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). Field Code Changed
ISO draws attention to the possibility that the implementation of this document may involve the use of
(a) patent(s). ISO takes no position concerning the evidence, validity or applicability of any claimed
patent rights in respect thereof. As of the date of publication of this document, ISO had not received
notice of (a) patent(s) which may be required to implement this document. However, implementers are
cautioned that this may not represent the latest information, which may be obtained from the patent
database available at www.iso.org/patents.www.iso.org/patents. ISO shall not be held responsible for
identifying any or all such patent rights.

This document was prepared by Technical Committee ISO/TC ISO/TC 199, Safety of machinery, in
collaboration with the European Committee for Standardization (CEN) Technical Committee
CEN/TC 114, Safety of machinery, in accordance with the Agreement on technical cooperation between
ISO and CEN (Vienna Agreement).
This third edition cancels and replaces the second edition (ISO 14119:2013), which has been technically
revised.
The main changes are as follows:
— ISO/TS 19837 has been integrated as new Annex KAnnex K with specific requirements for Type 5
interlocking devices ‑- “trapped key interlocking devices” (see definition 3.18.1);3.18.1);
— trapped key interlocking systems and type 5 interlocking devices have been defined;
Table 5— Table 5 has been improved and renamed;
— test procedures are described in new Annex I;Annex I;

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.
This document is of relevance, in particular for the follo
