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

12、gravimetrically as barium sulfate.3.2 (WarningStrict adherence to all of the provisionsprescribed hereafter ensures against explosive rupture of thehigh pressure decomposition device, or a blow-out, providedthe high pressure decomposition device is of proper design andconstruction and in good mechan

The inner surface of the high pressuredecomposition device may be made of stainless steel or anyother material tha

20、t will not be affected by the combustionprocess or products. Materials used in the high pressuredecomposition device assembly, such as the head gasket andlead-wire insulation, shall be resistant to heat and chemicalaction, and shall not undergo any reaction that will affect thesulfur content of the

21、liquid in the high pressure decompositiondevice.NOTE 2Criteria for judging the acceptability of new and used oxygencombustion high pressure decomposition devices are described in PracticeE144.4.2 Oxygen Charging EquipmentThe valves, gauges, fill-ing tube, and fittings used in the oxygen charging sys

Thecharging equipment shall include either a pressure reducingvalve which will limit the discharge pressure to a maximum of4055 kPa or

24、a relief valve set to discharge at 4055 kPa in casethe pressure vessel should accidentally be overcharged. Meansshall also be provided for releasing the residual pressure in thefilling tube after the pressure valve has been closed.4.3 Sample Cup, platinum, 24 mm in outside diameter at thebottom, 27

QUALITY CONTROLX1.1 Confirm the performance of the instrument or the testprocedure by analyzing a quality control (QC) sample.X1.2 Prior

26、 to monitoring the measurement process, the userof the test method needs to determine the average value andcontrol limits of the QC sample (see Practice D6299 and MNL7).10X1.3 Record the QC results and analyze by control charts orother statistically equivalent techniques to ascertain the statis-tica

27、l control status of the total testing process (see PracticeD6299 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 mea

The QC frequency should be increased if alarge number of samples are routinely analyzed. However,when it is demonstrate

31、d that the testing is under statisticalcontrol, the QC testing frequency may be reduced. 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 m

32、aterialroutinely analyzed. An ample supply of QC sample materialshould be available for the intended period of use, and must behomogenous and stable under the anticipated storage condi-tions.
