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 triglyceride burner fuels, Grade TBF5 and Grade TBF6, are intended for use in commercial or industrial air or steam-atomized fuel oil burning equipment manufactured under various climatic and operating conditions for the purposes of heat generation. This specification describes the properties and limits for triglyceride burner fuels to provide acceptable performance in liquid fuel burning equipment. It also addresses significance and use, sample collection and handling, and properties that are those of greatest significance in obtaining acceptable performance of the burner. The requirements enumerated in this specification shall be determined in accordance with the following ASTM test methods except as noted: pour point (Test Method D97), flash point (Test Method D93, Procedure B, except when other methods may be prescribed by law), water and sediment (Test Method D1796), viscosity (Test Method D445), density (Test Methods D1298, D4052, D5355, or D7042), titer (Test Method D1982), acid number (Test Method D664), ash (Test Method D482), sulfur (Test Method D4294), insolubles (Grade TBF5 and Grade TBF6) (Test Method D128, Section 12, Method 1), and heating value (heat of combustion) (Test Method D240).
This abstract is a brief summary of the referenced standard. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.
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.
