Calibration of test weights

Calibrated measuring instruments require calibrated testing equipment.

For scales these are calibrated test weights, also known as "Normal".

Test weights must be recalibrated periodically depending on frequency of use. This will ensure that they can withstand the demands of a reliable functioning test equipment.

Recalibration times depend on the frequency of use, the conditions of use and your safety requirements.

The standard specifies no particular recalibration interval. We recommend to recalibrate your test weights with intensive use every 6 months and every 12 months with normal use.
