BS 4267 discusses ammonium nitrate. BS 4267-4 is the fourth part of the BS 4267 multi-series and discusses the determination of sulphated ash.
BS 4267-4 describes a gravimetric method for the determination of the sulphated ash of ammonium nitrate for industrial use. The method is applicable to products with sulphated ash of not less than 0.1 % (m/m).
BS 4267-4 on sulphated ash of ammonium nitrate is useful for:
Ammonium nitrate is used commonly in fertilizers, pyrotechniques, herbicides, and insecticides, and in the manufacture of nitrous oxide. It is used as an absorbent for nitrogen oxides, an ingredient of freezing mixtures, an oxidizer in rocket propellants, and a nutrient for yeast and antibiotics
BS 4267-4 provides you with reagents and apparatus required for the test procedure. BS 4267-4 guides you with the procedure and expression of the results of the test. BS 4267-4 enables you to identify sulphated ash of ammonium nitrate suitable for industrial use.
