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.

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-B1 standard as stated in ISO 12100.
This document is of relevance, in particular, for the following stakeholder groups representing the
market players with regard to machinery safety:
— machine manufacturers (small, medium and large enterprises);
— health and safety bodies (regulators, accident prevention organisations, market surveillance etc.);
Others can be affected by the level of machinery safety achieved with the means of the document by the
above-mentioned stakeholder groups:
— machine users/employers (small, medium and large enterprises);
— machine users/employees (e.g. trade unions, organizations for people with special needs);
— service providers, e. g. for maintenance (small, medium and large enterprises);
— consumers (in case of machinery intended for use by consumers).
The above-mentioned stakeholder groups have been given the possibility to participate at the drafting
process of this document.
In addition, this document is intended for standardization bodies elaborating type-C standards.
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 type-C standard, the following applies: if the requirements
of that type-C standard deviate from the requirements in type-B standards, the requirements of that
type-C standard take precedence over the provisions of other standards.
Correct positioning of safety devices are critical for them to be effective. In deciding on these positions,
a number of aspects are taken into account, such as:
— the necessity of a risk assessment according to ISO 12100;
— the practical experience in the use of the machine;
— the overall system response time;
— the time taken to achieve the intended risk reduction following operation of the safeguard, for
example to stop the machine;

— the bio-mechanical and anthropometric data;
— any intrusion by a part of the body towards the hazard zone until the protective device is actuated;
— the path taken by the body part when moving from the detection zone towards the hazard zone;
— the possible presence of a person between the safeguard and the hazard zone;
— the possibility of undetected access to the hazard zone.

DRAFT INTERNATIONAL STANDARD ISO/DIS 13855:2022(E)
Safety of machinery — Positioning of safeguards with
respect to the approach of the human body
1 Scope
This document specifies requirements for the positioning of safeguards with respect to the approach of
the human body or its parts from the detection zone, plane, line, point or interlocking guard to:
— the nearest hazard within the span-of-control of the safeguard, and
— any safety-related manual control device.
Approaches such as running, jumping or falling, are not considered in this document.
NOTE 1 The values for approach speeds (walking speed and upper limb movement) in this document are time
tested and proven in practical experience.
NOTE 2 Other types of approach can result in approach speeds that are higher or lower than those defined in
this document.
This document applies for safeguards used on machinery for the protection of persons 14 years and
older.
Safeguards considered in this document include:
a) electro-sensitive protective equipment (ESPE) such as:
— active opto-electronic protective devices (AOPDs) as described in IEC 61496-2;
— active opto-electronic protective devices responsive to diffuse reflection that have one or more
detection zone(s) specified in two dimensions (AOPDDRs-2D) as described in IEC 61496-3;
— active opto-electronic protective devices responsive to diffuse reflection that has one or more
detection zone(s) specified in three dimensions (AOPDDRs-3D) as described in IEC 61496-3;
— vision based protective devices (VBPDPP) as described in IEC/TS 61496-4-2
— vision based protective devices (VBPDST) as described in IEC/TS 61496-4-3
b) pressure-sensitive mats and floors as described in ISO 13856-1;
c) two-hand control devices as described in ISO 13851;
d) single control device;
e) interlocking guards as described in ISO 14119;
f) pressure-sensitive edges as described in ISO 13856-2 and bumpers as described in ISO 13856-3.
This document is not applicable to safeguards (e.g. pendant two-hand control devices) that can be
manually moved, without using tools, nearer to the hazard zone than the separation distance.
Protection against the risks from hazards arising from emissions (e.g. the ejection of solid or fluid
materials, radiation, electric arcs, heat, noise, fumes, gases) are not covered by this document.
Protection against the risks arising from failure of mechanical parts of the machine or gravity falls, are
not covered in this document.

movements, the separation distances derived from this document are not applicable.
