Z-SCORES SUMMARY

Aggregates – October / November 2018 (82)

The proficiency program was conducted in October & November 2018 with participants throughout Australia. This summary provides the z-scores for the tests performed in this program and are ordered as shown below.

• AS 1141 11 Particle size distribution

• AS 1141 12 Material finer than 75 µm

• AS 1141 14 Particle shape by proportional calliper (2:1)

• AS 1141 15 Flakiness index

• AS 1141 20.1 Average Least Dimensions(ALD)

• AS 1141 6.1 Apparent particle density

• AS 1141 6.1 Particle density on a dry basis

• AS 1141 6.1 Particle density on a saturated–surface dry basis

• AS 1141 6.1 Water absorption

A z-score summary is provided to allow participants to gauge performance and address outliers as early as possible. It is recommended that any remedial action be undertaken cautiously until the final report for the program has been consulted. The z-scores shown are unlikely to change significantly. Small changes however may become necessary during preparation of the final report. The final report provides other information, apart from z-scores, that may be used to assess performance and interpret the significance of outliers. Participants may forward the summary report to NATA as an indication of a participant’s general performance. The final report once issued supersedes the z-score summary. All participants need to assess their overall performance once the final report has been issued. Please direct questions to:
