In 2025, five key enterprises of TMH Group — Bryansk, Demikhovsky, Tver and Novocherkassk Electric Locomotive Plants, as well as Kolomna Plant — successfully passed certification in the field of non-destructive testing (NDT). Special attention was paid to equipment modernization: modern automated magnetic particle flaw detectors of the "YerMag" brand were purchased for the Tver and Novocherkassk plants.
The new installations will improve the accuracy and speed of inspection of critical components, including parts for promising hydrogen rolling stock.
Updated technological instructions for non-destructive testing have been developed and implemented at the Kolomna Plant, Demikhovsky, Tver and Novocherkassk enterprises. The list of controlled components has been expanded — it now includes elements of an innovative train on hydrogen fuel cells, which is being developed as part of the "green" technology strategy in the railway industry.
Following the audit, all five laboratories received official certificates of accreditation, confirming their competence and readiness to ensure high quality control of manufactured products.
