30 kg - 5 kg Single Calibration Weight, ASTM Class 1

Key Highlights

• Designed to meet the exacting tolerances of ASTM Class 1.

• Supplied as a single, heavy-capacity weight for efficient calibration.

• Nominal value is clearly marked on the weight for easy identification.

• Features a sealing cavity for adjusting material in 100 g or larger capacities.

• Constructed from material with a standardized density of 7.84 g/cm³.

This single calibration weight serves as a fundamental mass standard for calibrating and verifying the performance of scales with capacities at 30 kg, 25 kg, 20 kg, 15 kg, 10 kg, and 5 kg. Its classification to ASTM Class 1 specifications ensures it provides the high level of accuracy required for quality control procedures, legal-for-trade verification, and stringent laboratory applications where measurement traceability is paramount.

The weight is engineered with a durable, corrosion-resistant finish and includes a sealed adjustment cavity. This design allows for precise mass adjustment during manufacture to achieve the strict ASTM Class 1 tolerances and ensures long-term stability by protecting the internal adjusting material from environmental contamination. The standardized density minimizes the potential for errors due to air buoyancy during highly precise calibrations.
