Discussion document as revised during the 29th PMP session.

Presentation concerning the measurement of sub23 nm vehicle emissions particles.

Review of data and conclusions from the World Business Council for Sustainable Development (WBCSD) Tire Industry Project study on airborne tire and road dust particles. Established in January 2006, the goal of the Tire Industry Project (TIP) is to identify and address the potential health and environmental impacts of materials associated with tire making and use. This project is chaired by the three largest tire manufacturers – Bridgestone (Japan), Goodyear (US) and Michelin (France) – and includes a total of eleven companies representing approximately 70% of the world’s tire manufacturing capacity.

Overview of literature related to particle emissions from tire and/or brake wear regarding importance of such particle emissions, physico-chemical characteristics, and possible health effects.

Review of current evidence concerning risks from non-exhaust vehicle emissions and open questions regarding the potential value of a regulatory response.

This document describes the calibration and validation procedures for the VPR. Calibration of the VPR is to be performed at the point of manufacture and validation is to be performed at least at 6 month intervals for all instruments without automatic temperature sensors or at least at 12 month intervals if automatic temperature sensors are present. The calibration procedure must be repeated if the system ‘fails’ its validation procedure or the particle number measurement system is modified in any way.

Review of findings from the review of literature on particle emissions from non-exhaust sources covering tires and brake materials.

Presentation on REBRAKE, the European Commission-supported project to better understand brake-wear emissions and their impact on air quality.

Discussion presentation on issues potentially impacting the measurement of PN during regeneration of gasoline particulate filters and diesel particulate filters on light-duty vehicles.

Draft copy for PMP informal group comment of the JRC Science and Policy Report.

Summary of the PN calibration project under the European Metrology Research Programme’s project on “emerging requirements for measuring pollutants from automotive exhaust emissions” (EMRP ENV-02).

Presentation on Swedish and Scandinavian research into sources and impact of non-exhaust airborne particles, including from wear on roads, tires, brakes, and similar sources.

Discussion paper considering how to proceed in further investigations into non-exhaust emissions (tire, friction materials) from motor vehicles towards defining measurement procedures.

Russian position paper on non-exhaust emissions from motor vehicles and road surfaces.

Proposal to replace Directive 97/68/EC with an updated and more appropriate regulation, including expansion of the scope to include additional engine categories and to adapt the emission stages last amended in 2004 to the current state of technology. Furthermore, the regulation would address mismatches between emission limits and certain engine categories.

Copy of a presentation on the revision of Directive 97/68/EC on non-road mobile machinery engine type approval and emissions limits.

Presentation on the EU 7th Framework project to 1) reduce brake-related PM10 emissions by at least 50% in compliance with the EU2020 thematic strategy of 47% reduction of particulate matter by 2020; and 2) to build a deeper understanding of the physical and chemical phenomena underlying the brake wear process, including higher comprehension and analysis of characteristics coarse, fine and UFP particles.
