This Recommendation prescribes the principal metrological static requirements and static evaluation procedures for load cells used in the determination of conformity to this Recommendation. It is intended to provide authorities with uniform means for determining the metrological characteristics of load cells used in measuring instruments that are subjected to metrological controls. It is acknowledged that test procedures found in OIML R 60-2 are useful in the evaluation of load cells that are currently in service (i.e. primarily of the strain gauge design) however, there may be variations in designs for load cells that will require additional or modified test procedures to appropriately evaluate them. These additional test procedures may be annexed when necessary. Except where otherwise specified, these requirements apply regardless of the technology or operating principle employed. The requirements and evaluation procedures in this Recommendation have been drafted to be non-specific with regard to load cell design and their operating principles.
