This Rice Lake calibration weight set is manufactured as a precise mass standard for use in laboratory, educational, and industrial environments. The set, spanning 2 lb through 50 lb capacities, is specified as ASTM Class 4, making it suitable for calibrating and checking scales designated as ASTM Class 4, 5, and 6. Its primary function is to provide a known, traceable mass to verify the accuracy of weighing equipment, perform routine tolerance tests, and ensure compliance in rough weighing operations or student laboratories.
Each weight in the set features a polished stainless steel finish, offering superior resistance to corrosion and environmental factors compared to plated or cast iron weights. The weights are marked with their nominal value for easy identification. In accordance with ASTM E617-23 for this class, the individual weights are not serialized; a serial number is applied to the accompanying case for traceability of the set as a whole. For secure organization and protection, the set is housed in a dedicated hardwood case with custom velvet-lined compartments.
