In applications where NIST Class F weights were formerly used, stainless steel ASTM Class 5 field calibration weights are ideal. Field calibration weights can be used for accuracy verification procedures for a variety of scales and balances.

ASTM Class 5 avoirdupois calibration weight sets are used for testing non-classified scale equipment, field standards for Class III scales or balances and tolerance checking.
