Calibration Weights

Calibration weights are required in labs as they help ensure that lab balances are giving you accurate readings. However, they are not all made the same. Calibration weights are assigned a class which is based on the accuracy or tolerance of the weight. There are different sets of classes of weights, including ASTM, OIML, and NIST. In addition, there are certifications granted to different weights.
