Water quality. Determination of turbidity - Semi-quantitative methods for the assessment of transparency of waters has-corrigendum - Water supplies for fireWhat is this standard about? This document specifies the following semi quantitative methods for the assessment of transparency of waters: a) measurement of visual range using the transparency testing tube (applicable to transparent and slightly cloudy water); b) measurement of visual range in the upper water layers using the transparency testing disc (especially applicable to surface, bathing water, waste water and often used in marine monitoring);
