Aggregate Tests

Aggregate tests can either be based on data collected at your plant or supplied by the quarry. Each aggregate can only have one quarry test. If new data is supplied by the quarry, edit the existing test.

Access this feature by selecting Quality Control menu > Aggregate Tests (see Figure 1 below).

Test Results

Click Start Test to begin. The only data entry fields on the Aggregate Test Results page are the Retained Weights. The test will fail if any of the weights fall outside the scale variance range (see Figure 5 below).

Figure 5

Scale Variance

Scale variance gives you a +/- range where a value within that range but outside of the spec will still pass. The variance applies to the Cumulative Passing Percent and Total Retained Weight (Figure 6).

Scale variance is set on a per plant basis. It's a plus/minus value that is not variable. IE, plus must equal minus. At this time, the scale variance has no data entry field. Contact Concrete Vision support for more details.

Figure 6

Here's another example of a test that passes with minor deviations acceptable within the scale variance range (see Figure 7 below).

Grading Chart

The results are graphed in a chart at the bottom of the page. Sieves that are marked "Excluded" are not shown in the chart (see Figure 8 bellow).
