This precision weight set is engineered as a primary reference standard for calibration laboratories, metrology departments, and quality control facilities where measurement uncertainty must be minimized. The set's adherence to ASTM E617-23 specifications for Class 0 tolerance ensures it meets the strictest requirements for mass accuracy, making it suitable for calibrating high-precision Class I and Class II balances, as well as for the tolerance testing of lower-class weights (such as ASTM Class 4, 5, and 6).
Each weight in the set features a polished stainless steel construction with a density of 7.95 g/cm³, providing superior resistance to corrosion and wear in laboratory environments. The weights are marked with their nominal value for easy identification. In accordance with ASTM E617-23 for Class 0, individual weights are not serialized; instead, a unique serial number is applied to the set's case, providing the necessary traceability. This 200 g set is housed in a precision-machined, crush-resistant case designed to protect the weights from damage and contamination.
