Summary This standard specifies two methods for measuring water turbidity. First spectrophotometry, suitable for drinking water, natural water and high turbidity water, minimum detectable turbidity of 3 degrees. The second visual turbidimetry, and water suitable for drinking water and other low-turbidity water, minimum detectable turbidity of 1 degree. Water should be free of debris and easy to sink particles as dirty utensils or water has dissolved bubbles and colored substances interfere with the determination.
