Standard Test Method for
Determination of Total Sediment in Residual Fuels1

This standard is issued under the fixed designation D 4870; the number immediately following the designation indicates the year of
original adoption or, in the case of revision, the year of the last revision. A number in parentheses indicates the year of last reapproval. A
superscript epsilon (e) indicates an editorial change since the last revision or reapproval.

1. Scope*

1.1 This test method covers 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
the method can be used for the assessment of total sediment after
regimes of fuel pretreatment designed to accelerate the aging
process.

1.2 The values stated in acceptable SI units are to be
regarded as the standard.

1.3 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. For specific
warning statements, see 7.2, 7.3, Annex A1, and X1.6.1.
