Certificate of Metrology, also known as Pattern Approval Certificate, is a certificate for measuring instruments. Currently all the measuring instruments are certified and registered by “Committee for Technical Regulation and Metrology of the Ministry of Industry and New Technologies of the Republic of Kazakhstan”. The committee examines the applied measuring instruments, runs test and issues the certificates on the basis of the Law of the Republic of Kazakhstan “On Uniformity of Measurements” on June 7, 2000, N 53-II. Registered certificates are shown on the committee’s online database.

This certificate is required for all measuring instruments displaying certain measuring range and accuracy. This certificate is issued by each national Metrology Authority (Rosstandart in Russia, Committee of Technical Regulation and Metrology in Kazakhstan, State Committee of Standardization of Rep. of Belarus). It declares that the certified instrument:

  • is approved for operation as an official measuring device with the range and accuracy as stated in the appendix to the certificate;
  • approves calibration procedure to be followed during periodic calibration tests;


  • Weights and some similar measuring instruments related to the quantity of the goods in the domestic market;

  • Instruments for geodesic and hydrologic activities;
  • Instruments for ecological activities;
  • Instruments for labor safety;

  • Instruments for sports, Olympic measurements, etc.


Registered measuring instruments can be searched on the metrology committee’s online homepage by registration number, which are printed on certificate of metrology. Expiration date of certification is up to 5 years.

Certificates are issued with attachment documents, on which the applied area, purpose, inaccuracy, test interval and other information are shown. Registration of Metrology certification takes from 2 to 3 months.

There are two types of Metrology certificates:

  • “Batch (one shipment)”: Metrology certificate which is valid for a certain batch of instruments with serial numbers listed in the certificate.
  • “Type” (specific valid period): 5-year valid metrology certificate which can be issued after sample testing.
