ISO 10523 pH Measurement of Water for Quality Compliance: A Comprehensive Guide

The ISO 10523 standard is a widely accepted international standard for the measurement of water pH, which is essential for ensuring the quality compliance of water in various industries. This standard is published by the International Organization for Standardization (ISO) and provides a framework for laboratories to conduct pH measurements with high accuracy and reliability.

Legal and Regulatory Framework

The ISO 10523 standard is governed by the following regulations:

  • European Unions Drinking Water Directive (98/83/EC)
  • United States Environmental Protection Agencys (EPA) Safe Drinking Water Act
  • World Health Organizations (WHO) guidelines for drinking-water quality
  • These regulations require laboratories to conduct pH measurements in accordance with the ISO 10523 standard, ensuring that water samples meet the required quality standards.

    International and National Standards

    The following international and national standards apply to the ISO 10523 pH Measurement of Water for Quality Compliance testing:

  • ISO 10523:2017 - Water quality - Determination of pH
  • ASTM D1064-14 - Standard Test Method for pH of Aqueous Solutions
  • EN ISO 10523:2012 - Water quality - Determination of pH
  • TSE 620/2-2015 - Turkish Standards Institutions standard for water quality determination of pH
  • Standard Development Organizations

    The ISO 10523 standard is developed and maintained by the following organizations:
