GB/T 7782-2008 in English

《GB/T 7782-2008计量泵》由TC211（全国泵标准化技术委员会）归口，主管部门为中国机械工业联合会。
本标准是对ＧＢ／Ｔ７７８２―１９９６《计量泵》的修订。本标准规定了计量泵的信息确认、要求、试验和检验、交付准备、标志、包装及贮存。本标准适用于输送温度为-30℃～150℃、粘度为0.3 mm2/s～2000mm2/s的液体的柱塞计量泵和隔膜计量泵。输送含固体颗粒液体的柱塞计量泵不适用于本标准。 与ＧＢ／Ｔ７７８２―１９９６相比，主要有如下变化：
―――测量不确定度的计算采用ＧＢ／Ｔ７７８４；
―――删除部分产品设计过程上的技术要求；
―――增加了信息确认和交付准备的要求；
―――部分参数的数据处理采用ＧＢ／Ｔ７７８４。
