Safety of machinery - Pressure-sensitive protective devices - Part 1: General principles for design and testing of pressure-sensitive mats and pressure-sensitive floors (ISO 13856-1:2013)

This part of ISO 13856 establishes general principles and specifies requirements for the design and testing of pressure-sensitive mats and pressure-sensitive floors normally actuated by the feet for use as devices for protecting persons from hazardous machinery. The minimum safety requirements for the performance, marking and documentation are given. This part of ISO 13856 is applicable to pressure-sensitive mats and pressure-sensitive floors, regardless of the type of energy used (e.g. electrical, hydraulic, pneumatic or mechanical), designed to detect - persons weighing more than 35 kg, and - persons (e.g. children) weighing more than 20 kg. It is not applicable to the detection of persons weighing less than 20 kg. It does not specify the following because they are application-specific: a) dimensions or configuration of the effective sensing area of pressure-sensitive mat(s) or pressuresensitive floor(s) in relation to any particular application; b) when pressure-sensitive mats or floors are appropriate in a particular situation; c) performance levels (PLs) for safety-related parts of control systems (SRP/CSs) other than providing a minimum level. This part of ISO 13856 gives guidance to assist the user (i.e. machinery manufacturer and/or user of the machinery) in providing an adequate arrangement.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International
Standards adopted by the technical committees are circulated to the member bodies for voting.
Publication as an International Standard requires approval by at least 75 % of the member bodies
casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 13856-1 was prepared by Technical Committee ISO/TC 199, Safety of machinery and by Technical
Committee CEN/TC 114, Safety of machinery in collaboration.
This second edition cancels and replaces the first edition (ISO 13856-1:2001) which has been
technically revised.
ISO 13856 consists of the following parts, under the general title Safety of machinery — Pressure-sensitive
protective devices:
— Part 1: General principles for design and testing of pressure-sensitive mats and pressure-sensitive floors
— Part 2: General principles for design and testing of pressure-sensitive edges and pressure-sensitive bars
— Part 3: General principles for design and testing of pressure-sensitive bumpers, plates, wires and
similar devices

ISO 13856-1:2013(E)

Introduction
The structure of safety standards in the field of machinery is as follows:
a) Type-A standards (basic safety standards) giving basic concepts, principles for design, and general
aspects that can be applied to all machinery;
b) Type-B standards (generic safety standards) dealing with one safety aspect or one type of safeguard
that can be used across a wide range of machinery:
— Type-B1 standards on particular safety aspects (e.g. safety distances, surface temperature, noise);
— Type-B2 standards on safeguards (e.g. two-hand controls, interlocking devices, pressure-
sensitive devices, guards);
c) Type-C standards (machine safety standards) dealing with detailed safety requirements for a
particular machine or group of machines.
This document is a type-B2 standard as stated in ISO 12100.
The requirements of this document can be supplemented or modified by a type-C standard.
For machines which are covered by the scope of a type-C standard and which have been designed and built
according to the requirements of that standard, the requirements of that type-C standard take precedence.
The safeguarding of machinery (see ISO 12100:2010, 3.21) can be achieved by many different means.
These means include guards which prevent access to the hazard zone by means of a physical barrier
(for example, interlocking guards according to ISO 14119 or fixed guards according to ISO 14120) and
protective devices (for example, electro-sensitive protective equipment according to IEC 61496-1 or
pressure-sensitive protective devices according to this part of ISO 13856).
Type-C standards makers and designers of machinery/installations consider the best way to achieve
the required level of safety taking into account the intended application and the results of the risk
assessment (see ISO 12100).
The required solution can also be to combine several of these different means: the machinery/installation
supplier and the user examine together carefully the existing hazards and constraints before making
their decision on the choice of safeguarding.
Pressure-sensitive protective devices are used in a wide range of applications with different conditions
of use relating, for example, to extremes of loading or electrical, physical and chemical environments.
They are interfaced with machine controls to ensure that the machine reverts to a safe condition if the
sensitive protective equipment is actuated.
ISO 13856 is restricted to the design of pressure-sensitive protective devices so that they can be used
when the risk assessment carried out by the machine manufacturer and/or relevant type-C standard,
when available, shows this to be appropriate.

Safety of machinery — Pressure-sensitive protective
devices —
Part 1:
General principles for design and testing of pressure-
sensitive mats and pressure-sensitive floors
1 Scope
This part of ISO 13856 establishes general principles and specifies requirements for the design and
testing of pressure-sensitive mats and pressure-sensitive floors normally actuated by the feet for use as
devices for protecting persons from hazardous machinery. The minimum safety requirements for the
performance, marking and documentation are given.
This part of ISO 13856 is applicable to pressure-sensitive mats and pressure-sensitive floors, regardless
of the type of energy used (e.g. electrical, hydraulic, pneumatic or mechanical), designed to detect
— persons weighing more than 35 kg, and
— persons (e.g. children) weighing more than 20 kg.
It is not applicable to the detection of persons weighing less than 20 kg.
It does not specify the following because they are application-specific:
a) dimensions or configuration of the effective sensing area of pressure-sensitive mat(s) or pressure-
sensitive floor(s) in relation to any particular application;
b) when pressure-sensitive mats or floors are appropriate in a particular situation;
c) performance levels (PLs) for safety-related parts of control systems (SRP/CSs) other than providing
a minimum level.
This part of ISO 13856 gives guidance to assist the user (i.e. machinery manufacturer and/or user of the
machinery) in providing an adequate arrangement.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies
(ISO member bodies). The work of preparing International Standards is normally carried out through ISO
technical committees. Each member body interested in a subject for which a technical committee has been
established has the right to be represented on that committee. International organizations, governmental and
non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the
International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 13856-1 was prepared by Technical Committee ISO/TC 199, Safety of machinery and by Technical
Committee CEN/TC 114, Safety of machinery in collaboration.
ISO 13856 consists of the following parts, under the general title Safety of machinery — Pressure-sensitive
protective devices:
⎯ Part 1: General principles for the design and testing of pressure-sensitive mats and pressure-sensitive
floors
⎯ Part 2: General principles for the design and testing of pressure-sensitive edges and pressure-sensitive
bars
⎯ Part 3: General principles for the design and testing of pressure-sensitive bumpers and similar devices

Introduction
The structure of safety standards in the field of machinery is as follows:
a) Type-A standards (basic safety standards) giving basic concepts, principles for design, and general
aspects that can be applied to all machinery;
b) Type-B standards (generic safety standards) dealing with one safety aspect or one type of safeguard that
can be used across a wide range of machinery:
⎯ Type-B1 standards on particular safety aspects (e.g. safety distances, surface temperature, noise);
⎯ Type-B2 standards on safeguards (e.g. two-hand controls, interlocking devices, pressure-sensitive
devices, guards);
c) Type-C standards (machine safety standards) dealing with detailed safety requirements for a particular
machine or group of machines.
This document is a type-B standard as stated in ISO 12100.
The requirements of this document can be supplemented or modified by a type-C standard.
For machines which are covered by the scope of a type-C standard and which have been designed and built
according to the requirements of that standard, the requirements of that type-C standard take precedence.
ISO/TC 199 has a mandate in this area to produce type-A and type-B standards, which will allow verification
of conformity with the essential health and safety requirements (EHSRs) relating to the design and
construction of machinery.
The safeguarding of machinery (see ISO 12100:2010, 3.21) can be achieved by many different means. These
means include guards which prevent access to the hazard zone by means of a physical barrier (for example,
interlocking guards according to ISO 14119 and fixed guards according to ISO 14120) and protective devices
(for example, electro-sensitive protective equipment according to IEC 61496-1 and pressure-sensitive
protective devices according to this part of ISO 13856).
Type-C standards makers and designers of machinery / installations should consider the best way to achieve
the required level of safety taking into account the intended application and the results of the risk assessment
(see ISO 12100).
The best solution can also be to combine several of these different means. The machinery/installation supplier
and the user should examine together carefully the existing constraints before making their decision on the
choice of safeguarding.
Pressure-sensitive protective devices are used in a wide range of applications with different conditions of use
relating, for example, to extremes of loading or electrical, physical and chemical environments. They are
interfaced with machine controls to ensure that the machine reverts to a safe condition if the sensitive
protective equipment is actuated.
Each type of application presents particular hazards. It is not the intention of this part of ISO 13856 to identify
those hazards nor to recommend specific methods of application to particular machines. This is normally the
aim of type-C standards.

DRAFT INTERNATIONAL STANDARD ISO/DIS 13856-1

Safety of machinery — Pressure-sensitive protective devices —
Part 1:
General principles for design and testing of pressure-sensitive
mats and pressure-sensitive floors
1 Scope
This part of ISO 13856 specifies requirements for pressure-sensitive mats and pressure-sensitive floors
normally actuated by the feet for use as protective devices to protect persons from hazardous machinery. The
minimum safety requirements for the performance, marking and documentation are given.
This part of ISO 13856 is applicable to pressure-sensitive mats and pressure-sensitive floors, regardless of
type of energy used (e.g. electrical, hydraulic, pneumatic or mechanical) which are designed to detect:
a) persons weighing more than 35 kg; and
b) persons (e.g. children) weighing more than 20 kg.
This part of ISO 13856 is not applicable for the detection of persons weighing less than 20 kg.
This part of ISO 13856 does not specify the dimensions or the configuration of the effective sensing area of
pressure-sensitive mat(s) or pressure-sensitive floor(s) in relation to any particular application. However, there
is a requirement for the manufacturer of the protective 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.
