ASTM D2069 Standard Specification for Marine Fuels
6. Test Methods
6.1 The requirements enumerated in this specification shall be determined in accordance with the following ASTM or equivalent ISO test methods:
6.1.1 Density - Test Method D1298 (or ISO 3675). For Table 2, Test Method D1298 (or ISO 3675) shall be used at a temperature between 50 and 60°C and the hydrometer readings obtained converted to 15°C using Table 53 (b) (53 (b)) using inch-pound units) referred to in Guide D1250 (or ISO 91-1).
6.1.2 Viscosity - Test Method D445 (or ISO 3104).
6.1.3 Flash Point - Test Method D93 (or ISO 2719).
6.1.4 Pour Point - Test Method D97 (or ISO 3016).
6.1.5 Cloud Point - Test Method D2500 (or ISO 3015).
6.1.6 Carbon Residue - Test Method D189 (or ISO 6615) for marine residual fuels and Test Method D524 (or ISO 4262) for marine distillate fuels. If Test Method D524 (or ISO 4262) is not available, Test Method D189 (or ISO 6615) shall be used and the limits for the marine distillate grades shall be as follows: DMX is 0.14 % mass, DMA is 0.14 % mass, DMB is 0.28 % mass and DMC is 3.0 % mass.
6.1.7 Ash - Test Method D482 (or ISO 6245).
6.1.8 Sediment - Test Method D473 (or ISO 3735).
6.1.9 Water - Test Method D95 (or ISO 3733).
6.1.10 Visual Inspection - Test Method D4176 (Procedure B).
6.1.11 Cetane Number - Test Method D613 (or ISO 5165).
6.1.12 Sulfur - Test Method D4294 (or ISO 8754).
6.1.13 Vanadium - DIN 51 790, Part 2.
