Abstract: | The Light Duty Inter-Laboratory Correlation Exercise (ILCE) final report, performed with the ‘PMP Golden Vehicle’ at nine
laboratories in the EU, Korea and Japan to demonstrate repeatability and reproducibility of the particle number concentration
emissions measurement techniques proposed by the Particle Measurement Program (PMP), was released in 2007. The ILCE was conducted
by the Korea Particle Measurement Program (KPMP) with a domestic diesel passenger vehicle equipped with a diesel particulate
filter (DPF) between three certification laboratories and the research center of an automotive manufacturer to meet future
regulations (EURO 5 and EURO 6) of particle number concentration for light-duty vehicles in early 2008. This research focused
on measuring the particulate matter emission (particle number and mass) levels of a representative light-duty diesel passenger
vehicle during new European driving cycle (NEDC) mode to analyze the repeatability and reproducibility between laboratories
in Korea. From the ILCE test results in Korea, the mean total particle number concentration levels ranged from 5.43E+10 #/km
to 1.58E+11 #/km and 0.0003 g/km to 0.0036 g/km for particle mass. Repeatability between participating laboratories ranged
from 32% to 66% for particle number, 11% to 70% for particle mass; the reproducibility level was 46% for particle number,
and 66% for particle mass emission.
