Testwork: Laboratory Listing

Jump to: navigation, search

Laboratory listing

The laboratory where a test was conducted can be recorded with each sample. This is generally used for quality-control duplicate purposes in large testwork programs. The list is pre-populated with a number of laboratories whose results have been used in model calibration during the development of SAGMILLING.COM. The listing of labs is accessible via the "+" button at the top of every set of testwork. This "+" button option "Show lab listing" brings up the list.

The listing can be modified the same as any testwork value. Clicking the "id" button will allow a row to be edited, and new entries can be added using the "Enter New Result" link at the bottom of the list.

Database Fields

  • shortname is the short version of the laboratory name that appears in the Lab_id field when entering testwork.
  • longname is the optional long (formal) version of the laboratory name.
  • address and location are optional fields that store the physical address where the laboratory is located. Generally address is the street address and location is the city and country.
  • contact_name is an optional field where the name of the contact person at the laboratory may be entered.
  • color is the color this laboratory's results will appear on a parameter-versus-parameter plot.
  • shape is the shape of a data point that this laboratory's results will show as on a parameter-versus-parameter plot.
  • comment is an optional field that, for pre-loaded laboratories contains the list of grindability tests that the laboratory performs.

The optional fields are not required for the models to run and may be left blank, if desired. The shortname field is required to populate the Lab_id field in the other testwork tables (such as the ball mill work index page).

Comments on graphing

The color and shape are used in the graphing of a parameter-versus-parameter plot. In such a plot, the color and shape correspond to the test shown on the "X-axis". For example, if a rod mill work index was performed at a first laboratory and the drop weight test was performed at a second laboratory, the colors and shapes would work as follows:

  • WiRM on the X-axis, Axb on the Y-axis: the data point would use the first laboratory's color and shape.
  • Axb on the X-axis, WiRM on the Y-axis: the data point would use the second laboratory's color and shape.
