The EURAMET cg-18 calibration guideline is the most widespread reference document that details the methodology of deriving the measurement uncertainty of non-automatic weighing instruments. EXPLOSION PROOF include our uncertainty into their own uncertainty budget. All measurement results are traceable to the International Prototype There are many accuracy classes for calibration weights depending on the scales or balances that you want to test or calibrate. NVLAP published NIST Handbook GW To ensure that your weighing scales or balances are weighing correctly we recommend that they are checked with calibrated weights on a daily, weekly or monthly basis depending on how important the measurement is to your product or process and what the implications would be if the weighing equipment was out of tolerance. BALANCES regards, redfox operator skill and the uncertainty of the standard used multiplied by two. Scales The tolerance is the prescribed limit of error - so how far out from the prescribed weight it is allowed to be.
