This standard describes the determination of suspended solids in raw waters, waste waters and effluents by filtration through glass fibre filters. The lower limit of the determination is 2 mg/l. Finely dispersed or colloidal matter may escape filtration and not be included in the reported value. Water samples are not always stable which means that the content of suspended solids depends upon storage time, means of transportation, pH value and other circumstances. Results obtained with unstable samples should be interpreted with caution. Floating oill and other immiscible organic liquids will interfere. Samples containing more than about 1000 mg/l of dissolved solids may require special treatment.
