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 254, Safety of amusement rides and
amusement devices.
This second edition cancels and replaces the first edition (ISO 17842-3:2015), which has been
technically revised.
The main changes are as follows:
— references to ISO/TS 17929 have been removed;
— a reference to ISO 17842-1 has been added to 4.1.2, Review of design documents
— point g has been added to 4.1.3.1 Description;
— 4.1.3.3, Initial inspection and testing, has been updated;
— 4.2, Pre-use inspection and review – Procedures, has been added;
— 4.4, Installation examination, has been added;
A list of all parts in the ISO 17842 series can be found on the ISO website.
Any feedback or questions on this document should be directed to the user’s national standards body. A

ISO/FDIS 17842-3:2021(E)
All safety-relevant design documents as well as the completed amusement device shall be subject
to review and inspection. After a successful inspection, a document confirming conformance with
ISO 17842-1 and ISO 17842-2 can be issued.
The results of the various reviews, inspections and tests shall become an integral part of the amusement
device log.
The initial approval of the amusement device shall comprise:
a) design review,
b) inspection of manufacturing process, and
c) initial inspection and testing.
4.1.2 Review of design documents
The review of design documents is an inspection of relevant design documents.
The design documents shall, where relevant, be reviewed, checked and accepted by an independent
body for:
— completeness,
— correctness of all the assumptions with respect to the input values for any analyses,
— correctness of all calculations, and
— compliance with applicable standards and specifications.
The design documents shall where relevant include the following:
— design risk assessment;
— design calculations;
— stress and fatigue analysis and stability verification;
— structural and mechanical parts;
— hydraulic and pneumatic parts;
— drive units, bearings;
— brakes and safety devices;
— design drawings;
— acceleration/containment details, according to ISO 17842-1;
— hydraulic/pneumatic specification;
— electrical/electronic specification including software details;
— mechanical/structural specification;
— installation, operation, maintenance and inspection information;
See ISO 17842-1:2015, 4.4, for the principles of structural analysis.
