The National Institute of Standards and Technology (NIST) has implemented new requirements for Class F weights, used in precision measurements. The updates ensure accuracy and traceability in calibration processes. These regulations aim to address concerns regarding the consistency and reliability of weight measurements. NIST is actively working on revising specifications for Class F weights to enhance their quality and establish more stringent criteria for manufacturing and calibration. The ongoing efforts are expected to lead to improved measurement accuracy and promote uniformity in weight calibration across various industries.

Experts in precision weighing since 1939, the precision measurement team at Cross Company can answer any questions about choosing the right test weights for your process. Does this update put you in need of ASTM Class 6 scale weights, test weights, and weight sets? We are a proud representative for Troemner and offer a range of calibration weights, no matter what class is needed. Do you already have class 6 weights?
