Design and development support

Streamline your product development through an understanding of requirements and standards: from drawing board to initial use

Over 50% of all OIML certificates are issued by NMi

NMi is the unrivalled market leader in internationally accepted OIML certificates for NAWIs and AWIs.

Independent view on your specifications

As an independent party, NMi can take a neutral stance when preparing specifications and evaluating your specifications.

Insight into new developments in legislation and standards

NMi plays an active role in important national and international standards organisations such as EN, WELMEC and OIML and is therefore the first to know about developments.

NMi provides support in different phases of product development, helping you avoid expensive and time-consuming modifications later on.

Design and standards

You can take into account the requirements relating to your weighing instrument during the very earliest stages of product development. This enables you to reduce development costs as well as the time between design and final product according to the requirements. The result is fewer failures and therefore less retesting during certification.

Correctly interpreting standards and legislation is a challenge in itself. However, this is routine for NMi’s specialists. NMi is represented in various national and international committees, so we know exactly what future developments can be expected. We can tell you now what changes in requirements or standards will take place during the coming year. This knowledge and experience is then incorporated in your design specifications. As an independent party, NMi also performs a design review to predict whether certification will be successful.

After the clear explanation about the interpretation of the standards, I saw a new opportunity to simplify and improve my design at the same time.


A pre-test may be performed during the development of a prototype. This makes it possible to identify potential obstacles or test failures in the later certification process at a stage when modifications are still relatively straightforward. It is then easy for our team of engineers to conduct type examination and certification. More information about testing and certification is available here.

Manufacturer verification

In order to speed up the commissioning and supply of your product, you may conduct the first verification of the measuring instruments yourself (for Europe in accordance with MID Module D and NAWI Directive Annex II). NMi also performs acceptance tests on behalf of purchasers of meters by testing production samples.
