What is the purpose of a calibration weight?

Calibration weights are precision mass standards used to verify and adjust the accuracy of weighing instruments, such as balances and scales, ensuring they provide correct measurements.

What does 'ASTM compliant' mean for calibration weights?

ASTM compliance indicates that the weight meets specific standards set by ASTM International for material, design, density, and tolerance, ensuring its suitability for precise calibration tasks.

How often should calibration weights be re-certified?

The re-certification interval depends on usage frequency, environmental conditions, and internal quality procedures, but typically ranges from 12 to 24 months to maintain traceability and accuracy.

Can this weight be used for any type of balance?

This 4KG weight is suitable for calibrating balances with a capacity that accommodates 4KG and a readability that aligns with the weight's ASTM class. Buyers should consult their balance's manual for specific calibration weight requirements.
