Safety of machinery - Interlocking devices associated with guards - Principles for design and selection
This standard specifies principles for the design and selection - independent of the nature of the energy source - of interlocking devices associated with guards (as defined in 3.23.1 'interlocking device [interlock]', 3.22.4 'interlocking guard' and 3.22.5 'interlocking guard with guard locking' of EN 292-1). It also provides requirements specifically intended for electrical interlocking devices (see clause 6). This standard covers the parts of guards which actuate interlocking devices. Requirements for guards are given in prEN 953. The processing of the signal from the interlocking device to stop and immobilize the machine is dealt with in prEN 954-1.

5.7 Design to minimize defeat possibilities
5.7.1 General
Interlocking devices shall be designed and instructions for their installation and maintenance shall be given so
that they cannot be defeated in a simple manner.
NOTE "Defeat in a simple manner" means "intended operation achieved manually or with a readily available object".
Readily available objects may be :
screws, needles, sheet-metal pieces;
objects in daily use such as keys and coins;
spare actuators or spare keys for the trapped-key interlocking devices;
tools required by the intended use of the machine or readily available tools (e.g. screwdrivers, wrenches, hexagonal
keys and pliers.
“Defeat in a simple manner” includes the release of switches or actuators with the help of the above-mentioned tools, with
the intention to disable an interlocking device.

Introduction
The aim of this document is the specification of more precise requirements in order to improve the provisions
for minimizing the possibilities for defeat by machine operators. Research in some fields has shown that
operators often try to defeat a guard interlocking safety function by attempting to defeat the interlocking device,
the possibility of defeat being primarily attributable to shortcomings in the design of the machine.
1 Modification to 5.7
Delete 5.7 "Design to minimize defeat possibilities" and replace with the following:
“5.7 Design to minimize defeat possibilities
5.7.1 General
The requirements contained in this amendment for minimizing the possibilities for defeat of an interlocking
device need not apply if the safety interlocking function has other effective measures to minimize the
possibility of its defeat
