Complete Overview

This 25 kg calibration weight serves as a trusted reference standard for high-capacity scale calibration, testing, and quality control procedures. Manufactured to comply with the stringent requirements of ASTM E617-23, it ensures that industrial scales, floor scales, and other heavy-capacity weighing systems operate within their specified legal-for-trade or process control tolerances. The Class 2 designation indicates its suitability for calibrating high-precision instruments where strict accuracy is paramount for compliance and operational integrity.

The weight is machined from solid stainless steel, offering excellent resistance to corrosion and environmental factors that could affect mass stability. Its polished finish facilitates cleaning and inspection, while the stamped nominal value allows for quick identification. The specified material density of 7.95 g/cm³ is critical for performing advanced air buoyancy corrections in laboratory and metrology settings, enabling technicians to achieve the highest possible accuracy in mass determination.
