- Scope
- This standard specifies a titrimetric method of determining the hydroxyl value of resins, paint and varnish raw materials, primary alcohols, glycols and fats. Whether it can be applied to hydroxycarboxylic acids, phenolic hydroxyl groups, polyols such as trimethylolpropane and substances containing aromatic groups that have been activated for FriedeI-Crafts acylations shall be decided on a case-by-case basis.Under the right conditions, the method is also suitable for determining the hydroxyl value of castor oil and its derivatives.
