What is BS 6069-3.4 – Characterization of air quality about?

BS 6069-3.4 specifies a charcoal tube/gas chromatographic method for the determination of the concentration of vaporous aromatic hydrocarbons in workplace air. The method described in BS 6069-3.4 is valid for concentrations of airborne vapours of these compounds in the range from approximately 1 mg/m3 to 1 000 mg/m3 (about 0,2 ml/m3 to 200 ml/m3; see 8.1) when sampling 10 litres of air. BS 6069-3.4 cannot be used to measure instantaneous or short-term fluctuations in concentrations. Alternative on-site procedures, suc...
