1、Designation: D 187 08An 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, the year of last revis
2、ion. 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 Department of Defense.1. Scope*1.1 This test method covers the qualitative determ
3、ination ofthe burning properties of kerosine to be used for illuminatingpurposes. (WarningCombustible. Vapor harmful.)NOTE 1The corresponding Energy Institute (IP) test method is IP 10which features a quantitative evaluation of the wick-char-forming tenden-cies of the kerosine, whereas Test Method D
4、 187 features a qualitativeperformance evaluation of the kerosine. Both test methods subject thekerosine to somewhat more severe operating conditions than would beexperienced in typical designated applications.1.2 The values stated in SI units are to be regarded asstandard. No other units of measure
5、ment are included in thisstandard.1.3 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 limita
6、tions prior to use. Specific warningstatements appear throughout the test method.2.

8、3683. Summary of Test Method3.1 The kerosine sample is burned for 16 h in a specifiedlamp under specified conditions. The average rate of burning,the change in the shape of the flame, and the density and colorof the chimney deposit are reported.4. Significance and Use4.1 Since the information provid
9、ed by this test method islargely qualitative in nature, specific limits covering thefollowing characteristics are required in referring to this testmethod in specifications for kerosine:4.1.1 Duration of the test: 16 h is understood, if nototherwise specified;4.1.2 Permissible change in flame shape
10、and dimensionsduring the test;4.1.3 Description of the acceptable appearance of the chim-ney deposit.5. Apparatus5.1 Lamp Assembly,5conforming essentially to the shapeand dimensions shown in Fig. 1. It is essential to ensure that theburner fits vertically into the oil reservoir and that the wick-gui
11、de has parallel sides and is centrally disposed in relation tothe slot in the dome of the burner. Any distortion of thewick-guide or dome will hinder attainment of the prescribedflame shape and render subsequent qualitative ratings unreli-able.5.2 Wick,519-mm paraffin flat, super quality, containing

Vapors may cause flash fire.)7.2 Technical Precautions:7.2.1 Test RoomIt is desirable to dedicate a suita
21、ble 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 asuitable circular shield to protect from drafts. The
22、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 temperatureabove 15C and allow the temperature of the ker
23、osine 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, shipment,and so forth, at the time and place of samp
24、ling.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 burning quality testing are to be obtained and hand
25、led inNOTEAll dimensions shown are in millimetres. Except where other-wise indicated, the tolerance for chimney dimensions is 61 mm.FIG. 1 Test LampFIG. 2 Sight GageD187082strict accordance with Practices D 4057 and D 4177. Rigorouscompliance with stipulated provisions for precautions, care,and clea
26、nliness during sample handling is an essential require-ment.9. Preparation of Apparatus9.1 Drain the lamp reservoir completely of any previouskerosine sample (WarningCombustible. Vapor harmful),and rinse successively several times with a small portion of thekerosine sample to be tested.9.2 Clean the
27、 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 for 24 h in dilute HCl(WarningCauses burns. Vapor harmful)
28、 (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, rinsethoroughly with distilled water, and completely dry
29、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 chimneys.Continue preliminary 16-h burning periods and clea
30、nings 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 surfaces by use of protective equipment) for 3 h fromthe end
31、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. Denaturedcannot be made nontoxic) for 3 h inan uninsulated Sox
32、hlet 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. Procedure10.1 Dry the wick in an oven (WarningAvoid skin
33、contact 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 coarse-textured filter paper, to remove suspendedmatte
34、r 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 wick as follows: With sharp scissors cut thewick level wi
35、th 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. Be careful not to compress or squeeze thewick with th
36、e 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 standardshape and dimensions, allow the lamp to burn for 0.5
37、 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-free cloth.10.5 After the wick has been trimmed and the
38、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 nearest 1 g on a platform balance.Weigh again after 1 h. If the rate of sample consumption differsfrom 22 6 4 g/h, check the flame dimensio
39、ns and wickcondition for further trimming. Normally, the measurement ofsample consumption is needed only as a check on standardNOTEAll dimensions shown are in millimetres.FIG. 3 Standard Dimensions for Shape and Size of FlameNOTEAll dimensions shown are in millimetres.FIG. 4 Wick Trimming.

41、stment 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 shapeof the flame to the nearest 1 mm.10.7 Examine the densit
