Pattern approval and verification of weighing instruments constructed from modules

摘要

The National Standards Commission has developed a system which allows the pattern approval and verification of weighing instruments constructed from modules. With the advent of electronic weighing instruments it has become practical to construct a variety of instruments from a wide range of modules such as load cells and digital indicators. The Commission's system enables these modules to be approved separately and various other certificates of approval to be issued, thereby allowing the modules to be combined into an instrument which may be verified in the field.
