Carrying out of tests

The testing laboratory of JSC “PIC “Electropribor” (Certification licence No. 704 dated 03.06.2014, issued by the branch of the Federal State Budget-Funded Institution “46 Central research institute” of the Ministry of Defense of Russia) is equipped with testing facilities (more than 50 units), which allows mechanical and climatic effect testing, as well as the required equipment and measuring instruments to check tested products. The laboratory staff possessing the necessary professional training, qualification and experience, is certified for the right to carry out tests, fixed in the Field of certification of the testing laboratory.
