ISO 2554:1997, Plastics - Unsaturated polyester resins - Determination of hydroxyl value

This International Standard specifies a method for determining the hydroxyl value of unsaturated polyester resins.In fact, this method determines the difference between the hydroxyl value and the acid value; it is therefore necessary to determine the total acid value separately, in order to calculate the hydroxyl value.
