These weights are of highest metrological accuracy class and used as primary reference standards for calibrating other lower class reference weights like E and blow classes , E class weights are integral /single piece monobloc type weights , E class weights have no method of adjustment. These weights are appropriate for calibrating high precision analytical balances with readability as low as 0.1 mg to 0.001 mg
