Abstract

In this work the Proficiency Testing Scheme (PTScheme) had been used for evaluation of performance of the laboratories of automotive emissions to measure the levels of emissions of the vehicles, supplying subsidies to the laboratories in order to identify and solve analytical problems and contributing for the harmonization of the results of the measurements in the country. The PTScheme of automotive emissions is a type of study, provided only in Brazil and it can be concluded that the results have been satisfactory and of great importance for the industry, society and environment. In this work is presented a comparison of results for the four rounds held covering the period from 2004 to 2010.
