BS EN 14662 3 is the third part of the multi series standard that specifies a semi continuous measurement method for the determination of the concentration of benzene present in ambient air based on automated sampling and analysis by gas chromatography. The method described in BS EN 14662 3 applies to the determination of the mass concentration of benzene present in ambient air in the range up to 50 g m3
