A question without a single answer
One of the questions customers ask most frequently is:
“How often should a calibration artifact be recalibrated?”
The honest answer is that there is no universal schedule.
The correct interval depends on how the artifact is used.
Factors that influence recalibration intervals
Several factors should be considered:
- frequency of use
- environmental conditions
- handling practices
- required measurement uncertainty
- audit requirements
Artifacts used daily in production environments generally require more frequent verification than artifacts used occasionally in controlled laboratory conditions.
Signs that recalibration may be necessary
Experienced engineers often watch for warning signs such as:
- unusual measurement drift
- repeatability issues
- visible surface damage
- unexpected dimensional changes
Waiting for a scheduled calibration date may not always be sufficient.
Special considerations for CT systems
In industrial CT environments, artifacts are frequently exposed to long scanning cycles and changing operating conditions.
A Ruby Plate for CT System is often selected because of its excellent dimensional stability and wear resistance.
Even so, periodic verification remains important to ensure confidence in volumetric measurements.
Final thoughts
A calibration schedule should be based on risk rather than habit.
The goal is not simply maintaining a certificate.
The goal is maintaining confidence in measurement results.
