International Organization of Legal Metrology (OIML)

OIML is an intergovernmental treaty organization addressing legal metrology, including provisions related to units of measurement, to measurement results (e.g. prepackages) and to measuring instruments. These provisions cover the legal obligations related to the measurement results and the measuring instruments, as well as the legal control which is performed by or on behalf of the government.
