The Rice Lake 20 kg and 25 kg ASTM Class 2 Calibration Weight Sets are fundamental tools for maintaining measurement accuracy in industrial, educational, and commercial settings. Manufactured from high-grade stainless steel with a polished finish, these weights are built to withstand frequent handling while resisting corrosion. The specified density of 7.95 g/cm³ ensures consistent performance under standard atmospheric conditions, making them a trustworthy reference mass.
These sets are precisely engineered to comply with ASTM E617-23 standards for Class 2 tolerances, making them suitable for a wide range of critical tasks. Primary applications include the calibration and routine verification of Class I and Class II balances, as well as serving as a known reference for testing ASTM Class 4, 5, and 6 weights. Beyond formal calibration, they are equally valuable for student laboratories, rough weighing operations, general tolerance testing, and daily verification checks to ensure weighing equipment remains within specified parameters.
Explore custom configuration options for your specific needs. Custom sets are available as build-to-order items. Note that ASTM weight sets with a largest weight exceeding 500 g include a durable hardwood case with velvet-lined pockets, while sets with a 500 g largest weight are supplied in a precision-machined, polyvinyl crush-resistant case.
