66 The production of mechanical engineering products is characterized by high requirements for quality, reliability, and safety. In the context of international trade and cooperation, it is essential to ensure that product testing – particularly mechanical testing – meets the level of requirements established by international standards. Compliance of national standards with the requirements of ISO 9001:2015 is a key factor in strengthening the position of Ukrainian enterprises in global markets and ensuring product competitiveness. In this regard, the harmonization of standards becomes a relevant direction for improving the product quality regulation system. The harmonization of national standards is understood as the process of aligning their requirements with international and European standards, thereby ensuring a common technical basis for conformity assessment of products. Within the European Union, a large number of harmonized standards are in force, including safety requirements and testing methods for machinery and mechanisms, among them mechanical testing methods as part of the certification process for mechanical engineering products [1]. In Ukraine, harmonization efforts are likewise aimed at adopting national standards identical to international ones, particularly in the fields of testing and quality management. These processes are implemented within the framework of the national standardization policy and the adoption of ISO standards as national standards, including DSTU ISO [2]. The international standard ISO 9001 establishes requirements for a quality management system (QMS) applicable to any organization regardless of its size, type of activity, or the products it manufactures. ISO 9001 defines quality management principles that ensure an enterprise’s ability to consistently supply products meeting customer requirements and applicable legal regulations [3; 5]. The harmonization of national standards with ISO 9001 involves not merely translating the international document but also adapting QMS requirements to the national context, testing and measurement methods, and the documentation of enterprise processes.
