1、Designation: D808 11D808 16Standard Test Method forChlorine in New and Used Petroleum Products (HighPressure Decomposition Device Method)1This standard is issued under the fixed designation D808; the number immediately following the designation indicates the year oforiginal adoption or, in the case

2、of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.This standard has been approved for use by agencies of the U.S. Department of Defense.1. Scope*1.1 This t

3、est method covers the determination of chlorine in lubricating oils and greases, including new and used lubricatingoils and greases containing additives, and in additive concentrates. Its range of applicability is 0.10.1 m% to 50 m% chlorine. Theprocedure assumes that compounds containing halogens o

4、ther than chlorine will not be present.1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.1.2.1 The preferred units are mass percent.1.3 This standard does not purport to address all of the safety concerns, if any, associated

5、 with its use. It is the responsibilityof the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatorylimitations prior to use. Attention is called to specific warning statements incorporated in the test method.2. Referenced Documents2.

Thechlorine compounds thus liberated are absorbed in a sodium carbonate solution and the amount of chlorine present is determinedgravimetrically by precipitation as silver chloride.4. Significance and Use4.1 This

10、 test method may be used to measure the level of chlorine-containing compounds in petroleum products. Thisknowledge can be used to predict performance or handling characteristics of the product in question.4.2 This test method can also serve as a qualitative tool for the presence or non-detection of

11、 chlorine in petroleum products.In light of the efforts in the industry to prepare chlorine free products, this test method would provide information regarding thechlorine levels, if any, in such products.1 This test method is under the jurisdiction of ASTM Committee D02 on Petroleum Products Produc

QUALITY CONTROLX1.1 Confirm the performance of the instrument or the test procedure by analyzing a QC sample.X1.2 Prior to monitoring the measurement process, the user of the method needs to det

20、ermine the average value and control limitsof the QC sample (see Practice D6299 and MNL 7).5X1.3 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 Practice D6299 and MNL 7).5 A

21、ny 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 process, and customer requir

22、ements. Generally, a QCsample is analyzed each testing day with routine samples. The QC frequency should be increased if a large number of samples areroutinely analyzed. However, when it is demonstrated that the testing is under statistical control, the QC testing frequency maybe reduced. The QC sam

23、ple precision should be checked against the ASTM method precision to ensure data quality.X1.5 It is recommended that, if possible, the type of QC sample that is regularly tested be representative of the material routinelyanalyzed. An ample supply of QC sample material should be available for the int

24、ended period of use, and must be homogenousand stable under the anticipated storage conditions.
