What Is an F1 Class Weight Box?

F1 Class Weights are precision calibration standards used for routine balance calibration and verification in laboratories and industries.
They are slightly less accurate than E2 weights but still meet the strict OIML-R111:2004 criteria.
F1 Class Weights are ideal for verifying analytical and top-loading balances where high precision is required but E2-level accuracy is not necessary.

 

Construction and Quality Control

Each F1 Class Weight Box from V-CARE IMPEX is manufactured using austenitic non-magnetic stainless steel to ensure stability and corrosion resistance.
The weights are precisely machined, hand-polished, and passivated to remove magnetic residues, guaranteeing accuracy and long-term performance.
Each piece undergoes density, magnetism, and dimensional verification before certification.

​

Calibration and Recalibration Services

V-CARE IMPEX provides recalibration and maintenance for F1 Class Weights through accredited NABL calibration laboratories.
We ensure your weights remain within tolerance limits, offering recalibration intervals as per your industry standards.
Clients can return old weights for adjustment or certification renewal at discounted rates.
