This precision weight set is manufactured to fulfill the rigorous requirements of ASTM E617-23, "Standard Specification for Laboratory Weights and Precision Mass Standards." As an ASTM Class 0 set, it represents a high order of accuracy for calibration work, making it an essential tool for maintaining the integrity of sensitive analytical and precision balances. The use of polished stainless steel ensures long-term stability, corrosion resistance, and meets the specified density standard necessary for critical applications where air buoyancy corrections are applied.
Primary applications for this set include the calibration and routine performance verification of high-precision Class I and II balances. It is also employed for the tolerance testing of ASTM Class 4, 5, and 6 weights, serving as a trusted reference standard. Furthermore, its reliability makes it suitable for verification checks in quality control processes, student laboratories where proper technique must be taught, and rough weighing operations that still require a known reference point. The weights are marked with their nominal value for easy identification.
Custom configurations of this set are available as build-to-order items to meet specific user requirements. For sets with a largest weight exceeding 500 g, a dedicated hardwood case with velvet-lined pockets is provided. This particular 50 g set includes a precision-machined, polyvinyl crush-resistant case for secure storage and transport, ensuring the weights remain protected from damage and contamination.
