This SAE Aerospace Recommended Practice (ARP) addresses the general procedure for the best practices for minimizing uncertainty when calibrating thermal conductivity and cold cathode vacuum gauges, which includes the vacuum sensor(s) and accompanying electronics necessary for a pressure measurement to be made. It also includes the best practices for an in-process verification where limitations make it impossible to follow the best practices for minimizing uncertainty. Verifying the accuracy and operation of vacuum gauges is critical to ensure the maintenance of processes while under vacuum. ARP7449, Vacuum Gauge Calibration, was written to provide a best practice method for the calibration and testing of vacuum measuring systems for thermal processing equipment. Prior to this ARP, there was no guidance to follow. Aerospace standards such as AMS2769 and subscribing aerospace primes require vacuum system calibration to manufacturers recommendations, but many of these recommendations lacked detail instructions on the method of calibration.
