Class designation indicates the uncertainty or adjustment tolerances for reference weights. Balances, weight scales, force instruments, forces sensors, load cells, and weight modules should be calibrated using a reference weight or mass standard with a class tolerance greater than the readability or resolution of the sensor or instrument.
For calibration of an instrument with a resolution or readability to 0.001 grams, a reference weight near the maximum capacity of the scale or balance having a class tolerance of 0.0009 or smaller should be selected. Selection of a class tolerance of one-third or less of the scale’s readability will avoid the requirement to apply correction factors supplied with the calibration weight.
