In thesecond revision the Iirnit for iodine value is being changed from 175 Min to170 Min in view of the data available and the experience gained. Thischange brings this requirement in line with the provisions of thePrevention of Food Adulterat ion Act, 1952 of the Government of India.
0.4 The pharrnaccurical grade of linseed oil is covered in Pharmacopoeiaof India ('The Indian Pharrnacopoeia ). The Raw Grade 2, specifiedin this standard, corresponds to this grade. The boiled and pale-boiledtypes of linseed oils are covorr-d in IS: i7-1 ~68§.
