Tasks

It is the main task of this division to carry out research and development work in order to improve its measuring procedures, measuring equipment and primary standards with a view to calibrating reference standards for industrial metrology in accordance with units and measurands agreed on the international level. This link-up (traceability) to national standards contributes to assuring the quality of industrial products.

Further tasks:

cooperation in the determination of fundamental constants
responsibility for the centralized manufacture of instruments
