ASTM WK32855

    Work Item: ASTM WK32855 - Revision of D95 - 05(2010) Standard Test Method for Water in Petroleum Products and Bituminous Materials by Distillation

    (What is a Work Item?)

    Active Standard: D95 - 13e1

    Developed by Subcommittee: D02.02.01 | Committee D02 | Contact Staff Manager

    1. Rationale

    It has been brought to the attention of the subcommittee that no commercial suppliers of the petroleum distillate solvent specified in 6.1.2 exist. As such, this causes labs not to be in compliance with the method requirements when testing samples that correspond to the prescriptive use of this solvent in Table 1. Since the functional requirement that needs to be met in the method is for labs to use a water-immiscible solvent-carrier liquid that is miscible in the material being tested, labs should have the option of choosing an appropriate solvent, as long as it meets this requirement. As an example, many labs that currently perform D95 also perform D4006 (which uses reagent grade xylene as the water immiscible solvent-carrier liquid for crude oils that are tested) and have demonstrated success in using the reagent grade xylene in D95 for the materials listed in Table 1 in place of the petroleum distillate solvent specified, due to the lack of commercially available suppliers as noted above. As such, a proposed revision is identified to define the functional requirements that need to be satisfied in 6.1, as well as providing recommendations (i.e., non-mandatory information) on solvent-carrier liquids to use for certain materials in Table 1, rather than making the information in Table 1 as prescriptive requirements as in the current standard. Secondly, because of the problems of identifying commercial suppliers of the petroleum distillate solvent specified in 6.1.2, a proposed revision is identified to allow labs to use solvents that meet the specification requirements in D235.
