The Metrology Laboratory has been recognised as an accredited body since 2000. Therefore it operates on the basis of a management system compliant with the requirements of the PN-EN ISO/IEC 17025:2018-02 standard as regards the AP 024 accreditation.

The laboratory consists of two sections: Length and Angle Section and Electrical Quantities Section.

We offer services in the field of calibration of measuring instruments (within and outside the scope of accreditation), measurements, measurement consultancy and metrology training.

We cooperate with factories, laboratories and the Railway Research Institute's Quality and Certification Centre both in testing for certification and calibration.

We act impartial and confidential during and after the completion of each assignment.

We endeavour to continually improve our competitiveness by raising staff qualifications and extending the Laboratory's range of services, working to tight deadlines and maintaining attractive prices.

It is the only laboratory in Poland which is accredited for the calibration of measuring instruments intended for railway measurements.
