Specifies a method of calibration for strain gauge load cell systems for use in various industrial weighing and force measurement applications.

This British standard describes a method of calibration for strain gauge load cell systems for use in various industrial weighing and force measurement applications.

NOTE The technical procedures covered in this British standard are split into one “standard calibration?? (Clause 7), which determines the basic response of the system in terms of non-linearity and reproducibility, and a number of “supplementary calibrations?? (Clause 8 to Clause 22), each of which determines the response of the system to one specific input factor. It is envisaged that load cell systems calibrated in accordance with this standard will normally undergo the standard calibration, possibly together with a number of supplementary calibrations, but a system may also be calibrated solely in accordance with one or more of the supplementary calibrations.
