This individual calibration weight is manufactured to the exacting requirements of ASTM E617-13, classifying it as a Class 1 standard, the highest grade for general laboratory use. Its exceptional accuracy is indispensable for the calibration, verification, and routine testing of high-precision analytical and semi-micro balances. The use of stainless steel with a polished finish ensures long-term stability, corrosion resistance, and ease of cleaning to maintain metrological integrity.

The weight is associated with a serialized storage case (sold separately) for proper traceability and protection. With a standardized density of 7.95 g/cm³, it allows for accurate air buoyancy corrections when performing high-accuracy mass comparisons. This weight serves as a fundamental reference standard in quality control laboratories, calibration facilities, and research institutions where measurement certainty is paramount.
