The NDN Calibration Laboratory has been in business since the 1990s. Our many years of experience in the field of measurement are reflected in the high quality of services offered to our clients. Qualified personnel, high-end equipment and an effective management system ensure attention to the smallest details and continuous development of the Laboratory. 

We issue electronic certificates that can be sent to clients by email or on CD!

Accreditation

In order to confirm the competence of the NDN Calibration Laboratory, the team began the accreditation process at the beginning of 2022. Finally, the accreditation certificate with the number AP 209 granted by the Polish Centre for Accreditation (the only body authorised to grant accreditation in Poland) was obtained by the Laboratory in July 2022. At the same time, compliance with the requirements of the PN-EN ISO/IEC 17025 standard 'General requirements for the competence of testing and calibration laboratories.

Scope of accreditation

 Certificate  

Metrological traceability and validity of results

The management system implemented at the Laboratory, in accordance with PN-EN ISO/IEC 17025, includes a calibration program of test and measurement equipment serving as measurement standards. The Laboratory declares to have up-to-date calibration certificates issued by accredited calibration laboratories. Copies of these are available on request.

An important point testifying to the competence of personnel and meeting quality requirements is the established plan for confirming the validity of results. The NDN Calibration Laboratory, while carrying it out, participates in proficiency tests and inter-laboratory comparisons (PT/ILC) organised in accordance with the requirements of PN-EN ISO/IEC 17043. In addition, we have implemented a number of organised internal checks aimed at regular control and analysis of technical activities at the Laboratory.

Equipment

Laboratory is equipped with high-end equipment. The calibrators, decades and multimeters used for calibration are periodically calibrated in accredited laboratories.

Our standard units

•          Calibrator Fluke 5520A with scope option 1,1 GHz
•          Calibrator Meatest 9010
•          Electrical tester Fluke 5322A
•          Decade capacitor ZELAP typ CD-5b, abs. cert. 1,5
•          Resistor ZELAP typ RN-2-W 10MOHM , abs. cert. 0,05
•          Multimeter Keysight 34470A
•          Frequency meter Hameg HM8123
•          Signal generator Ceyer 1465D

The laboratory constantly monitors the atmospheric conditions in the room where the measurements are taken.

Statement of conformity

The NDN Calibration Laboratory issues certificates with a statement of conformity to specification, which are required if the client has implemented a quality system in accordance with ISO standards. A statement of conformity is also advisable if the customer is keen to regularly check the correct functioning of its equipment. A statement of conformity is carried out for an additional fee, which can be included in the quotation at the customer's request. The decision-making method for the statement of conformity is in accordance with document ILAC-G8:09/2019.
