適用范圍：This International Standard specifies a method for the determination of the alkaline phosphatase activity inpasteurized 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 alkalinephosphatase activity has less than 7 000 milliunits per litre.NOTE There has been a successful collaborative trial with cow, sheep, buffalo, and 9oat whole milk, as well asskimmed cow milk (< 0,5 % fat), 20 % fat cream and 2 % fat chocolate milk (all mass fractions).
