This European Standard describes the analytical requirements for the determination of particulate diesel engine exhaust emissions in workplace atmospheres. The particulate concentration, averaged over the sampling duration is determined by the parameters total carbon, organic carbon and elemental carbon.This European Standard enables users to determine occupational exposure to DPM according to a uniform approach and to obtain directly comparable results.It is the responsibility of users to ascertain that the requirements of EN 482 under the given laboratory conditions are fulfilled.Potential procedure-related cross sensitivities and interferences in particular workplaces mentioned in this European Standard have to be particularly considered.
