Automotive particle emissions: dissemination of aerosol measurement expertise to standards bodies

This project ensured that SI traceability and measurement good practice in the area of airborne particle number concentration measurement was incorporated into the relevant CEN and ISO standards and PMP (Particle Measurement Programme) documents. This should enable a more efficient and reliable implementation of the regulations covering particle emissions from vehicles (Regulation No 83 of the UN/ECE), whilst also supporting similar measurements in other areas like air quality.
