This 25 kg calibration weight is engineered as a precision mass standard, conforming to the exacting tolerances of ASTM E617-23 for Class 3. Its construction from polished stainless steel ensures superior durability and long-term stability, resisting corrosion in various working environments. The defined density of 7.95 g/cm³ allows for accurate air buoyancy corrections during high-precision calibration procedures.
Primary applications for this weight include the calibration of Class I and II analytical and precision balances, student laboratory use, and rough weighing operations in industrial settings. It is also essential for performing routine tolerance testing and verification checks on high-capacity scales. The inclusion of a dedicated storage case and handling glove safeguards the weight's critical surfaces from contamination and damage, preserving its certified mass value and supporting proper metrology practices.
