Hi,
We currently purchase Class 0 weights to verify our analytical balances which display up to 4 decimal places. We are trying to ascertain which tolerances to use while verifying them since the values given on the traceable weights certificate (derived from ASTM E617) are extremely stringent to 6 decimal places. What do you all use as a guide to verifying balances since we do not have a recognized National Metrological Institute where we live and the cost is extremely high for calibrating weights/balances overseas.
