The table above is a listing of the tolerances of various classes of masses. The weight value can deviate above or below the nominal value by the tolerance defined. To determine the tolerance of a mass, look at the denomination or nominal value of the weight and the appropriate class you need.

All calibration weights are not returnable. The reason for this is some people think nothing to order calibration weights to calibrate their scale and then return the calibration weights since now their scale is all calibrated. These are the same people that buy a ladder at Home Depot, paint their house using the ladder, and spill a few gallons on the ladder and then return the ladder telling Home Depot the ladder isn't quite what they expected. Plus what are you mad about I'm returning the ladder in 10 days well under your 30 day limit. It is truly sad and bad how many ruthless people there are and it seems the internet has a greater portion of people like this since they don't have to face a person and basically tell them thanks for letting me use the weights for free.
