25 kg - 1 g Calibration Weight, ASTM Class 4

Key Highlights

• Designed to meet ASTM E617-23 specifications for Class 4 tolerances.

• Constructed from high-grade stainless steel with a polished finish.

• Nominal mass values are clearly marked on the individual weights.

• Serial numbers are applied for traceability (case included; case sold separately).

• Density of 7.95 g/cm³ minimizes buoyancy correction calculations.

This comprehensive weight set serves as a fundamental tool for the calibration and verification of industrial bench, floor, and portable scales with capacities at or above 25 kg. Engineered to the rigorous tolerances defined by ASTM E617-23 for Class 4, these weights are suitable for a wide range of commercial applications where reliable weight measurement is critical to process control, inventory management, and quality assurance protocols.

The set's construction from high-quality, corrosion-resistant stainless steel ensures long-term stability and durability in demanding environments. The polished finish aids in cleanliness and inspection. Each weight is clearly marked with its nominal value, and the set is accompanied by serialized documentation (case sold separately) to support measurement traceability and quality system requirements. A defined density of 7.95 g/cm³ provides consistency, simplifying critical air buoyancy corrections during high-accuracy calibration procedures.
