If you require a basic Certificate of Conformity on any of your M1, M2 or M3 Hexagonal Weight orders we can issue a JWS Certificate which will specify it complies with OIML accuracies. 

Certificates are individually serial coded, signed by the Calibration Manager, fully traceable and stored on our data base.

Certificates are not legally required for Trade Weights but we can issue one should you require it for Quality System auditing.   

You will only need to order one Certificate for a batch of weights, of different denominations on the same order.
