ISO 10523:2008 specifies a method for determining the pH value in rain, drinking and mineral waters, bathing waters, surface and ground waters, as well as municipal and industrial waste waters, and liquid sludge, within the range pH 2 to pH 12 with an ionic strength below I = 0,3 mol/kg (conductivity at 25 °C
Abstract
Overview
ISO 10523:2008 - "Water quality - Determination of pH" defines an electrometric method for measuring the pH of a wide range of water matrices using pH glass electrodes. The standard covers measurements in rain, drinking and mineral waters, bathing waters, surface and ground waters, municipal and industrial waste waters, liquid sludge and similar samples. Measurement range is , for ionic strength below and temperatures between . The document includes procedural requirements, sampling guidance and informative annexes on buffer preparation, field and flow-system measurements, low ionic strength waters and performance data.
