ISO 15174:2012 is an International Standard that outlines a method for determining the total milk-clotting activity of microbial coagulants. It specifically compares the activity of a sample coagulant to an international reference standard on a standardized milk substrate. The reference standard is a powder derived from R. miehei and is calibrated against an initial batch of international calf rennet reference standard powder.
