67 Mechanical testing of mechanical engineering products constitutes one of the key elements in assessing the technical conformity of products with established requirements. Such testing includes determining material strength, operational reliability of components and assemblies, in accordance with standardized methodological requirements. National standards governing these testing procedures must be aligned with QMS requirements, as test results form the evidentiary basis for assessing product compliance with contractual and standard requirements [4]. A QMS in accordance with ISO 9001 requires documentation of procedures, control of processes and testing, maintenance of records, and analysis of results, thereby creating the foundation for implementing harmonized national standards of mechanical testing into everyday production practice. In the contemporary context of industrial development, the harmonization of mechanical testing standards extends beyond a purely technical task and becomes an element of the strategic quality management of a mechanical engineering enterprise. While at the operational level mechanical testing ensures confirmation of product conformity with established requirements, at the strategic level it forms the basis for long-term competitiveness, risk management, and increased trust from customers and partners. Within the framework of strategic quality management, the harmonization of standards performs the functions presented in Figure 1.
