8、upersessionThis part of BS 2000 supersedes BS 2000-10:1995, which is withdrawn.Information about this documentThis new edition has been updated to be in line with changes implemented bythe Energy Institute.BS 2000 comprises a series of test methods for petroleum and its products thatare published by

9、 the Institute of Petroleum (IP) and have been accorded thestatus of a British Standard. Each method should be read in conjunction with thepreliminary pages of “Standard Methods for Analysis and Testing of PetroleumProducts and British Standard 2000 Parts” which gives details of the BSI/IPagreement

20、.1 charthe blackened carbonized portion of the wick remaining when kerosine isburned under specified conditions4 PrincipleA sample of kerosine is burned in a test lamp, under specified conditions, for 24h. At the end of this period, the mass of kerosine burned and the mass of charformed on the wick

21、are measured. Provision is made for the reporting of aqualitative assessment of the appearance of the glass chimney on thecompletion of the test.5 Reagents5.1 Use only reagents of recognized analytical grade and water conforming tothe requirements of grade 3 of BS EN ISO 3696:1995.5.2 Denatured etha
