Technical Control Department of Altai-Koks receives the international "Seal of Quality”

Technical Control Department of Altai-Koks has once again received a certificate confirming the quality of the laboratory testing of coal raw material and finished product - coke. This certificate is issued by .

Altai-Koks is the only coke producing enterprise in Russia, which is involved in the inter-laboratory comparative tests as part of the programmes to confirm the qualification by International Quality Control Laboratories LQSi and DCC; each time Altai-Koks received a certificate of achievement in the field of the quality of the product testing. This confirms the technical competence of Altai-Koks’ laboratory.

Several times a year the technical control department receives from the international laboratories samples of coal and coke to be analyzed according to certain parameters. The report with the test results is sent to the international service provider, which then sends the evaluation report with the information about the group average calculated rates and the results of the laboratory evaluation. The same report indicates dynamics, stability and deviation for each parameter, as well as violation of the rules (if any).

"This is a form of experimental check of our activities. The objective is to determine the technical competence of the laboratory and confirm compliance with accreditation criteria during the inspection control of our work. “This is the reason why we've been actively involved in the inter-laboratory comparative studies for six years,” comments Yelena Denisenko, the head of the expert analytical service at Altai-Koks.

Today, about 20-25 laboratories take part in the qualification certifying programmes all around the world. The results of the inter-laboratory comparative studies ensure the correct testing of products, as well as the accuracy and reliability of the results.


Technical Control Department is included in the Register of bodies for certification and accreditation of testing laboratories (centers) with the Federal Accreditation Service (Rosakkreditatsiya) and has a certificate of accreditation for compliance with ISO/IEC17025 international standard in the German Testing Accreditation Body DakkS GbmH. Any accredited laboratory has to participate in inter-laboratory comparison tests.
