A note on calibration dates:

Calibration dates are suggested by the manufacturer, but you may select a recalibration date with an interval of your choosing, as long as this is documented in your Quality Manual or other quality documents. Atema recommends a 5-year recalibration date for gauges used as a Master set. Atema certifies that all tools sold are new (never refurbished) and are stored in temperature and humidity-controlled storage.
