This SOP and logs provide procedures for calibration, verification and documentation of scales used for the receipt, processing, packaging, or distribution of components and finished products.

Refer to the SOP "General calibration procedures" for important additional information and definitions of specialized terminology used in this SOP.

The scale verification log can be used to record daily verification that scales are functioning properly. With some modifications, a similar form can be used to document scale calibrations (i.e adjustment of the scale to bring its readings within the required tolerances). Scales used for dispensing, analytical testing, and other critical functions should be verified or calibrated at least daily.

A scale daily check log is also provided.
