Standard Test Method for Water and Sediment in Fuel Oils by the Centrifuge Method (Laboratory Procedure)

SCOPE
1.1 This test method covers the laboratory test for determination of water and sediment in fuel oils by using the centrifuge method in the range from 0 to 30% volume. This chapter, along with API Chapter 10.3 (Test Method D 4007, IP 359), supersedes the previous edition of ASTM Test Method D 1796 (API Standard D 2548, IP75).  
Note 1-With some types of fuel oils such as residual fuel oils or distillate fuel oils containing residual components, it is difficult to obtain water or sediment contents with this test method. When this situation is encountered, Method D 95 (API MPMS Chapter 10.5) or Test Method D 473 (API MPMS Chapter 10.1) may be used.
1.2 annex A2 contains a procedure for saturating toluene with water.  
1.3 the values stated in SI units are to be regarded as the standard. The values in parentheses are for information only.  
1.4 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 a specific precautionary statement see 5.1.
