Determination of Calibration Factor of Rebound Hammer as per IS 516 (Part 5/Sec 4) : 2020

In this video, you'll learn the Determination of the Calibration Factor of a Rebound Hammer as per IS 516 (Part 5/Sec 4): 2020. Calibration is an essential step before carrying out the rebound hammer test to ensure the instrument provides accurate and reliable rebound numbers for evaluating hardened concrete. The video explains the purpose of calibration, use of the standard steel anvil, calibration procedure, acceptance criteria, calculation of the calibration factor, and important precautions with a practical laboratory demonstration. IS 516 (Part 5/Sec 4):2020 requires the rebound hammer to be checked against a standard testing anvil before use to verify proper functioning.
