GSO 1206:2002 Scope

1.1 This Gulf standard is concerned with the determination of basic number in petroleum products by titration with perchloric acid in glacial acetic acid. 1.2 Procedures A and B use different titration solvent volumes and sample weights. Note (1): A round robin on a series of new and used oils and additive concentrates has shown that the two procedures give statistically equivalent results. 1.3 Appendix B provides the use of an alternative solvent system which eliminates the use of chlorobenzene in this test method. These of the alternative solvent gives statistically equivalent results; however, the precision is worse. Paragraph B.4.2 provides guidance when comparing results using the two different solvents. 1.4 The constituents that may be considered to have basic characteristics include organic and inorganic bases, amino compounds, salts of weak acids (soaps), basic salts of polyacidic bases, and salts of heavy metals. Note (2): This test method is applicable to both fresh oils and used oils as described in Sections 13, 14 and 16, and in the Appendix A. 1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of the standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
