This European Standard specifies a method for the determination of hydroxyl value of aliphatic and cyclic hydroxyl
compounds with hydroxyl groups attached to primary and secondary carbon atoms.
This European Standard is applicable to polyacetals, temperature sensitive materials, high solids polymer polyols
and rigid polyols and phenols.
This European Standard is not suitable for determination of hydroxyl groups attached to tertiary carbon atoms.
NOTE This method is currently recommended for neutral refined products. However for products that contain an excess of
acidic species a validation should be carried out to show that the acidic species either does not interfere or that the acidic
species interference has been obviated.
