Safety of machinery - Emergency stop - Principles for design (ISO 13850:2015)

This International Standard specifies functional requirements and design principles for the emergency
stop function on machinery, independent of the type of energy used.
It does not deal with functions such as reversal or limitation of motion, deflection of emissions (e.g.
radiation, fluids), shielding, braking or disconnecting, which can be part of the emergency stop function.
The requirements for this International Standard apply to all machines, with exception to:
— machines where an emergency stop would not reduce the risk;
— hand-held or hand-operated machines.
NOTE The requirements for the realization of the emergency stop function based on electrical/electronic
technology are described in IEC 60204-1.

Sicherheit von Maschinen - Not-Halt - Gestaltungsleitsätze (ISO 13850:2015)

Diese Internationale Norm legt funktionale Anforderungen und Gestaltungsleitsätze für die Not-Halt-Funktion, unabhängig von der Art der verwendeten Energie, fest.
Sie behandelt nicht die Funktionen wie Umkehr und Begrenzen von Bewegungen, Abweisen von Emissionen (z. B. Strahlung, Flüssigkeiten), Abschirmen, Bremsen oder Unterbrechen, die Teil der Not-Halt-Funktion sein können.
Die Anforderungen dieser Internationalen Norm gelten für alle Maschinen, mit Ausnahme von:
   Maschinen, bei denen ein Not-Halt das Risiko nicht verringern würde;
   von Hand tragbaren und handgeführten Maschinen.
ANMERKUNG   Die Anforderungen zur Realisierung einer Not-Halt-Funktion, die auf einer elektrischen/elektronischen Technologie basiert, sind in IEC 60204-1 beschrieben.

Sécurité des machines - Arrêt d'urgence - Principes de conception (ISO 13850:2015)

ISO 13850:2015 spécifie les exigences fonctionnelles et les principes de conception de la fonction d'arrêt d'urgence, indépendamment du type d'énergie utilisée.
La présente Norme internationale ne traite pas des fonctions telles que l'inversion ou la limitation du mouvement, la déflexion d'émissions (par exemple, rayonnements, fluides), l'interposition d'un écran, le freinage ou la déconnexion, qui peuvent faire partie de la fonction arrêt d'urgence.
Les exigences de la présente Norme internationale s'appliquent à toutes les machines, à l'exception:
-      des machines pour lesquelles un arrêt d'urgence ne réduirait pas le risque;
-      des machines portatives tenues à la main ou machines à main.
NOTE          Les exigences relatives à la réalisation de la fonction d'arrêt d'urgence basée sur la technologie électrique/électronique sont décrites dans l'IEC 60204‑1.

Varnost strojev - Zaustavitev v sili - Načela načrtovanja (ISO 13850:2015)

Ta mednarodni standard določa funkcionalne zahteve in načela za načrtovanje funkcije
zaustavitve v sili na strojih ne glede na vrsto uporabljene energije.
Standard ne obravnava funkcij, kot so zamenjava smeri ali omejitev gibanja, odboj emisij (npr.
sevanja, tekočin), zaščita, zaviranje ali odklop, ki so lahko del funkcije zaustavitve v sili.
Zahteve za ta mednarodni standard se uporabljajo za vse stroje z izjemo:
— strojev, pri katerih zaustavitev v sili ne bi zmanjšala tveganja;
— ročnih ali ročno upravljanih strojev.
OPOMBA: Zahteve za realizacijo funkcije zaustavitve v sili na podlagi električne/elektronske
tehnologije so opisane v standardu IEC 60204-1.

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.

assessment, as well as information about ISO’s adherence to the WTO principles in the Technical

Barriers to Trade (TBT) see the following URL: Foreword - Supplementary information

Introduction
The structure of safety standards in the field of machinery is as follows.

a) Type-A standards (basic safety standards) give basic concepts, principles for design, and general

aspects that can be applied to machinery.

b) Type-B standards (generic safety standards) deal with one or more safety aspect(s) or one or more

type(s) 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-hands controls, interlocking devices, pressure

sensitive devices, guards).

c) Type-C standards (machinery safety standards) deal with detailed safety requirements for a

particular machine or group of machines.
This International Standard is a type-B2 standard as stated in ISO 12100.

When provisions of a type-C standard are different from those which are stated in type-A or type-B

standards, the provisions of the type-C standard take precedence.

Safety of machinery — Emergency stop function —
Principles for design
1 Scope

This International Standard specifies functional requirements and design principles for the emergency

stop function on machinery, independent of the type of energy used.

It does not deal with functions such as reversal or limitation of motion, deflection of emissions (e.g.

radiation, fluids), shielding, braking or disconnecting, which can be part of the emergency stop function.

The requirements for this International Standard apply to all machines, with exception to:

— machines where an emergency stop would not reduce the risk;
— hand-held or hand-operated machines.

NOTE The requirements for the realization of the emergency stop function based on electrical/electronic

technology are described in IEC 60204-1.

4 Safety requirements
4.1 General requirements
4.1.1 Emergency stop function

4.1.1.1 The purpose of the emergency stop function is to avert actual or impending emergency

situations arising from the behaviour of persons or from an unexpected hazardous event.

The emergency stop function is to be initiated by a single human action.

4.1.1.2 The emergency stop function shall be available and operational at all times. It shall override all

other functions and operations in all operating modes of the machine without impairing other protective

functions (e.g. release of trapped persons, fire suppression).
When the emergency stop function is activated:
— it shall be maintained until it is manually reset;
— it shall not be possible for any start command to be effective on those operat
