50 lb - 1/16 oz Single Calibration Weight, ASTM Class 1

Key Highlights

• Designed to meet ASTM E617-13 specifications for Class 1 tolerances.

• Stainless steel polished finish for durability and contamination resistance.

• Nominal value marked on weights for immediate identification.

• Serial numbers applied to case for full audit trail and traceability.

• Supplied as a single weight for targeted calibration tasks.

• Density of 7.95 g/cm³ for precision mass calibration.

This 50 lb Class 1 calibration weight serves as a primary reference standard for the most demanding calibration environments. Manufactured from high-grade stainless steel with a polished finish, it is engineered to resist corrosion and minimize surface adsorption, ensuring long-term mass stability. Compliance with ASTM E617-13 ensures it meets the rigorous tolerances required for calibrating high-capacity analytical and industrial balances where regulatory compliance is critical.

The weight is clearly marked with its nominal value, and the included storage case features an applied serial number. This practice provides a direct chain of custody and traceability, which is a mandatory requirement for ISO/IEC 17025 accredited laboratories and quality systems subject to audit. The defined density of 7.95 g/cm³ allows for precise correction in air buoyancy calculations, further enhancing measurement accuracy during the calibration process. Its role is indispensable in applications ranging from pharmaceutical batch weighing to the calibration of industrial force measurement devices.
