Foreword
This document (EN 1760-3:2004) has been prepared by Technical Committee CEN/TC 114 “Safety of
machinery”, the secretariat of which is held by DIN.
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text or by endorsement, at the latest by February 2005, and conflicting national standards shall be withdrawn
at the latest by February 2005.
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 EU Directive(s).
For relationship with EU Directive(s), see informative Annex ZA, which is an integral part of this document.
This is the third part of a multi-part standard dealing with pressure sensitive protective devices which will cover
safety devices that detect the presence of a person through the application of a pressure or force by a part of
the persons body. After actuation they give a stop command which is used by the control system of a machine
to provide protection for the person who caused the device to be actuated.
The other parts are:
EN 1760-1, Safety of machinery - Pressure sensitive protective devices - Part 1: General principles for the
design and testing of pressure sensitive mats and pressure sensitive floors.
EN 1760-2, Safety of machinery - Pressure sensitive protective devices - Part 2: General principles for design
and testing of pressure sensitive edges and pressure sensitive bars.
The safeguarding of machinery (see EN ISO 12100-1: 2003, 3.20) can be achieved by many different means.
These means include guards which prevent access to the hazard zone by means of a physical barrier (e.g.
fixed guards to EN 953 and interlocking guards to EN 1088); and protective devices, (e.g. electro-sensitive
protective equipment to EN 61496 and pressure-sensitive protective devices to this European Standard).
Designers of machinery (including e.g. vehicles) should consider the way to achieve the required level of
safety taking into account the intended application and the results of the risk assessment (see EN 1050). The
best solution may combine several of these different means. It is recommended that the machinery / vehicle
supplier and the user examine together carefully the existing constraints before making their decision on the
choice of safeguarding means.
This European Standard does not specify the dimensions and the configuration of the effective sensing
surface of pressure sensitive protective devices in relation to any particular application. However, there is a
requirement for the manufacturer of any safety device to provide sufficient information to enable the user (i.e.
the machinery manufacturer and / or the user of the machinery) to specify an adequate arrangement.
According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following
countries are bound to implement this European Standard: Austria, Belgium, Cyprus, Czech Republic,
Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania,
Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Slovakia, Slovenia, Spain, Sweden, Switzerland
and United Kingdom.
Introduction
Pressure sensitive protective devices are used in a wide range of applications with different conditions of use
relating, for example, to the maximum and minimum values of loading, electrical, physical and chemical
environments. They are interfaced with machinery controls to ensure that the machine reverts to a safe
condition when the device is actuated.
The forces given in this document should not be considered as those which will always avoid injury or fatal
accidents. This depends upon several criteria which include the sensor, the actuating speed, the contact area,
the material used and the part of the body affected.
The forces given in this document are primarily intended for the purpose of assessing the performance of the
pressure-sensitive protective devices. These forces are under further investigation.
Each type of application of pressure sensitive protective devices can present particular hazards. It is not the
intention of this document to identify those hazards nor to recommend specific applications to particular
equipment. Particular applications may also necessitate special requirements which are not included in this
document.
This document is a type B standard as stated in EN 1070.
The provisions of this document may be supplemented or modified by a type C standard.
