適用范圍：This part of EN 14662 is in accordance with the generic methodology selected as the basis of the European Union for the determination of benzene in ambient air [1] for the purpose of comparison of measurement results with limit values with a one-year reference period. This part of EN 14662 gives general guidance for the sampling and analysis of benzene in air, by diffusive sampling, solvent desorption and capillary gas chromatography. This part of EN 14662 is valid for the measurement of benzene in a concentration range of approximately 0,5 ug/m
