BS 6068 2. 12 specifies methods for determining the phenol index (3. 2) in waters, surface waters, and wastewaters. After a preliminary distillation, the test samples are analyzed according to the specific application as follows: Method A (direct colorimetric method): This method is capable of measuring the phenol index in test samples that contain more than 0,10 mg in the
