1、Designation: D 187 94 (Reapproved 2003)e1An American National StandardStandard Test Method forBurning Quality of Kerosine1This standard is issued under the fixed designation D 187; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, th

2、e 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.e1NOTEWarning notes were editorially m

3、oved into text in November 2003.1. Scope1.1 This test method covers the qualitative determination ofthe burning properties of kerosine to be used for illuminatingpurposes. (WarningCombustible. Vapor harmful.)NOTE 1The corresponding Institute of Petroleum (IP) test method isIP 10 which features a qua

4、ntitative evaluation of the wick-char-formingtendencies of the kerosine, whereas Test Method D 187 features aqualitative performance evaluation of the kerosine. Both test methodssubject the kerosine to somewhat more severe operating conditions thanwould be experienced in typical designated applicati

5、ons.1.2 This standard 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. Specific w

It is essential to ensure that theburner fits vertically into the oil reservoir and that the wick-guide has parallel sides and is centrally disposed in relation tothe slot in the dome of the burner. Any distortion of thewick-guide

11、or dome will hinder attainment of the prescribedflame shape and render subsequent qualitative ratings unreli-able.5.2 Wick,419-mm paraffin flat, super quality, containingapproximately 43 ends of three-ply yarn, woven double plainweave with stitching ends, one blue stripe on one face and onegreen str

20、1 Test RoomIt is desirable to dedicate a suitable roomfor the exclusive conduct of kerosine burning tests. However,kerosine burning tests can be conducted in any part of a roomthat is adequately ventilated and reasonably free of drafts.When necessary, the test lamp should be surrounded with asuitabl

21、e circular shield to protect from drafts. The circularshield is to be constructed of draft-proof material of about 600mm diameter and height.7.2.2 Lamp LocationPlace the test lamps at least 300 mmapart and 300 mm from any wall or other obstruction.7.2.3 Test TemperatureMaintain test room temperature

22、above 15C and allow the temperature of the kerosine toapproach equilibrium room temperature within at least 5C.8. Sampling8.1 The fundamental objective of sampling is to obtain asample for testing purposes that is truly representative of theentire quantity of a given bulk product tank, batch, shipme

23、nt,and so forth, at the time and place of sampling.8.2 Thus, the sampling procedures employed are to ensureinitial procurement of a representative sample and also pre-clude subsequent contamination or deterioration of the sampleduring handling prior to testing. To this end, kerosine samplesfor burni

24、ng quality testing are to be obtained and handled instrict accordance with Practices D 4057 and D 4177. Rigorouscompliance with stipulated provisions for precautions, care,and cleanliness during sample handling is an essential require-ment.NOTEAll dimensions shown are in millimetres. Except where ot

25、her-wise indicated, the tolerance for chimney dimensions is 61 mm.FIG. 1 Test LampFIG. 2 Sight GageD 187 94 (2003)e129. Preparation of Apparatus9.1 Drain the lamp reservoir completely of any previouskerosine sample (WarningCombustible. Vapor harmful),and rinse successively several times with a small

26、 portion of thekerosine sample to be tested.9.2 Clean the lamp burner thoroughly with ASTM precipi-tation naphtha solvent (WarningExtremely flammable.Harmful if inhaled: vapors may cause flash fire), removingcompletely any deposits from the wick-guide, air holes, andducts.9.3 Soak the new chimneys f

27、or 24 h in dilute HCl(WarningCauses burns. Vapor harmful) (approximately6 N), clean with a test tube brush, rinse thoroughly withdistilled water, and dry completely. Then subject the preparednew chimneys to at least three preliminary 16-h burningperiods. Clean chimneys with detergent and hot water,

28、rinsethoroughly with distilled water, and completely dry betweeneach preliminary burning period. New chimneys are satisfac-tory for use only if the last of the preliminary burning periodsresults in deposits essentially similar to those obtained whenburning the same kerosine for 16 h with seasoned ch

29、imneys.Continue preliminary 16-h burning periods and cleanings untilseasoned chimney performance is achieved.9.4 Place several wicks into an insulated Soxhlet extractionapparatus in such a manner as to prevent distortion and extractwith boiling water (WarningAvoid skin contact with ex-posed hot surf

30、aces by use of protective equipment) for 3 h fromthe end of the first siphoning cycle. Remove the wicks from theSoxhlet extraction apparatus, lay flat between sheets of filterpaper, and press gently to remove excess moisture. Extract thewick with Formula 3A denatured ethanol (WarningFlammable. Denat

31、uredcannot be made nontoxic) for3hinan uninsulated Soxhlet extraction apparatus, drain the ethanolas completely as possible from the Soxhlet extractor andcontinue the extraction with ASTM precipitation naphtha(WarningExtremely flammable. Harmful if inhaled. Vaporsmay cause flash fire) for 1 h.10. Pr

32、ocedure10.1 Dry the wick in an oven (WarningAvoid skincontact with exposed hot surfaces by use of protective equip-ment) at 105C for 1 h. While still hot, soak the wick in thesample and insert the wick into the wick guide. Rinse thereservoir several times with the sample. Filter the samplethrough a

33、coarse-textured filter paper, to remove suspendedmatter and pour 900 mL into the reservoir and assemble thelamp.10.2 Hinge back the dome and chimney, and trim the wickcarefully with sharp scissors to produce a smooth and sym-metrical flame of the standard dimensions shown in Fig. 3.10.3 Trim the wic

34、k as follows: With sharp scissors cut thewick level with the wick guide, raise the wick, and cut atriangular portion from each corner as illustrated in Fig. 4.Round off very slightly the sharp corners produced. Removeany ragged projections by slight beveling of the top edges asillustrated in Fig. 5.

35、 Be careful not to compress or squeeze thewick with the fingers. Trimming should produce a smooth,symmetrical flame, free of peaks or ears. Check this by lightingthe lamp from time to time and inspecting the flame during thetrimming operation.10.4 After the wick is trimmed to yield a flame of standa

36、rdshape and dimensions, allow the lamp to burn for 0.5 h,extinguish; and trim again, removing any uneven points andcharred fiber. Relight the lamp and again check the shape anddimensions of the flame. Extinguish the flame, allow thechimney to cool, wash it with hot water, and dry with a cleanlint-fr

37、ee cloth.10.5 After the wick has been trimmed and the chimneywashed, allow the lamp to burn for 0.5 h and readjust the flameto the standard dimensions. At the end of this period weigh thelamp, while burning, to the nearest1gonaplatform balance.Weigh again after 1 h. If the rate of sample consumption

38、 differsfrom 22 6 4 g/h, check the flame dimensions and wickcondition for further trimming. Normally, the measurement ofsample consumption is needed only as a check on standardburning conditions, since with the specified flame size andshape, the initial rate of sample consumption will always bewithi

39、n these limits.NOTEAll dimensions shown are in millimetres.FIG. 3 Standard Dimensions for Shape and Size of FlameNOTEAll dimensions shown are in millimetres.FIG. 4 Wick Trimming.

40、.6 Allow the sample to burn continuously without furtheradjustment of any kind for the duration of the test, which shallbe 16 h (or other specified period) of continuous burning afterthe first weighing. At the end of this period reweigh to thenearest 1 g and record any changes in height, width, or s

41、hapeof the flame to the nearest 1 mm.10.7 Examine the density and color of the chimney deposit.11. Report11.1 The report shall include the following:11.1.1 Average burning rate of the sample to the nearest1 g/h.11.1.2 Initial dimensions of the flame to the nearest 1 mm.11.1.3 Final dimensions of the

42、 flame to the nearest 1 mm.11.1.4 Density of the chimney deposit (none, light, medium,or heavy) and its color (none, white, yellow, or brown).12. Precision and Bias512.1 The precision of the test method as determined bystatistical examination of interlaboratory results is as follows:12.1.1 Repeatabi
