1、Designation: D 808 05An American National StandardStandard Test Method forChlorine in New and Used Petroleum Products (BombMethod)1This standard is issued under the fixed designation D 808; the number immediately following the designation indicates the year oforiginal adoption or, in the case of rev

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

3、 covers the determination of chlorine inlubricating oils and greases, including new and used lubricat-ing oils and greases containing additives, and in additiveconcentrates. Its range of applicability is 0.1 to 50 m% chlo-rine. The procedure assumes that compounds containing halo-gens other than chl

4、orine will not be present.1.2 The preferred units are mass percent. The values statedin SI units are to be regarded as the standard. The values givenin parentheses are for information only.1.3 This standard does not purport to address all of thesafety concerns, if any, associated with its use. It is

5、 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. Attention is calledto specific warning statements incorporated in the test method.2. Referenced Documents2.1 ASTM Standards:2

Summary of Test Method3.1 The sample is oxidized by combustion in a

7、bombcontaining oxygen under pressure. (WarningStrict adher-ence to all of the provisions prescribed hereinafter ensuresagainst explosive rupture of the bomb, or a blow-out, providedthe bomb is of proper design and construction and in goodmechanical condition. It is desirable, however, that the bombb

8、e enclosed in a shield of steel plate at least 13 mm (12 in.)thick, or equivalent protection be provided against unforesee-able contingencies.) The chlorine compounds thus liberated areabsorbed in a sodium carbonate solution and the amount ofchlorine present is determined gravimetrically by precipit

9、ationas silver chloride.4. Significance and Use4.1 This test method may be used to measure the level ofchlorine-containing compounds in petroleum products. Thisknowledge can be used to predict performance or handlingcharacteristics of the product in question.4.2 This test method can also serve as a

10、qualitative tool forthe presence or non-detection of chlorine in petroleum prod-ucts. In light of the efforts in the industry to prepare chlorinefree products, this test method would provide informationregarding the chlorine levels, if any, in such products.5. Apparatus5.1 Bomb, having a capacity of

11、 not less than 300 mL, soconstructed that it will not leak during the test, and thatquantitative recovery of the liquids from the bomb may bereadily achieved. The inner surface of the bomb may be madeof stainless steel or any other material that will not be affectedby the combustion process or produ

12、cts. Materials used in thebomb assembly, such as the head gasket and lead-wire insula-tion, shall be resistant to heat and chemical action, and shall notundergo any reaction that will affect the chlorine content of theliquid in the bomb.5.2 Sample Cup, platinum, 24 mm in outside diameter at thebotto

13、m, 27 mm in outside diameter at the top, 12 mm in heightoutside, and weighing 10 to 11 g.5.3 Firing Wire, platinum, No. 26 B chlorineAPPENDIX(Nonmandatory Information)X1. QUALITY CONTROLX1.1 Confirm the performance of the instrument or the testprocedure by analyzing a QC sample.X1.2 Prior to monitor

14、ing the measurement process, the userof the method needs to determine the average value and controllimits of the QC sample (see Practice D 6299 and MNL 7).5X1.3 Record the QC results and analyze by control chartsor other statistically equivalent techniques to ascertain thestatistical control status

15、of the total testing process (see PracticeD 6299 and MNL 7).5Any 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 demon

16、stratedstability of the testing process, and 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 statisticalco

17、ntrol, 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 materialroutinely analyzed. An ample suppl

18、y of QC sample materialshould be available for the intended period of use, and must behomogenous and stable under the anticipated storage condi-tions. See Practice D 6299 and MNL 75for further guidance onQC and Control Charting techniques.SUMMARY OF CHANGESSubcommittee D02.03 has identified the loca
