Purpose:

To introduce the concept of "calibration interval"

To obtain admissions as to the importance of calibration interval in the international scientific literature

To obtain an admission that neither the ATC/CFS nor the manufacturer mandate a calibration interval for approved instruments, though the manufacturer so specifies for ASDs

To introduce some international standards on reliability including ISO 17025

To introduce the concept of "uncertainty growth"

To connect "reliability", "calibration interval", and "uncertainty growth" "over time"
