What is the purpose of the shaker adequacy check?

The purpose of the shaker adequacy check is to confirm proper shaker functionality. This is crucial in ensuring that the equipment used for sample preparation is working correctly and performing as intended. If a shaker is not functioning properly, it may not adequately separate materials based on size, leading to inaccurate test results and affecting the overall integrity of the aggregate analysis.

When conducting tests on aggregates, it's essential that the shaker operates within specific parameters to achieve consistent and reliable outcomes. Regular checks help identify any issues before they lead to problems in the testing process, thus ensuring that the quality of the work being performed is maintained.

Proper functionality includes verifying aspects such as the shaker's speed, motion, and the effectiveness of the sieving process, all of which play a vital role in achieving accurate particle size distribution. Therefore, confirming that the shaker is fit for use is a critical part of the quality control process in aggregate testing.
