As many of you may already know, the American Society for Testing and Materials (ASTM) publishes standards for everything from Eye Protectors for Field Hockey (F2713-09) to the test method for kinematic viscosity of transparent and opaque liquids (and calculation of dynamic viscosity) (D445-06). One of the many various ASTM standards that I work with is the Standard Practice for Description and Identification of Soils (Visual-Manual Procedure) (D2488-09a). This method includes the Unified Soil Classification System (USCS) classification system for soils and expands upon it for the purposes of Environmental Assessment and Risk Management.
ASTM has released a new version of the D-2488 Standard Practice for Description and Identification of Soils (Visual-Manual Procedure). This is to replace the previous versions, D-2488-06 and D-2488-00; originally published as D-2488-66 T. I will be evaluating this standard over the next couple of weeks and will post my thoughts on it at that time.
