    Revision of D5236 - 18a Standard Test Method for Distillation of Heavy Hydrocarbon Mixtures (Vacuum Potstill Method)

    (What is a Work Item?)

    Active Standard: D5236 - 18a

    Developed by Subcommittee: D02.08 | Committee D02 | Contact Staff Manager

    It was brought to the subcommittees attention by method users that recent inquiries to chemical suppliers havent been successful in sourcing chemicals referenced in table A2.2 at purity specifications given in the test methods annex A2.2.3.2. Based on the text in this section of the method, this would require a purity of 99.9+% which is not commercially available in aliquots that are economically feasible. Also, based on industry experience, a purity of 99.0+% will meet the temperature requirements of this annex.
