NETTCP Soils & Aggregate Inspector Practice Exam

In the shaker adequacy check, after one minute of testing, the pan weight is measured to assess whether the shaker is functioning correctly. This measurement is crucial as it allows inspectors to determine if the shaker's performance is adequate for effective particle size analysis. By weighing the pan, the inspector can validate the consistency and accuracy of the shaker's operation, ensuring that the test results for the soil or aggregate samples are reliable.

This step is fundamental in maintaining quality control in testing procedures, as the pan's weight will help indicate whether particles have been adequately separated and whether the shaker is operating within acceptable parameters. The pan weight serves as a key reference point for further analysis and adjustments, which may include recalibration of the shaker or repeating the test if necessary.
