Troemner Resource: Status of NIST Class F Weights and Updated Requirements 1

Overview

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?

Did you know… Cross Company is an ESOP (Employee Stock Ownership Plan). Our ESOP started in 1979 and as of 2006, we are 100% employee-owned! Learn more about our ESOP and how that benefits both team members and our customers.
Did you know... the precision measurement group at Cross was founded in 1939 by our current CEO's grandfather, Jim King. That's a whole lot of calibration!
Did you know... A fingerprint weighs about 50 micrograms. We know, we weighed it! The residue left from a finger can actually make a difference in weight results which is why we wear gloves when we calibrate weights. For reference, a sheet of paper is about 4.5 grams, that’s 4.5 million micrograms.
Did you know… Cross Company has grown significantly since our start in 1954. Over the years we've acquired 26 companies! Today, our five groups have expertise in everything from industrial automation to precision measurement, and industry knowledge going all the way back to 1939.
