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 83, Sports and other recreational facilities

and equipment.

Any feedback or questions on this document should be directed to the user’s national standards body. A

ISO/TR 24666:2021(E)
Introduction

This document summarizes information about different regional and national standards on playground

safety in order to provide a reference point for different types of entrapments and probes/gauges.

Some standards apply to entrapment tests universally, regardless of the intended user age group, on the

basis that it is very difficult to control users when products are installed in a free access environment.

Other standards apply to specific entrapment probe tests related to specific intended user age groups.

In cases where user age references are provided in the standard, see in Annex A to Annex H.

TECHNICAL REPORT ISO/TR 24666:2021(E)
Sports and recreational facilities — Probes for
entrapment/entanglement on playground equipment —
Collection of data
1 Scope

This document compiles a collection of different probes/gauges for assessing common playground

equipment safety performance to eliminate known safety hazards such as: entrapment and

entanglement hazards on playground, playspaces, and associated equipment used in different

countries/regions around the world. It also explains some historical content of origins, the purpose and

some rationales for the dimensions and shape of each of those probes.

NOTE These test probes and gauges, their dimensions and related historic rationale for their existence are of

significant value to playground equipment, manufacturers, designers, installers, assemblers, owners, operators

and inspectors alike and are necessary tools to the reduction of serious, life-threatening and debilitating injuries

to the public playground intended users.
