Technical Specification

Each classification specifies maximum error discrepancies from a nominal value. The classification given to a calibration weight also depends upon its material, density, corrosion resistance, hardness, wear resistance, brittleness, magnetic properties, construction, and surface finish.

F2
Notation High precision weights suitable for very accurate precision balances. Ideal weight classification for weighing applications involving high value commercial transactions, e.g. precious stones.
Error Discrepancy The maximum error discrepancy from nominal value at 1 kg is 16mg.
Material 1mg to 5mg Aluminium, 10mg to 500mg Nickel Silver, 1g to 20kg Stainless Steel.
