Installable Particle Classifications for GrainSize/CLSuite4/LabSuite4

NOTE: These files are provided "as-is" with no warranty as to their accuracy. It is the user's responsibility to verify that the selected classification system conforms to the latest standards.

Version 4.x of the GEOSYSTEM GrainSize, CLSuite4 and LabSuite4 programs support the addition of new particle size classification systems to the programs' default list. (A particle size classification system is a means of dividing up a tested soil into, e.g., gravel, sand, silt and clay, by specifying the maximum and minimum particle diameter of each for reporting purposes. For more information, see Section 3.1 in the GrainSize, CLSuite4 or LabSuite4 User's Guide.) The list below provides download links for specialized classification systems from various state Departments of Transportation and other organizations.

To install one of these classification systems, begin by installing the latest GrainSize/CLSuite4/LabSuite4 update from this link (note: this step is mandatory -- do not continue before updating your system). Next, right-click on the link provided, select "Save Target As" then save the file your program's shareable config. file directory (click this link for help in finding the proper directory).

Finally, restart your GEOSYSTEM program.

After you've installed your system, create or open a grain size test, select "Window" > "Sample Info.", then drop down the "Classification system" box to find your new particle classification.
