What is E1 Class 5 kg?

E1 Class 5 kg is a precision calibration weight used to verify and calibrate weighing balances and scales. It conforms to OIML E1 class tolerances and serves as a traceable mass standard in metrology laboratories.

Why is it used?

Calibration weights like E1 Class 5 kg are essential for maintaining measurement accuracy in analytical balances, industrial scales, and quality control systems. Regular verification with certified weights ensures compliance with ISO 17025, GMP, and NABL requirements.

How does it work?

The weight is placed on the balance pan to verify the instrument reads the known nominal mass value (5 kg). Any deviation beyond the E1 class tolerance indicates the balance requires adjustment or recalibration.
