Validating the calibration and maturity curve regularly is important as there might be small variations in materials, batching equipment, and conditions which might affect the accuracy.

To validate your maturity calibration, make some samples during the next batch and compare the strength estimated using the Maturity Method with the strength obtained from other testing methods.

ASTM C1074 strongly recommends not to perform critical operations without verification of the maturity calibration or without strength validation using other test methods.
