ASTM WK37434

    Revision of D2885 - 10a Standard Test Method for Determination of Octane Number of Spark-Ignition Engine Fuels by On-Line Direct Comparison Technique

    (What is a Work Item?)

    Active Standard: D2885 - 13

    Developed by Subcommittee: D02.01 | Committee D02 | Contact Staff Manager


    1. Rationale

    There has been a request by the Gulf Coast Regional Group to replace the current wording in ASTM D2885 regarding the storage of standard fuel, with some proposed revised wording suggested by them. This matter was referred to D02.01 Section G (Editorial) to provide further assistance. The proposed revision addresses the concept that to maintain the knock characteristics of the standard fuel, it is preferred that bulk storage containers be kept in a cool area. However, it should be recognized that large volumes of standard fuel can be stored at higher temperatures while successfully maintaining the knock characteristics, if the bulk storage containers are protected from direct sun light. The proposed revision also addresses the concept that if the standard fuel in a bulk storage container is to be transferred into small containers (1 gal. or less), the bulk storage containers of standard fuel and smaller containers should be chilled to below 10C (50F) for storage, to maintain the knock characteristics of the standard fuel.
