ASTM D7467 Standard Specification for Diesel Fuel Oil, Biodiesel Blend (B6 to B20)
4. Test Methods
4.1 The requirements enumerated in this specification shall be determined in accordance with the following methods:
4.1.1 Acid Number - Test Method D664.

4.1.2 Flash Point - Test Method D93, except where other methods are prescribed by law. Test Method D3828 may be used as an alternate with the same limits. Test Method D56 may be used as an alternate with the same limits, provided the flash point is below 93°C. This test method will give slightly lower values. In cases of dispute, Test Method D93 shall be used as the referee method.

4.1.3 Cloud Point - Test Method D2500. For all B6 to B20 grades in Table 1, Test Method D7397 and the automatic Test Methods D5771, D5772, or D5773 may be used as alternates with the same limits. Test Method D3117 may also be used since it is closely related to Test Method D2500. In case of dispute, Test Method D2500 shall be the referee test method.

4.1.4 Cold Filter Plugging Point (CFPP) - Test Method D6371.

4.1.5 Low Temperature Flow Test (LTFT) - Test Method D4539.

4.1.6 Water and Sediment - Test Method D2709.

4.1.7 Carbon Residue - Test Method D524.

4.1.8 Ash - Test Method D482.

4.1.9 Distillation - Test Method D86.

4.1.10 Viscosity - Test Method D445.

4.1.11 Sulfur - Table 2 shows the referee test methods and alternate test methods for sulfur, the range over which each test method applies and the corresponding fuel grades.

4.1.12 Aromaticity - Test Method D1319. This test method provides an indication of the aromatic content of fuels. For fuels with a maximum final boiling point of 315°C, this test method is a measurement of the aromatic content of the fuel. Grade S5000 does not have an aromatics content.

4.1.13 Cetane Index - Test Method D976.

4.1.14 Lubricity - Test Method D6079.

4.1.15 Copper Corrosion - Test Method D130, 3 h test at 50°C minimum.

4.1.16 Cetane Number - Test Method D613. Test Method D6890 may also be used. In cases of dispute, Test Method D613 shall be the referee test method.

4.1.17 Oxidation Stability - Test Method EN 15751. Test Method EN 14112 may also be used but has been shown to provide falsely low readings in some cases. See X1.16.2 for further information. In case of dispute, Test Method EN 15751 shall be the referee test method.

4.1.18 Biodiesel Content - Test Method D7371. Test Method EN 14078 may also be used. In cases of dispute, Test Method D7371 shall be the referee test method. See Practice E29 for guidance on significant digits.

5. Workmanship
5.1 The biodiesel blend (B6 to B20) shall be visually free of undissolved water, sediment, and suspended matter.

5.2 The biodiesel blend (B6 to B20) shall also be free of any adulterant or contaminant that may render the fuel unacceptable for its commonly used applications.

6. Requirements
6.1 The biodiesel blend (B6 to B20) specified shall conform to the detailed requirements shown in Table 1.

7. Keywords
7.1 biodiesel; biodiesel blend; diesel; fuel oil; petroleum and petroleum products
