This European Standard specifies parameters which can be used for the assessment of the emission of pollutants from machines or the performance of the pollution control systems integrated in machines. It gives guidance on the selection of appropriate test methods according to their various fields of applications and types of machines including the effects of measures to reduce exposures to pollutants. The test methods are given in additional parts of this standard (see Table 1 and Annex A). This European Standard is not applicable for certain types of off-the-road vehicles powered by internal combustion engines which are also subject to the Machinery Directive.
