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.

Introduction

Tyre and road wear particles (TRWP) are formed from the friction between a tyre and roadway surface. The particles are subsequently released into nearby soil and sediment ecosystems. As such, there is interest in studying the composition and effects of TRWP on the environment (Kreider et al. 2010; Unice et al. 2015). This document provides guidelines for the generation of TRWP using a road simulator in a laboratory setting. The guidelines describe the method, apparatus and equipment, TRWP collection procedures, monitoring measures, and test report. An informative case study is also provided.

Generation of TRWP with a road simulator eliminates interferences from other roadway surface contaminants such as brake dust, oil and grease, soil, and vegetation (Kreider et al. 2010). This method allows for a more accurate characterization of the physical and chemical properties of TRWP than other generation methods including on-road collection and cryogenic breaking of rubber tread. In addition, a greater mass of TRWP can be collected using the road simulator laboratory method. Other laboratory generation methods (e.g., steel brush and grit paper) are not representative of actual driving conditions and may introduce additional interferences to the generated TRWP. Furthermore, previous analysis has shown that the particle morphology and size distribution of TRWP generated using on-road and road simulator methods are similar, with the on-road TRWP slightly smaller in size (Kreider et al. 2010).

Annex A gives information on a case study of TRWP generation.

1 Scope

This document specifies a method for the generation of tyre and road wear particles (TRWP) in a road simulator laboratory that is representative of actual driving conditions. Guidance is provided for the road simulator system, test pavement and tyres, vacuum collection system, monitoring, and reporting.

This method is applicable for the collection of TRWP from a known pavement and tyre type under realistic driving conditions without the inference of road surface contaminants (i.e. brake dust, exhaust, grease, etc.).

There is a possibility that this method is not relevant for studded tyres.
