How frequently should weights be calibrated?
• Initially weights are usually calibrated on an annual basis, dependant on material type and how they are handled and stored. Once a history of uncertainty has been established the calibration cycle can be varied. Your quality system will help you identify the calibration interval. The period is usually based on the time interval for a significant change in mass to occur or for the weight to move outside the appropriate tolerance.
