The Rice Lake ASTM Class 3 Weight Set serves as a trusted reference standard for a wide spectrum of verification and calibration tasks. Its adherence to ASTM E617-23 specifications ensures it meets the rigorous demands for calibrating Class I and Class II balances, performing routine tolerance testing, and conducting essential verification checks in quality control and laboratory settings. The set is also ideally suited for student laboratory use and rough weighing operations where a known traceable standard is required.

Crafted from durable stainless steel with a polished finish, these weights offer long-term stability and corrosion resistance. The nominal value of each weight is permanently marked for clear identification. For sets with a largest weight of 500 g, the weights are securely housed in a precision-machined, polyvinyl crush-resistant case, providing protection and organization. Custom configurations are available to build a set tailored precisely to your specific calibration requirements.
