BS 6069 3. 3 specifies a charcoal tube gas chromatographic method for the determination of the concentration of vaporous chlorinated hydrocarbons in workplace air. The method described in BS 6069 3. 3 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.
