Comprehensive services in areas of testing, inspection, certification and training.


Dear clients and business partners of SZU

This year it´s been 50 years since the original name of the „Kovotechna Plant“ was replaced by the current one, i.e. by „Engineering Test Institute“ (SZU). It did not mean establishing a completely new enterprise, but rather the emergence of SZU from the then existing Kovotechna Plant state enterprise, which was a continuation of the previously established company. Our history, therefore, goes back much further than just those 50 years.

The beginnings of our company date back to 1898, when the „Provincial Institute for Promotion and Development of Trade and Small Enterprises at Chamber of Commerce“ was established in Jablonec nad Nisou in 1919, followed by the establishment of the same Institute also in Brno. In this arrangement, both those institutions functioned until 1950, when they were incorporated into Kovotechna Plant enterprise.

In 1997, SZU obtained its authorization from the Czech Office for Standards, Metrology and Testing (UNMZ), and since then we have become the Authorized Body No. 202 (AO 202).

Later on, in 2002, based on the UNMZ´s notification to the EC Commission, we became also the Notified Body No. 1015 (NB 1015) for conformity assessment of products.

Our long history record is primarily understood by us as being a commitment to continuous improvement of the services we offer, so that we continue to be to you a sought-after partner in the field of testing, certification, inspection and training.

In order to constantly improve our services, it is very important for us to know your opinion. Should you have any comments or suggestions, please, share them with us either by filling in the Questionnaire here or by emailing to
