The sand being used for this test must be 'calibrated.' This confirmation of the sand’s bulk density must be accomplished ________________________.
Understand the Problem
The question asks about the frequency at which the calibration of sand's bulk density must be confirmed according to specified criteria in a testing protocol.
Answer
Daily by the Technician prior to conducting in-place density tests.
The final answer is 'daily' by the Technician prior to conducting in-place density tests.
Answer for screen readers
The final answer is 'daily' by the Technician prior to conducting in-place density tests.
More Information
The calibration of the sand's bulk density is crucial for accurate in-place density tests. It ensures consistency and reliability in measurements.
Tips
A common mistake is neglecting daily calibration, which can lead to inaccurate test results.
