5 kg - 10 g Calibration Weight, ASTM Class 1

Key Highlights

• Designed to meet the exacting tolerances of ASTM Class 1 (E617).

• Supplied as a single weight kit including a protective case and handling glove.

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

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

• Manufactured to a density of 7.84 g/cm³ for superior performance.

• Optional serialization via stamping or laser marking is available (Class 2 to 4).

This 5 kg calibration weight serves as a fundamental reference standard for verifying the accuracy of high-capacity precision balances and scales. Its construction and certification to ASTM Class 1 specifications ensure it provides the minimal permissible uncertainty, making it indispensable for quality control, laboratory research, and compliance applications where measurement integrity is non-negotiable. The inclusion of a dedicated storage case and handling glove is a critical part of the kit, protecting the weight's surface from contamination and damage that could affect its mass value and traceability.

The weight incorporates a sealed adjustment cavity, a standard feature on 100 g and larger masses, which allows for precise factory setting to its exact nominal value. With a standardized density of 7.84 g/cm³, it minimizes the potential for air buoyancy errors during high-accuracy calibrations. For operations requiring individual weight tracking within a calibrated set, serial number marking is available as an optional feature to enhance asset management and documentation practices.
