What requirement must be met by firmware in devices undergoing testing or calibration?

Firmware in devices undergoing testing or calibration must meet the same validation requirements as software because firmware operates in a similar manner to software and is integral to the device’s functionality. Validation ensures that the firmware performs as intended and complies with applicable standards and regulations. This is particularly important in calibration work, where accuracy and reliability are critical to ensuring that measurements are correct and that devices function as expected. Meeting the same validation requirements helps to guarantee that both the hardware and firmware are properly tested, minimizing the risk of errors during calibration and ensuring consistent performance across different devices and scenarios.
