Pattern Approval Certificate of Measuring Instruments (Metrological Certificate for Russia and EAEU)

Metrology Pattern Approval Certificate (MPA/PAC) approves that the certified measuring instrument meets all the requirements established for this type of measuring equipment, safety standards,  has successfully passed both technical and measurement tests and is in the margin of error.A measuring instrument is a tool (instrument) used to determine the values whose units of measurement are used in the Russian Federation according to the established rules.

Measuring instruments must meet the established requirements and have certain performance metrological and technical characteristics in order to be approved within the Russian territory. This correspondence establishes the metrological certificate.


Voluntary Metrological Certification was established in 2001 by the Federal Acts No. 4871-1 of April 27, 1993 and No. 5151-1 of July 10, 1993. Operating in accordance with Article 24 of the Law of the Russian Federation “On Ensuring the Uniformity of Measurements”, it is applied for certification of measuring instruments in Russia, which are not subject to mandatory state regulation.

The applicant (manufacturers, suppliers and users) initiates voluntary metrological certification of measurement instruments. It is to confirm the compliance of products with metrological standards, specified standards, technical conditions and other documents. However, it cannot be a substitute to obtain a mandatory Metrological Certificate of Measuring Instruments (MPA), which is under the legislation of the Russian Federation.


Obtaining a metrological certificate is mandatory for measuring instruments involved in:

  • Defence of the State;
  • Security;
  • Medicine;
  • Regulation of uniformity of measurements;
  • Cartography;
  • Geodesy;

SERCONS with accreditation in the field of metrology provides services for certification of measuring instruments fast, efficiently and with a competitive price. We issue a Certificate of Approval based on the results of measurement tests conducted in our own and accredited testing laboratory.

Measurement instruments are thoroughly examination during the certification process to identify its measuring range and other metrological parameters. Measuring devices are checked for sensitivity and measures to determine the true value, errors and other features.

Procedure for obtaining a Metrology Certificate:

  1. submission and consideration of an application;
  2. decision made by Rosstandart followed by notification of the applicant;
  3. testing process;
  4. certification of the quality system or production which depends on certification scheme;
  5. evaluation of the results and decision of the Rosstandart on the approval or rejection of the conformity document for the measuring instrument;
  6. registration of test materials;

  1. Verification of measuring devices is a set of procedures carried out by bodies of state metrological services (The Federal Office for Technical Regulation and Metrology (Rosstandart)) in order to determine and approve the conformity of the measuring device metrological characteristics with the specified requirements.
  2. Calibration of measuring devices is a set of procedures carried out to determine the true value of the measuring devices characteristics.

Verification and calibration procedures are regulated by the Law of the Russian Federation of 26 June 2008 N 102-FZ «On ensuring the unity of measurements» and several sub-decrees.

The term of «calibration» and «verification» is not very clearly delineated in the normative documentation. The verification procedure is carried out if the measuring devices are entered in the State Register of Measuring Instruments. If the measuring devices are not recorded in this register, they must be calibrated.
