These weights are of the highest metrological accuracy class and are used as primary reference standards for calibrating other lower class references weights like E2 and blow classes, E2 class weights are integral /single piece monobloc type weights, and E2 class weights have no adjustment method. These weights are appropriate for calibrating high-precision analytical balances with a readability as low as 0.1 mg to 0.001 mg.
