How often must tools that require calibration be calibrated?

Tools that require calibration must be calibrated as specified by the manufacturer's recommendations or more frequently if needed to ensure accuracy and reliability. Calibration is critical for maintaining the precision of tools used in inspections, as incorrect measurements can lead to serious safety issues or compliance failures.

Manufacturers typically provide specific guidelines based on the tool's design, intended use, and the environment in which it operates. In some cases, frequent calibration may be necessary due to the tool's use frequency, the environment affecting the tool, or regulatory requirements. By adhering to the manufacturer's guidelines or opting for more frequent calibration, users can ensure that tools remain accurate and effective over time, thus maintaining safety and compliance with inspection standards.
