3、.1. Scope*1.1 This test method covers the determination of sulfur inpetroleum products, including lubricating oils containing addi-tives, additive concentrates, and lubricating greases that cannotbe burned completely in a wick lamp. The test method isapplicable to any petroleum product sufficiently
4、low in vola-tility that it can be weighed accurately in an open sample boatand containing at least 0.1 % sulfur.NOTE 1This test method is not applicable to samples containingelements that give residues, other than barium sulfate, which are insolublein dilute hydrochloric acid and would interfere in
5、the precipitation step.These interfering elements include iron, aluminum, calcium, silicon, andlead which are sometimes present in greases, lube oil additives, or additiveoils. Other acid insoluble materials that interfere are silica, molybdenumdisulfide, asbestos, mica, and so forth. The test metho
6、d is not applicable toused oils containing wear metals, and lead or silicates from contamination.Samples that are excluded can be analyzed by Test Method D1552.1.2 The values stated in SI units are to be regarded asstandard. No other units of measurement are included in thisstandard.1.3 This standar
7、d does not purport to address all of thesafety concerns, if any, associated with its use. It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.2.

QUALITY CONTROLX1.1 Confirm the performance of the instrument or the testprocedure by analyzing a quality control (QC) sample.X1.2 Prior to monitoring the measurement process, the userof the tes
19、t method needs to determine the average value andcontrol limits of the QC sample (see Practice D6299 and MNL7).9X1.3 Record the QC results and analyze by control chartsor other statistically equivalent techniques to ascertain thestatistical control status of the total testing process (see PracticeD6
20、299 and MNL 7). Any out-of-control data should triggerinvestigation for root cause(s).X1.4 In the absence of explicit requirements given in thetest method, the frequency of QC testing is dependent on thecriticality of the quality being measured, the demonstratedstability of the testing process, and
21、customer requirements.Generally, a QC sample is analyzed each testing day withroutine samples. The QC frequency should be increased if alarge number of samples are routinely analyzed. However,when it is demonstrated that the testing is under statisticalcontrol, the QC testing frequency may be reduce
22、d. The QCsample precision should be checked against the ASTM methodprecision to ensure data quality.X1.5 It is recommended that, if possible, the type of QCsample that is regularly tested be representative of the materialroutinely analyzed. An ample supply of QC sample materialshould be available fo
23、r the intended period of use, and must behomogenous and stable under the anticipated storage condi-tions. See Practice D6299 and MNL 7 for further guidance onQC and control charting techniques.8IP Standards for Petroleum and Its Products, Part I, Appendix E. Availablefrom Energy Institute, 61 New Ca
