This Rice Lake calibration weight set is constructed from durable stainless steel, providing a robust and corrosion-resistant solution for field metrology work. Each weight in the set is manufactured to conform to the strict tolerances outlined in ASTM E617-23 for Class 5, as well as NIST Handbook 44 requirements. This ensures the set serves as a trustworthy reference mass for verifying the accuracy of Class III commercial weighing devices, such as bench and portable scales used in various industrial and logistical settings.

The primary application for this set is as a practical field standard for routine performance testing. Technicians and quality assurance personnel rely on these weights to perform quick checks, verify calibration, and ensure scales are operating within their specified tolerances. The inclusion of a sealing cavity on most weights allows for professional adjustment should it ever be required, supporting long-term mass stability. With nominal values permanently marked, the set is straightforward to use, promoting efficiency and reducing the potential for error during testing procedures.
