Safety of amusement rides and amusement devices — Part 1: Design and manufacture
This document specifies the minimum requirements necessary to ensure the safe design, calculation, manufacture and installation of mobile, temporary or permanently installed amusement ride machinery and structures, which are intended for use by persons as a leisure activity. The amusement rides and amusement devices include for example, roundabouts, swings, boats, Ferris wheels, roller coasters, chutes, booths, side shows and structures for artistic aerial displays. They are intended to be installed both repeatedly without degradation or loss of integrity, and temporarily or permanently in fairgrounds and amusement parks or any other locations. This document is not applicable to grandstands, construction site installations, scaffolding, removable agricultural structures, simple coin operated children’s amusement devices, carrying up to three children, and recreational devices like waterslides or summer toboggan runs, playground equipment, rope courses, climbing wall, inflatable, trampolines, swimming pool equipment, etc. NOTE For all the equipment not covered by the requirements of ISO 17842-1, the relevant standards apply. Nevertheless, this document can be used in the design of any similar structural or passenger carrying amusement device not explicitly mentioned herein.

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 document 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).
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. ISO shall not be held responsible for identifying any or all
such patent rights.
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 17842-1:2015), which has been technically
revised.
The main changes are as follows:
— the normative references have been updated;
— the terms and definitions have been revised;
— alignment with EN 13814 series from 2019;
— the general risk assessment has been supplemented by the operator-side risk assessment;
— the safety distances of passenger units have been fundamentally revised;
— the requirements for personal restraint systems have been supplemented by additional monitoring;
— new Annex I contains the acceleration effects on passengers to align with ASTM F2291-21.
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
complete listing of these bodies can be found at www.iso.org/members.html.

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 document 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).
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. ISO shall not be held responsible for identifying any or all
such patent rights.
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 17842-1:2015), which has been technically
revised.
The main changes are as follows:
— the normative references have been updated;
— the terms and definitions have been revised;
— alignment with EN 13814 series from 2019;
— the general risk assessment has been supplemented by the operator-side risk assessment;
— the safety distances of passenger units have been fundamentally revised;
— the requirements for personal restraint systems have been supplemented by additional monitoring;
— new Annex I contains the acceleration effects on passengers to align with ASTM F2291-21;
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

FINAL DRAFT INTERNATIONAL STANDARD ISO/FDIS 17842-1:2023(E)
Safety of amusement rides and amusement devices —
Part 1:
Design and manufacture
1 Scope
This document specifies the minimum requirements necessary to ensure the safe design, calculation,
manufacture and installation of mobile, temporary or permanently installed amusement ride
machinery and structures, which are intended for use by persons as a leisure activity. The amusement
rides and amusement devices include for example, roundabouts, swings, boats, Ferris wheels, roller
coasters, chutes, booths, side shows and structures for artistic aerial displays. They are intended to be
installed both repeatedly without degradation or loss of integrity, and temporarily or permanently in
fairgrounds and amusement parks or any other locations.
This document is not applicable to grandstands, construction site installations, scaffolding, removable
agricultural structures, simple coin operated children’s amusement devices, carrying up to three
children, and recreational devices like waterslides or summer toboggan runs, playground equipment,
rope courses, climbing wall, inflatable, trampolines, swimming pool equipment, etc.
NOTE For all the equipment not covered by the requirements of ISO 17842-1, the relevant standards apply.
Nevertheless, this document can be used in the design of any similar structural or passenger carrying
amusement device not explicitly mentioned herein.
