ISO 4629-2:2016规定了用于测定树脂，油漆和清漆的粘合剂，伯醇，二醇和脂肪的羟值的滴定法。是否可以应用于羧酸，酚羟基，多元醇如三甲基丙烷和含芳香族基团的物质已经被激活，用于Friedel-Crafts酰化应根据具体情况决定。 在适当的条件下，该方法也适用于测定蓖麻油及其衍生物的羟值

ISO 4629-2:2016 specifies a titrimetric method for determining the hydroxyl value of resins, binders for paints and varnishes, primary alcohols, glycols and fats. Whether it can be applied for hydro carboxylic acids, phenolic hydroxyl groups, polyols such as trimethyl propane and substances containing aromatic groups have been activated for Friedel-Crafts acylation shall be decided on case-to-case basis. Under the right conditions, the method is also applicable for determining the hydroxyl value of castor oil and its derivatives.
