It’s important to calibrate scales at regular intervals to ensure they remain accurate. Stainless Steel Masses (Test Weights) are used in calibration and testing of scales. Masses (Test Weights) can be produced according to standards such as ASTM, OIML and NIST. From lowest (most accurate) to highest tolerance, the OIML classes are E1, E2, F1, F2, M1, M2, and M3. OIML class weights are more commonly used outside the US in Europe and Latin America.
