ISO 22160 | IDF 209:2007规定了使用化学发光（EPAS）法测定巴氏杀菌全脂牛奶、半脱脂牛奶、脱脂牛奶、奶油和调味牛奶中碱性磷酸酶活性的方法。 该方法适用于奶牛、绵羊、水牛和山羊的牛奶和奶基饮料。 如果以稀释碱性磷酸酶活性低于每升7000毫单位的方式稀释，则该方法也适用于任何液体样品。

ISO 22160|IDF 209:2007 specifies a method for the determination of the alkaline phosphatase activity in pasteurized whole milk, semi-skimmed milk, skimmed milk, cream and flavoured milks using a chemiluminescent (EPAS) method. The method is applicable to milk and milk-based drinks from cows, sheep, buffalo and goats. The method is also suitable for any liquid-based sample if diluted in such a way that the diluted alkaline phosphatase activity has less than 7 000 milliunits per litre.
