This comprehensive 2 lb through 50 lb weight set is manufactured to conform with ASTM E617-23 standards for Class 3 tolerances. The polished stainless steel construction ensures long-term durability and resistance to corrosion in laboratory and industrial environments, providing a stable mass standard for repeated use. Each weight features its nominal value marking for clear identification during procedures.

Engineered for practical metrology applications, this set serves as a fundamental tool for the calibration of Class I and II precision balances. Its primary uses extend to performing routine verification checks, tolerance testing on scales, and serving as a reliable reference for higher-class weight sets (ASTM Class 4, 5, and 6). Furthermore, the set's robustness and clarity make it an excellent choice for educational settings in student laboratories, where it facilitates hands-on learning for rough weighing operations and fundamental mass comparison techniques.
