Significance and Use4.1 Representative samples of petroleum and petroleumproducts are requir

18、ed for the determination of chemical andphysical properties used to establish standard volumes, prices,and compliance with commercial and regulatory specifications.The treatment of samples from the time of collection until theyare analyzed requires care and effort to maintain their compo-sitional in

19、tegrity.5. Safety and Health Precautions5.1 In view of the potential health and safety hazardsassociated with the handling and mixing of petroleum samples,only qualified personnel should be involved.5.2 All sample handling and mixing equipment should beapproved by the parties involved. All equipment

20、 should beinstalled, operated, and maintained in a manner to minimizepotential health and safety hazards.6. Sample Containers6.1 No single container type will meet requirements of allpetroleum sampling operations. The following are generaldesign and construction considerations for sample containers.

21、6.2 Container Configuration:6.2.1 Containers should drain continuously toward the out-let to ensure complete liquid withdrawal.6.2.2 Cylindrical containers are better suited for samplesthat are to be tested for free water or sediment and water.6.2.3 Containers should not have internal pockets or dea

22、dspots.6.2.4 Internal surfaces of containers should minimize cor-rosion, incrustation, water, and sediment clingage.6.2.5 Container configuration should allow for the transferof samples from one container to another or to the analyticalapparatus while maintaining the integrity of the samplescomposit

23、ion.6.2.6 Containers should have an inspection cover/closure/cap of sufficient size to facilitate filling, inspection, andcleaning. A means of installing security seals should beprovided.6.2.7 Containers should allow for the preparation of ahomogeneous mixture of the sample while preventing the loss

24、of any constituents which affect the representativeness of thesample and the accuracy of the analytical tests.6.2.8 Containers should be made so as to avoid contamina-tion from external water or other foreign material.6.2.9 Containers used with closed loop mixers may beequipped with a discharge line

25、 inside the container which hasmultiple outlet ports.Another method of achieving the effect ofmultiple discharge ports is to split the discharge stream comingfrom the mixing pump into two or more separate streams witheach having its own inlet into the sample container.6.2.10 Containers used with clo

26、sed loop mixers should beequipped with a pressure/vacuum relief valve set so as not toexceed the design pressure of the container. A pressure gageshould also be provided.6.2.11 Containers used with closed loop mixers may havemultiple suction ports. As a minimum there should be onesuction port at the

27、 lowest point in the container.6.3 Container Size:6.3.1 A general rule is that both primary and intermediatecontainers should be large enough to hold the required samplesize within 80 % of the total capacity to facilitate mixing andto provide for thermal expansion.6.3.2 The size of primary container

28、s is determined from thesampling operation as described in Practices D 4057 (APIMPMS Chapter 8.1) and D 4177 (API MPMS Chapter 8.2).6.3.3 The size of intermediate containers should be as largeas practical to minimize surface tension effects with dueconsideration given to storage space requirements,

29、shippingrules and regulations, costs, availability, and other practicalconsiderations.6.4 Container Material:6.4.1 Sample containers are normally made of glass, metal,or plastic. Exercise care in the selection of container materialas it could affect the test results obtained from the sample.Containe

30、rs acceptable for samples to be tested immediatelymay not be acceptable for storage of sample.6.4.2 Glass containers are suitable for many sample test andstorage requirements. Clear glass bottles may be examinedvisually for cleanliness and allow for visual inspection of thesample for free water or s

31、olid impurities. Some petroleumsamples are affected by exposure to sunlight if clear glass isused. In these cases, brown glass bottles may afford thenecessary protection.6.4.3 Cans coated with tin must have seams that have beensoldered on the exterior surfaces with a flux of rosin cleaned ina suitab

32、le solvent. Such a flux is easily removed with gasoline,whereas many others are very difficult to remove. Minutetraces of flux may contaminate the sample so that resultsobtained on tests such as dielectric strength, oxidation resis-tance, and sludge formation may be erroneous. Exercise carealso to e

33、nsure that samples containing free or entrained waterare not corrosive to the metal. Internally epoxy-lined tin cansmay have residual contamination and precaution should betaken to ensure its removal.6.4.4 Cans made of stainless steel with welded seams aresuitable for many sampling operations. Other

34、 than ensuring thecleanliness, use of these containers presents no unusual con-cerns.6.4.5 Plastic bottles must be of a material that is imperviousto attack from the sample. This is especially a considerationwhen using plastic for long term storage of certain petroleumproducts. Clear plastic bottles

35、 are unsuitable for samplessensitive to light.D 5854 96 (2005)26.4.6 When sampling aviation fuels, Practice D 4306 shouldbe consulted for guidance on container selection. This practicegives information on the types of containers that have beenfound satisfactory for tests to determine water separatio

36、n,copper corrosion, electrical conductivity, thermal stability,lubricity, and trace metal content.6.4.7 Appendix X1 is a guide for selecting the material ofwhich sample containers may be made. It is impossible tocover all petroleum sampling container requirements; there-fore, when questions arise as

37、 to a containers suitability for agiven application, experience and testing should be reliedupon.6.5 Container Closures:6.5.1 For glass bottles, stoppers or screw caps made of amaterial that will not deteriorate or contaminate the samplemay be used. Care must be used when using cork stoppers.Situati

38、ons where corks should not be used include liquidswhere loss of light ends may affect the tests results and liquidswhich are hydroscopic or which have a low water contentspecification. Rubber stoppers should never be used.6.5.2 Cans and plastic bottles should be closed with screwcaps made of the sam

39、e material as the container. Caps shouldprovide a vapor tight seal.6.5.3 Screw caps for cans used to store or transport samplesmust be protected by a disk faced with a material that will notdeteriorate or contaminate the sample. Consideration of closuretype is important for samples where vapor loss

40、will affect thetest results.6.6 Federal Container RequirementsIn addition to therequirements listed above, any sample container that containshazardous materials or the residue of hazardous materialoffered for shipment or transportation by air, public roadway,rail, or water, or any combination thereo

41、f, must meet therequirements set forth in applicable regulations such as DOTregulations in the Code of Federal Regulations, Title 49,Section 173.6.7 Container Cleanliness:6.7.1 Sample containers must be clean and free from allsubstances which might contaminate the material beingsampled (such as wate

42、r, dirt, lint, washing compounds, naphthaand other solvents, soldering fluxes, acids, rust, and oil). Priorto further use, reusable containers such as cans and bottlesshould be rinsed with a suitable solvent. Use of sludge solventsto remove all traces of sediments and sludge may be necessary.Followi

43、ng the solvent wash, the container should be washedwith a strong soap solution, rinsed thoroughly with tap water,and given a final rinse using distilled water. Dry the containereither by passing a current of clean warm air through thecontainer or by placing it in a hot dust-free cabinet at 40C(104F)

44、 or higher. When dry, stopper or cap the containerimmediately. Normally, it is not necessary to wash newcontainers.6.7.2 Depending on service, receivers used in conjunctionwith automatic samplers may need to be washed with solventbetween uses. In most applications, it is not desirable orpractical to

45、 wash these receivers using soap and water asoutlined above for cans and bottles. The cleanliness andintegrity of all sample containers/receivers must be verifiedprior to use.6.7.3 When sampling aviation fuel, Practice D 4306 shouldbe consulted for recommended cleaning procedures for con-tainers tha

46、t are to be used in tests for determination of waterseparation, copper corrosion, electrical conductivity, thermalstability, lubricity, and trace metal content.6.8 Labels:6.8.1 Each sample container is to have a label attached to itwhich meets the requirements of the parties involved.6.8.2 Fig. 1 is

47、 an example of a label which shows the typicalinformation needed to properly identify the sample. In additionto this basic information, certain governmental agencies suchas DOT and OSHAhave additional labeling requirements withwhich personnel involved in the handling and shipping ofsamples must be f

48、amiliar.6.9 Shipping EnclosuresMany sample containers requirespecial shipping enclosures before they can be transportedfrom the point of collection. Regulations covering the transportof samples should be consulted (see the Code of FederalRegulations, Title 49, Section 173).6.10 Storage and Disposal:

49、6.10.1 Except when being transferred, samples should bemaintained in a closed container in order to prevent loss oflight components. Samples should be protected during storageto prevent weathering or degradation from light, heat, or otherpotential detrimental conditions.FIG. 1 Typical Sample LabelD 5854 96 (2005)36.10.2 There are many governmental agencies and jurisdic-tions that have regulations governing the storage and disposalof petroleum samples and containers that can be classified ashazardous materials or hazardous wastes.
