NIST Class F
NIST Class F calibration weights are used primarily to test commercial weighing equipment. These tests for calibration purposes can be performed by in house technicians, maintenance workers, local weights and measures officials, device installers, and service technicians. Class F weights can be used for testing most Class III scales, all Class IIIL and Class IIII scales, and all scales not marked with a designated class. For more questions about calibration weights and what kind would be best for you application, please contact us.
