- Typical practice: 12 months. Many organizations use an annual interval for passive attenuators. Depending on usage severity, environment, quality system, and historical stability, intervals of 12–24 months are common. If introducing to a controlled process from the secondary market, calibrate upon receipt and then set the interval based on results and risk.
