Uncertainty Test for Balance Calibration

Dear Expert,
I want to know that when we do the Uncertainity test for balance calibration, then what capacity or % of max. capacity, of wt. is taken for this test.
Plz tell the range for the balance having capacity 200gm, 2 kg, 10 kg, 50, 100, 500 kg. Then what is the std.
Plz also tell the guideline which cover this topic.

Thanku in advance.

Follow OIML guideline

There is no “test” named Uncertainty test for balance

Please see information about “estimating” uncertainty of balance from the Euramet CG-18
