>TABLE> Heading C (13): Reference method of measurement 1.The reference method of measurement to be used for determining the presence of carbon tetrachloride in effluents and water is gas chromatography. A sensitive detector must be used when concentration levels are below 0,5 mg/l and in this case the determination limit(1) is 0,1 ìg/l. For concentration levels higher than 0,5 mg/l a determination limit(1) of 0,1 mg/l is acceptable. 2.The accuracy and precision of the method must be ± 50 % at a concentration which represents twice the value of the determination limit(1).
