《GB/T 6904-2008工业循环冷却水及锅炉用水中pH的测定》由TC63（全国化学标准化技术委员会）归口，TC63SC5（全国化学标准化技术委员会水处理剂分会）执行，主管部门为中国石油和化学工业联合会。
本标准规定了工业循环冷却水及锅炉用水中pH的测定方法，适用于工业循环冷却水及锅炉用水中pH在0～14范围内的测定，还适用于天然水、污水、除盐水、锅炉给水以及纯水的pH的测定。本标准同时代替ＧＢ／Ｔ１５８９３．２―１９９５《工业循环冷却水中ｐＨ的测定　电位法》、ＧＢ／Ｔ６９０４．１―１９８６《锅炉用水和冷却水分析方法　ｐＨ的测定　玻璃电极法》和ＧＢ／Ｔ６９０４．３－１９８６《锅炉用水和冷却水分析方法　ｐＨ的测定　用于纯水的玻璃电极法》。
本标准将ＧＢ／Ｔ１５８９３．２―１９９５、ＧＢ／Ｔ６９０４．１―１９８６和ＧＢ／Ｔ６９０４．３―１９８６进行了合并。
本标准与ＧＢ／Ｔ１５８９３．２―１９９５、ＧＢ／Ｔ６９０４．１―１９８６和ＧＢ／Ｔ６９０４．３―１９８６相比在技术内容上没有差异。

Scope

This standard specifies the method for the determination of pH in industrial circulating cooling water and boiler water. This standard is applicable to the determination of the pH value of industrial circulating cooling water and boiler water within the range of 0 to 14. This standard is also applicable to the determination of the pH of natural water, sewage, demineralized water, boiler feed water and pure water.
