ASTM WK41796

    Revision of D421 - 85(2007) Standard Practice for Dry Preparation of Soil Samples for Particle-Size Analysis and Determination of Soil Constants

    (What is a Work Item?)

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


    1. Rationale

    This standard has a 2007 date and requires action be taken to prevent the standard from being dropped. Several items have been added to bring the standard into compliance with D18 required caveats and sections. Sections related to specimen preparaton for soil constants have been removed because these prepartion tasks are covered in each of the indiviual standards. The Title has been revised to reflect this change as well. Grammatical revisions have been incorporated to clarify several phrases. We look forward to input regarding the proposed revisions from the D18 committee members
