This International Standard specifies the determination of phytase activity in feed samples.The method does not distinguish between phytase added as a feed additive and endogenous phytase alreadypresent in the feed materials,The method cannot be used to evaluate or compare the in vivo efficacy of the phytase product, It is not apredictive method of the in vivo efficacy of phytases present on the market as they can develop differentin vivo efficacy per unit of activity,The method is suitable and validated exclusively for the determination of phytase activity and exclusively incomplete feeds,NOTE The harmonized method was developed on the basis of the presently existing phytase products[E1600 (EC 3.1,3,8, 3-phytase), E1614 (EC 3,1,3,26, 4-phytase), and E1640 (EC 3.1,3,26, 4-phytase)]. Therefore, it mightnot necessarily be suitable as such for phytase products that are developed in the future, The harmonized method is thusa tool which is useful only to evaluate the total phytase activity in feed samples,
