The technical laboratory department plays an important role in the organization chart of ABB Brno, because all products of ABB are subjected from the very beginning of their development to stringent testing which is carried out there.
High level of the equipment together with a creative technical approach of an experienced laboratory staff gives guarantee for a high metrological precision of all measurements, which are performed there, including periodical tests of electrical devices and switchgears.
The Certificate of Accreditation was issued by Czech Accreditation Institute (CAI) under serial number 852/2015 and Technical laboratory ABB Brno obtain accreditation No. L1693.
