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, 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, 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 ).

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.

1 Scope

This document gives the specifications for impact attenuation testing equipment used to evaluate the impact performance characteristics of playground surfacing. The specifications are aimed at ensuring that developers and manufacturers of such instruments meet minimum performance characteristics to allow repeatable, reproducible and accurate results.

This document does not specify a test method.
