Abstract
A program is described whereby more than 100 US and foreign laboratories have participated in a quality assurance technique meant to improve the accuracy and consistency in the measurement of vehicle exhaust emissions. Every three months each laboratory received as many as four multicomponent gas samples. Analytical measurements were made on 100% of the samples to assure homogeneity. Regardless of analyte or concentration, component consistency checks were typically 0.3% or less.
