3、 Defense.1. Scope*1.1 This test method covers the determination of sulfur in petroleum products, including lubricating oils containing additives,additive concentrates, and lubricating greases that cannot be burned completely in a wick lamp. The test method is applicable toany petroleum product suffi

4、ciently low in volatility that it can be weighed accurately in an open sample boat and containing at least0.1 % sulfur.NOTE 1This test method is not applicable to samples containing elements that give residues, other than barium sulfate, which are insoluble in dilutehydrochloric acid and would inter

5、fere in the precipitation step. These interfering elements include iron, aluminum, calcium, silicon, and lead which aresometimes present in greases, lube oil additives, or additive oils. Other acid insoluble materials that interfere are silica, molybdenum disulfide, asbestos,mica, and so forth. The

6、test method is not applicable to used oils containing wear metals, and lead or silicates from contamination. Samples that areexcluded can be analyzed by Test Method D1552.1.2 This test method is applicable to samples with the sulfur in the range 0.09 to 5.5 mass %.1.3 The values stated in SI units a

Summary of Test Method3.1 The sample is oxidized by combustion in a high pressure decomposition device containing oxygen under pressure. Thesulfur, as sulfate in the high

10、 pressure decomposition device washings, is determined gravimetrically as barium sulfate.3.2 (WarningStrict adherence to all of the provisions prescribed hereafter ensures against explosive rupture of the highpressure decomposition device, or a blow-out, provided the high pressure decomposition devi

QUALITY CONTROLX1.1 Confirm the performance of the instrument or the test procedure by analyzing a quality control (QC) sample.X1.2 Prior to monitoring the measurement process, the user of the t

25、est method needs to determine the average value and controllimits of the QC sample (see Practice D6299 and MNL 7).9X1.3 Record the QC results and analyze by control charts or other statistically equivalent techniques to ascertain the statisticalcontrol status of the total testing process (see Practi

26、ce D6299 and MNL 7). Any out-of-control data should trigger investigationfor root cause(s).X1.4 In the absence of explicit requirements given in the test method, the frequency of QC testing is dependent on the criticalityof the quality being measured, the demonstrated stability of the testing proces

27、s, and customer requirements. Generally, a QCsample is analyzed each testing day with routine samples. The QC frequency should be increased if a large number of samples are8 IP Standards for Petroleum and Its Products, Part I, Appendix E. Available from Energy Institute, 61 New Cavendish St., London

An ample supply of QC sample material should be available for the intende
