《GB/T 2678.2-2008纸、纸板和纸浆水溶性氯化物的测定》由TC141（全国造纸工业标准化技术委员会）归口，主管部门为中国轻工业联合会。
本标准是对ＧＢ／Ｔ２６７８．２―１９９４《纸浆、纸和纸板水溶性氯化物的测定（硝酸汞法）》和ＧＢ／Ｔ２６７８．５―１９９６《纸、纸板和纸浆水溶性氯化物的测定（硝酸银电位滴定法）》的修订，并将两项国家标准进行整合。本标准规定了纸、纸板和纸浆水溶性氯化物的硝酸汞测定法和硝酸银电位滴定测定法。硝酸汞法适用于各种纸、纸板和纸浆。硝酸银电位滴定法适用于电气用纸和一般用纸。
本标准代替ＧＢ／Ｔ２６７８．２―１９９４和ＧＢ／Ｔ２６７８．５―１９９６。
本标准与ＧＢ／Ｔ２６７８．２―１９９４、ＧＢ／Ｔ２６７８．５―１９９６相比主要变化如下：
―――增加了精密酸度计及分析天平两种仪器；
―――增加了对所用的玻璃器皿和其他接触到试样或抽提液的仪器、工具均应按规定进行浸泡、煮沸和清洗的内容。
