Wire weights for calibration
Weights intended to ensure traceability between the national weight standards (the values of which are derived from the International Prototype of the Kilogram) and E2 class weights and lower. These are also used for microbalances.
Weights intended for use in the verification or calibration of Class F1 weights and for use with weighing instruments of special accuracy class I.
The Class E1 and E2 weights or weight sets are always accompanied by a calibration certificate.

Wire weights for calibration
Class: E1
Weights intended to ensure traceability between the national weight standards (the values of which are derived from the International Prototype of the Kilogram) and E2 class weights and lower. These are also used for microbalances. The Class E1 weights or weight sets are always accompanied by a calibration certificate.
