Key Highlights

• Designed to meet ASTM E617-23 specifications for Class 3 weights.

• Manufactured from polished stainless steel for durability and corrosion resistance.

• Nominal value clearly marked on each individual weight.

• Density of 7.95 g/cm³ for accurate use in standard air density applications.

• Serial numbers applied to the storage case for complete traceability.

• Weights may be marked with an identification symbol for inventory control.

This calibration weight set is a fundamental tool for maintaining measurement accuracy in environments that utilize heavy-capacity scales, such as industrial batching, freight weighing, and large-capacity force measurement. The set's classification to ASTM E617-23 Class 3 tolerances ensures it is suitable for calibrating, checking, and verifying scales where high precision is mandated for quality control, trade, and process adherence.

Crafted from high-quality stainless steel with a polished finish, the weights offer exceptional resistance to environmental factors that can compromise mass stability. The specified material density of 7.95 g/cm³ allows for reliable performance under normal atmospheric conditions without the need for complex buoyancy corrections in most settings. Each weight is clearly marked with its nominal value, while the serialized case provides the documentation trail necessary for audit-ready calibration protocols and asset management.
