Since 30 October 2006 the Measuring instruments directive (MID) is applied in the member states of the EU. This directive regulates the first placing on the market of measuring instruments subject to mandatory verification by so called conformity assessment procedures. Automatic weighing instruments are covered by the MID, non-automatic weighing instruments are covered by the directive for non-automatic weighing instruments, which entered into force in Austria in the year 1994. Hence they can be placed on the market for the first time without further national type approval and initial verification. The assessment of conformity is equal to the initial verification.
Applicable as conformity assessment procedures are: For mechanical automatic weighing instruments the modules B+D, B+E, B+F, D1, F1,G or H1, for electro-mechanical automatic weighing instruments the modules B+D, B+E, B+F, G or H1, for electronic automatic weighing instruments or instruments containing software, respectively, the modules B+D, B+F, G or H1.
For non-automatic weighing instruments the procedures EU type approval, EU declaration of conformity, EU verification and EU unit verification are possible.
Automatic instruments for weighing road vehicles are not subject to a directive but to national regulations.
Weights are generally approved for verification if they fulfil certain regulations for the quality.
The new and subsequent verification of all weighing instruments and weights are subject to national regulations and is carried out in Austria by accredited verification bodies.The interval for subsequent verification is generally 2 years for weighing instruments and weights.
