ASTM WK33635

    Work Item: ASTM WK33635 - Revision of D1401 - 10 Standard Test Method for Water Separability of Petroleum Oils and Synthetic Fluids

    (What is a Work Item?)

    Active Standard: D1401 - 12

    Developed by Subcommittee: D02.C0.02 | Committee D02 | Contact Staff Manager

    1. Rationale

    The scope for this proposed revision change includes to allow for the optional use of a dye to help differentiate the layers in D1401 testing. Colorless and dark fluids tested in D1401 can be difficult for the test operator to distinguish between the oil, water, and emulsion layers. An oil-soluble dye was found to help differentiate these layers without affecting the test results. 88 oils (44 pairs of dyed and undyed) were tested at 5 labs and the results were within the D1401-10 precision. The dyed samples helped the operator differentiate the layers without affecting results. This option was approved at D02.C0; but the committee decided to move this into an Appendix.
