ASTM D6448-04 PDF

1.1 This specification covers four grades of fuel oil made in whole or in part with hydrocarbon-based used or reprocessed lubricating oil or functional fluids, such as preservative and hydraulic fluids. The four grades of fuel are intended for use in various types of fuel-oil burning industrial equipment under various climatic and operating conditions. These fuels are not intended for use in residential heaters, small commercial boilers, or combustion engines.

1.2 Grades RF04, RF05L, RF05H, and RF06 are used lubricating oil blends, with or without distillate or residual fuel oil, or both, of increasing viscosity and are intended for use in industrial burners equipped to handle these types of recycled fuels.

Note 1- For 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 from used lubricating oil and for the guidance of consumers of such fuels. This specification does not address the frequency with which any particular test must run.

1.3 Nothing in this specification shall preclude observance of national or local regulations, which can be more restrictive. In some jurisdictions, used oil is considered a hazardous waste and fuels from used oil are required to meet certain criteria before use as a fuel.

Note 2- For United States federal requirements imposed on used oil generators, transporters and transfer facilities, reprocessors, marketers, and burners, see 40 CFR 279.

Note 3- The generation and dissipation of static electricity can create problems in the handling of distillate burner fuel oils. For more information on the subject, see Guide D 4865.

1.4 The values stated in SI units are to be regarded as the standard; non-SI units, when given, are for information only.
