1.1 This standard lays down the methods of sampling and test for individual oils, fats and fatty materials. It contains definitions of terms used in trade and industry and prescribes the methods for determining moisture, insoluble impurities, acid value and free fatty acids, unsaponifiable matter, melting point, refractive index, specific gravity, titre of mixed fatty acids, colour, iodine value (Wijs), saponification value, acetyl value and hydroxyl value, allyl isothiocyanate content, Reichert-Meissl value and Polenske value.
1.2 Test methods, neither prescribed in this standard nor specified in standards for individual materials, shall be subject to agreement between the purchaser and the supplier.
1.3 Should any inconsistency be found to exist between the methods prescribed in this standard and those prescribed in the standard for an individual material, the latter shall prevail.
