The test methods ASTM D4870, ISO 10307, IP 375 and IP 390 (proc. A) cover the determination of total sediment up to 0.40 % m/m for distillate fuel oils containing residual components and to 0.50 % m/m in residual fuel oils having a maximum viscosity of 55 cSt (mm²/s) at 100°C. Some fuels can exceed the maximum filtration time specified in this test method due to factors other than the presence of significant quantities of insoluble organic or inorganic material. This test method can be used for the assessment of total sediment after regimes of fuel pretreatment designed to accelerate the aging process.
The Total sediment test according to ISO 10307-1 and ISO 10307-2 is a mandatory test for marine fuels according to ISO 8217. Both the distillate marine fuels and residual marine fuels need to be tested for total sediment.
