The RUSSIAN METROLOGICAL CERTIFICATE is known as the Pattern Approval Certificate (PAC) and is a national certificate of conformity, i.e. a certificate that is required for measuring instruments to be used in all fields defined by the Metrology Law, i.e. to be used in the field of Legal Metrology.
The approval, and issuance of the certificate, of measuring instruments in the Russian Federation is valid for 5 years for a given model and has a complex procedure. This consists in the compilation of technical documentation and manuals (which may consist in a new draft or in the adaptation of existing documentation to local standards), the drafting of the calibration plan, the evaluation of the conformity of the instrument at a Russian metrological institute or laboratory. This is followed by registration with the Federal Agency for Technical Regulation and Metrology, i.e. the Russian Standards Agency.
The type/model approval certificate of an instrument states

  • The description and identification code of the instrument;
  • The name of the manufacturer;
  • The repertory number of the instrument;
  • The calibration interval and the details of the metrological confirmation plan.

The certificate shall be accompanied by a technical annex specifying the field of application, the essential technical and metric characteristics, the margin of inaccuracy, the name of the normative document of compliance with which the acceptance tests were carried out.

There are two types of metrological certificate:

  • The serial certificate, this type of certificate is valid for 5 years. Instruments manufactured with this certificate are considered to be of an approved type and may bear an approval mark. In this case, the certificate is issued to the metric manufacturer;
  • The certificate for a single order, or individual serial number, does not expire. The instruments are approved for the duration of their use and the certificate is issued to the importer or end user.


Poverka” is the initial verification that applies to products already included in the metrological certificate obtained. There is the initial “Poverka”, i.e. measuring instruments subject to calibration must undergo an initial calibration before being put into service, or after a repair; and the periodic “Poverka”, i.e. periodic calibrations for their metrological confirmation.
The metrological institute establishes the metrological confirmation intervals following the approval tests, these intervals are then indicated in the model approval certificate. The initial calibration of measuring instruments of foreign manufacture is carried out at Russian metrological laboratories, by physically presenting the instrument to be calibrated with a valid metrological certificate.


All documents must be translated into Russian and must have stamps and signatures of the legal representative on all copies of the documents.
The required documentation includes:

  • Sample equipment for testing;
  • Detailed description;
  • Test reports of internal tests;
  • Advertising material;
  • Instruction for use;
  • Existing certificates;

Medical measuring instruments need the approval of the Russian Ministry of Health;

The list may change and extend depending on the field of application.

The Certification Procedure

The procedure for applying for a certificate varies for single deliveries or for series production. For the latter, an on-site production audit is mandatory in order to obtain a certificate. The metrological engineering certification procedure follows a precise course: the application for certification is made, followed by laboratory tests, analysis and evaluation of test protocols, a decision by the Russian Standards Institute (Rosstandard) on the rejection or approval of the measuring instrument, and then the certificate is issued.

According to the national law of the Russian Federation, in the vast majority of areas subject to state supervision, only certified and, of course, approved measuring instruments may be used.
This includes areas such as public health, veterinary medicine, trade, cartography and geodesy, occupational safety, and environmental protection, and the instruments used in these areas are subject to mandatory regular monitoring by the Russian Federal Office (Rosstandart) and each instrument is then entered in the respective state register. The Russian Research Institute for Standardisation and Metrology is obliged to have a register of approved measuring instruments.

Voluntary Metrology Certification

The voluntary metrology certificate serves for measuring instruments that are not subject to mandatory metrology surveillance and certification. The voluntary certificate does not replace the approval and registration of measuring instruments if these are required by law.
Voluntary certification can only be carried out by certification bodies and testing laboratories accredited by Rosstandard. This type of certification starts with the person placing the measuring instrument on the market (or the manufacturer himself) and is carried out to confirm the conformity of the measuring instrument with the requirements of the technical regulations and to gain consumer confidence.
