Safety of machinery - Mechanical safety data for physical contacts between moving machinery and persons (ISO/DIS 21260:2018)

This European Standard defines limits for physical contacts between machines and humans that are caused by movement of the machine as part of its intended use or foreseeable misuse. It covers all types of machines that are designed to function where people can be present without physical barriers and as a result can contact those people. It also covers hazardous mechanical contacts of humans with surroundings that are caused by human fall originated by the movement of a machine. It includes machines that contact people as part of their function and machines that do not require human contact. It encompasses interactions that are intentional or unintentional.
Machines include but are not limited to, fixed robots, mobile robots, collaborative robots, vehicles, machine tools, moving equipment, doors and powered doors, flying robots, exoskeletons, care and domestic servant robots, hand tools.
Requirements that are mandated by local, national or international regulations take precedence over this standard.
Medical devices are not covered by this European Standard.

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.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).
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. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
on the ISO list of patent declarations received (see www.iso.org/patents).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.

Introduction
The structure of safety standards in the field of machinery is as follows.
Type-A standards (basic safety standards) give basic concepts, principles for design and general
aspects that can be applied to machinery;
Type-B standards (generic safety standards) dealing with one or more safety aspect(s), or one or more
type(s) of safeguards that can be used across a wide range of machinery:
— type-B1 standards on particular safety aspects (for example, safety distances, surface
temperature, noise);
— type-B2 standards on safeguards (for example, two-hands control devices, interlocking devices,
pressure-sensitive devices, guards);
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.
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 organizations, market surveillance etc.)
It is possible to 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 standard, the requirements of that type-C standard take
precedence.

Moving machines and machines with moving parts frequently operate in close proximity to or in the
same physical space as people [e.g. train (access), lift doors, machine tools]. In most circumstances, the
moving parts of the machine make no contact with people. Indeed, wherever possible steps are taken to
prevent any contact.
There are however exceptions, for example closing powered doors or moving guards and in some cases
moving parts of machine tools that contact the operator (e.g. parts of packaging machines). Where this
is the case to prevent injury machine specific limits for the contacts are set by individual type-C
standards.
With increased use of motor driven automation and the introduction of machines that operate with
people collaboratively, machine-human contact caused by machine movements are becoming more
likely and more common.
This document defines non-machine specific limits for con
