F1 weights

Weights for analytical and precision balances of accuracy class I/II ≤ 100 000 (e)

Control weights of accuracy class F1 may be used for checkweighing on scales of accuracy class I or II whose verification interval is greater than or equal to 100 000 (e). This type of weights is especially intended for precision and analytical balances in laboratories and research. For this type of weights we recommend the use of suitable handling tools and also suitable storage of the weights in a case or box to prevent damage and unwanted deviation.
