.1 Brakes and friction clutches
5.2.1.1 Fluid or air pressure shall not be used to apply a brake unless means are provided to ensure that, in
the event of loss of fluid or air pressure, the integrity of the brake is maintained and the clutch is disengaged.
Diaphragms shall not be used to apply a brake.
5.2.1.2 The designer shall ensure that:
a) the springs used for applying the brake or disengaging the clutch are of compression type and well tried
components;
b) multiple assemblies are used;
c) all the springs are closely uniform in dimension, quality and rating;
d) the means of loading the springs are such that, when adjusted, the spring anchorages can be locked to
prevent slackening back;
e) the arrangements for spring housing and guiding, and of guide pins, are such as to minimize binding;
f) the brake can function even if 50 % of the spring assembly has failed.
5.2.1.3 The arrangement provided for engagement and disengagement of the clutch and brake shall not affect
their safe function.
NOTE Combined clutch and brake units are recommended so as to reduce the possibility of the overlapping of their
engagement.
5.2.1.4 The clutch and brake shall be designed so that failure of components e.g. for power transmission or
screws shall not prevent the clutch to be disengaged and the brake to be applied.
5.2.1.5 Any heat generated which can cause a hazardous situation shall be dissipated.
5.2.1.6 Effective arrangements shall
