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.
For an explanation of the voluntary nature of standards, the meaning of ISO specific terms and
expressions related to conformity assessment, as well as information about ISO's adherence to the
World Trade Organization (WTO) principles in the Technical Barriers to Trade (TBT), see www .iso
.org/iso/foreword .html.
This document was prepared by Technical Committee ISO/TC 127, Earth-moving machinery,
Subcommittee SC 2, Safety, ergonomics and general requirements.
This first edition of ISO 19014-1, together with ISO 19014-2, ISO 19014-3, ISO 19014-4 and ISO/
TS 19014-5, cancels and replaces ISO 15998 and ISO/TS 15998-2, which have been technically revised.
The main changes compared to the previous documents are as follows:
— method for determination of performance levels and machine control system safety analysis,
— additional requirements for mobile machines,
— environmental test requirements for components of safety controls systems, and
— requirements for software validation and verification of machine performance levels.
This corrected version of ISO 19014-1:2018 incorporates the following corrections:
— in 4.2 c) 2), 4.2 d) 1), 6.1 and Annex C, the cross-references to the steps defined in 4.2 have been
corrected.
A list of all parts in the ISO 19014-series can be found on the ISO website. At the time of publication of
this document, Part 2, Design and evaluation of safety-related machine control systems, Part 4, Design and
evaluation of software and transmission for safety related parts of the control system, and Part 5, Tables of
performance levels, are under development.
Any feedback or questions on this document should be directed to the user’s national standards body. A
complete listing of these bodies can be found at www .iso .org/members .html.
