This standard describes a procedure for the determination of unsaponifiable and saponifiable matter in blends of mineral and fatty oils. The procedure is also suitable for essentially fatty materials. If present the free fatty acids are included in the saponifiable matter. If required the fatty acids and the unsaponifiable matter isolated can be examined for identification. The procedure described is not suitable for materials that contain: — products saponifiable with difficulty, such as certain waxes, resins or esters of high fatty acids that form sparingly soluble potassium salts; — unsaponifiable constituents of high melting point and low solubility in diethyl ether: — highly polymerized fatty oils that form emulsions that can only be separated with difficultly.
