    Revision of D5550 - 06 Standard Test Method for Specific Gravity of Soil Solids by Gas Pycnometer

    (What is a Work Item?)

    Active Standard: D5550 - 06

    Developed by Subcommittee: D18.03 | Committee D18 | Contact Staff Manager



    WK38039

    1. Rationale

    This Test Method carries a 2006 approval date, and is currently overdue. A recent ballot to reapprove the Test Method received two negative votes. The changes here have been made to address these negatives, and to bring the document up to date after introduction of larger capacity pycnometers. Several changes are proposed here. The first is editorial in nature, the removal of a comma in the first sentence of section 1.3.1 to improve clarity of the statement. The first technical change is removal of section 3.2 and Note 1 since it is not necessary to define specific gravity in this document. The second technical change, in paragraph 8, reflects new apparatus available to accommodate sample volumes up to 350 cm3. The final technical change appears in section 10.4, where pertinent information from Note 1 has been added. The Summary of Changes has been updated to reflect these changes. Track Changes has been utilized to facilitate location of the changes. Only these changes are being balloted at this time, as the remainder of the Test Method was acceptable to Committee D18 during the recent ballot to reapprove.
