What is a requirement for maintaining the accuracy of inspection tools?

Calibration frequency should be based on manufacturer recommendations because the manufacturer is typically the authority on how the tool is designed to operate optimally. They provide specific guidelines on how often calibration should be performed to ensure accuracy and reliability. This ensures that tools are functioning correctly and provides a quality assurance measure, as instruments can vary widely in their need for recalibration based on their design, use, and environmental factors. Following the manufacturer's recommendations helps maintain compliance with regulatory standards and promotes safety in inspections, ultimately ensuring that the results of any inspections conducted are dependable and valid.

Adhering to the manufacturer’s guidelines also aligns with best practices in various industries, guaranteeing that any tools used remain compliant with applicable laws and regulations. This attention to detail is crucial in maintaining the integrity of inspection practices, which can impact public safety and operational effectiveness.
