How Often Should I have my weights calibrated? Why? Are there any regulation and/or standard pertaining to calibration intervals?
It is recommended that if you use your weights infrequently to moderately, you should have them recalibrated once a year. However, if your weights are used very frequently or several times a day, then you should have them calibrated once every six months. Although there are no standards or regulations that specifically address recalibration intervals, this is the industry norm in order to ensure that these standards are still within their specified tolerances. It is not unusual to see significant “as found” failure rates on those weights that are not recalibrated on an annual basis.
