Legal metrology

The basic principles of legal metrology are stipulated by the Units and Time Act and the Measurement and Verification Act, including the relevant implementing ordinances and additional regulations. The physical and technical basis of the units to be applied in official and commercial transactions is today’s International System of Units (SI).

The tasks of legal metrology are distributed between the federal and the state authorities. PTB is responsible for type examination and conformity assessment of measuring instruments and traceability to national standards used by the verification authorities. The verification authorities of the sixteen federal states and the officially approved test centers for measuring instruments in the field of electricity, gas, water and heat are responsible for the individual testing of measuring instruments subject to mandatory verification.
