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

ISO 24667:2021(E)
Introduction

Impact attenuating surfacing has been shown to be fundamental to the prevention of 60 % to 75 %

of the injuries in playgrounds from impacts with the surface after a fall. The surface materials can be

sourced and installed locally, such as sand, wood chips or rounded gravel, while others can be sourced

from materials around the world and assembled on site such as poured in place rubber, tiles, mats or

synthetic turfs and installed at local playgrounds. The performance of installed surfacing materials

should be comparable from playground to playground no matter where the playground is situated. The

equipment used to measure the performance of playground surfacing is internationally consistent,

repeatable and reproducible.

The field of impact attenuation measurement as it applies to playground safety surfaces is very small,

resulting in a limited market for potential manufacturers of such equipment. While a small number of

reputable manufacturers exist, organizations needing playground impact test equipment, such as test

laboratories and university researchers, often rely on their own technical abilities or those of related

engineering departments to create the needed equipment from scratch.
