1、Designation: D6448 141D6448 16Standard Specification forIndustrial Burner Fuels from Used Lubricating Oils1This standard is issued under the fixed designation D6448; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of last
2、revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.1 NOTEEditorial changes to SI units formatting were made throughout in December 2014.1. Scope*1.1 This specification covers four grades
3、 of fuel oil made in whole or in part with hydrocarbon-based used or reprocessedlubricating oil or functional fluids, such as preservative and hydraulic fluids. The four grades of fuel are intended for use in varioustypes of fuel-oil-burning industrial equipment under various climatic and operating
4、conditions. These fuels are not intended for usein residential heaters, small commercial boilers, combustion engines, or marine applications,1.1.1 Grades RFO4, RFO5L, RFO5H, and RFO6 are used lubricating oil blends, with or without distillate or residual fuel oil,or both, of increasing viscosity and
5、 are intended for use in industrial burners equipped to handle these types of recycled fuels.NOTE 1For information on the significance of the terminology and test methods used in this specification, see Appendix X1.1.2 This specification is for use in contracts for the purchase of fuel oils derived
6、from used lubricating oil and for the guidanceof consumers of such fuels. This specification does not address the frequency with which any particular test must be run.1.3 Nothing in this specification shall preclude observance of national or local regulations, which can be more restrictive. Insome j
7、urisdictions, used oil is considered a hazardous waste and fuels from used oil are required to meet certain criteria beforeuse as a fuel.NOTE 2For United States federal requirements imposed on used oil generators, transporters and transfer facilities, reprocessors, marketers, andburners, see 40 CFR
8、279.NOTE 3The generation and dissipation of static electricity can create problems in the handling of distillate burner fuel oils. For more informationon the subject, see Guide D4865.1.4 The values stated in SI units are to be regarded as standard; non-SI units, when given, are for information only.

35、 coke ovens; or blast, smelting, melting, refining, or drying ovens.(b) industrial boilerslarge indirect heating units that transfer thermal energy to water or other fluids or gases for use inheating in industrial settings and in manufacturing processes3.3.2 reprocessing, n in petroleum product recy
36、cling, the preparation of used oil to be suitable as a fuel.3.3.2.1 DiscussionReprocessing includes procedures such as settling, filtration, blending, distillation, and chemical treatment.4. Classification4.1 There are four grades of industrial burner fuel containing recycled lubricating oils covere
37、d by this specification. Thesegrades may or may not correlate directly with similar grades in other ASTM standards. The RFO designation identifies them asReprocessed Fuel Oils. The usage descriptions of each grade may not describe all the uses, but are included as general information.The four grades
38、 are described as follows:4.1.1 Grade RFO4Primarily a blend of used lubricating oils and distillate or a reprocessed distillate product derived from usedoil. It is intended for use in pressure atomizing industrial burners with no preheating.This grade of recycled oil fuel is used in manymedium capac
39、ity industrial burners where ease of handling justifies the higher cost over the heavier used oil fuels.4.1.2 Grade RFO5LA straight (100 %) used lubricating oil blend or a used lubricating oil and distillate blend fuel ofintermediate viscosity, heavier than Grade RFO4. It is intended for use both in
40、 pressure-atomizing industrial burners not requiringhigher cost distillates and in burners equipped to atomize oils of higher viscosity with or without pre-heating. Its permissibleviscosity range allows it to be pumped and atomized at relatively low-storage temperatures.4.1.3 Grade RFO5HAstraight (1
41、00 %) used lubricating oil blend or a used lubricating oil and residual blend fuel, heavier thanGrade RFO5L. It is intended for use in industrial burners equipped with devices that atomize oil of higher viscosity than domesticburners can handle. Preheating may be necessary in some types of equipment
42、 for burning and in colder climates for handling.4.1.4 Grade RFO6Ahigh-viscosity used lubricating oil and residual blend fuel, heavier than Grade RFO5H. It is intended foruse in large industrial heaters and may require preheating in the storage tank to permit pumping.Additional preheating at the bur
43、nermay be necessary to permit satisfactory atomization. The extra equipment and maintenance required to handle this fuel usuallypreclude its use in small installations.5. General Requirements5.1 The fuel oils specified herein shall contain a minimum volume of 25 % of used lubricating oil-derived pro
44、ducts, the balancebeing a Specification D396 fuel oil or suitable refinery stocks.5.2 The fuel oils shall be homogeneous fluids consisting primarily of hydrocarbons. Fuel oils containing residual componentsshall remain uniform in storage and shall not separate by gravity or aging into layers in norm
45、al operating conditions.NOTE 4Prolonged storage or equipment down time may necessitate circulation of the fuel oil in-tank to prevent such separation.5.3 The fuel oil shall not contain excessive amounts of organic or inorganic acids, or both, and shall be free of solid or fibrousmatter that could ca
46、use system handling or maintenance problems. The buyer and seller should agree on any requirements forparticle size.NOTE 5The fuels defined by this specification are appropriate only for burners capable of handling and combusting fuels with potentially highermetals and ash content.D6448 1636.
