BS 2000-107:1993

This standard BS 2000-107:1993 Methods of test for petroleum and its products is classified in these ICS categories:

• 75.160.20 Liquid fuels

1.1. This method covers the determination of total sulphur in liquid petroleum products in concentrations above 0.002 % by weight [Note 1]. A special sulphate analysis procedure is described in Appendix I that permits the determination of sulphur in concentrations as low as 5 ppm.

NOTE 1: The comparable lamp method for the determination of sulphur in fuel gases is described in ASTM Method D 1072. For the determination of sulphur in heavier petroleum products that cannot be burned in a lamp, see the bomb method (ASTM D129–IP61), or the high-temperature method (ASTM DI 552).²

1.2. The direct burning procedure (Section 7) is applicable to the analysis of such materials as gasoline, kerosine, naphtha, and other liquids that can be burned completely in a wick lamp. The blending procedure (Section 8) is applicable to the analysis of some materials that cannot be burned satisfactorily by the direct procedure, such as gas oils, distillate fuel oils, naphthenic acids and alkyl phenols. Residual fuel oils, bitumens, tars and other heavy residues CANNOT be analysed by this method.

1.3. Phosphorus compounds normally present in commercial gasoline do not interfere. A correction is given for the small amount of acid resulting from the combustion of the lead anti-knock fluids in gasolines. Appreciable concentrations of acid-forming or baseforming elements from other sources interfere when the titration procedure is employed since no correction is provided in these cases.

Identical with IP 107/86.
