1.1 This specification covers two grades of burner fuel consisting of triglycerides and naturally occurring constituents of triglycerides including monoglycerides, diglycerides, and free fatty acids and distinguished by the pour point. The grade designation (TBF) identifies them as triglyceride burner fuels.

1.2 The triglyceride burner fuels specified are intended for use in commercial or industrial air or steam-atomized fuel oil burning equipment manufactured from materials compatible with fuels having an acid number as specified in Table 1 and under various climatic and operating conditions for the purposes of heat generation. The fuels specified herein are not intended for blending with conventional fuel oils for this purpose. They are not intended for use in burners <0.32 GJ/h (0.3 × 106 BTU/h) such as residential burners or small pressure atomization burners nor are they intended for use in internal combustion engines or marine applications.

Note 1—For information on the significance of the terminology and test methods used in this specification, see Appendix X1.

1.3 This specification does not address the frequency with which any particular test shall be run.

1.4 Nothing in this specification shall preclude observance of national or local regulations, which can be more restrictive.

1.5 The text of this standard references notes and footnotes that provide explanatory material and shall not be considered as requirements of the standard. The table in this standard references footnotes, and these are to be considered as requirements of the standard.

1.6 The values given in SI units are to be regarded as the standard. The values given in parentheses are for information only.

1.7 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
