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.

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

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;

4 Requirements
4.1 Initial approval — Procedures
4.1.1 General
The initial approval of any amusement device consists of review, inspections and tests to be carried out
as follows.
The inspection body performing the initial approval shall operate in accordance with ISO/IEC 17020.
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.
4.1.3 Inspection of manufacturing process
4.1.3.1 Description
The inspection for the hereafter stated manufacturing requirements shall be made, when appropriate,
during the manufacturing process and completed before the permit to operate with passengers. As a
general requirement, the conformance of the parts, assemblies, components as well as their assembly
and combined effects within the entire installation shall be confirmed with respect to the approved
design documents.
This shall be covered by a report which confirms correctness and suitability of the employed materials
and correctness of assembly.
The report can make reference to the manufacturer’s inspection documents, quality system and/or
declarations as part of the proof of conformity.
4.1.3.2 Inspection requirements
Inspection shall, as a minimum, verify the following:
a) conformity of the main dimensions, clearance distances and dimensions, free (easy) running of
moving parts;
b) existence of all constructional components indicated in the construction documents;
c) conformity with the major dimensions of the load-carrying constructional components and
their connections. Inaccessible constructional components or component groups are only to be
dismantled when there are doubts concerning the compliance of the dimensions or the correct
assembly/mounting;
d) conformity with the weight on which the calculations are based for such parts whose excess weight
would cause the permissible stress on connections or constructional components to be exceeded,
or whose shortage in weight might affect the safety of the equipment as far as lifting-off, sliding or
tilting-over are concerned;
e) conformity of the required certificates concerning material specification and quality, e.g. strength,
durability, fire resistance;
f) conformity of the electrical, electronic, hydraulic/pneumatic equipment with wiring, circuit
diagrams, including when possible software, observance of the relevant national or regional
standards and/or IEC standards and the applicable regulations or standards;
g) conformity with welding procedures specifications, shaping, machining, thermal treatment,
coating of the structural and safety related parts by NDT.
The inspection of bearings, motors, enclosed drive units, switch and control units and similar
components is required for, and limited to, only such cases where their failure could affect the safety of
persons.
4.1.3.3 Initial inspection and testing
The initial inspection and testing shall consist of a number of separate inspections and tests which,
taken together, demonstrate that at the time and place of the testing and inspection, the amusement
device is capable of performing in accordance with the approved design documents. Functional tests
concerning the movements unloaded and under full load are required. Unbalanced load tests are to be
made in accordance with ISO 17842-1:2015, 4.4.2.1. See also ISO 17842-1:2015, 4.3.3.1.2.1 for test loads.
During the trial run, the following functions and conditions shall be checked, as applicable:
— clearance envelope for passengers relative to any moving parts or other objects (see ISO 17842-1);
— correct working of sequential, forced and interlocked control systems;
— the specified speeds, accelerations and safety critical weights e.g. ballast, counterweights;
— the working pressures of hydraulic/ pneumatic systems;
— the correct connection of electric supply;
— the setting of inclination
