70 - ensures compliance with international technical regulations; - expands export opportunities. For mechanical engineering production, which is characterized by a high level of product responsibility, the strategic role of standards harmonization is particularly significant, as product quality and reliability directly affect the operational safety of technical systems. Therefore, the harmonization of national standards for mechanical testing with the requirements of ISO 9001 is of significant importance for ensuring the quality and safety of mechanical engineering products and their compliance with international norms. Such a process contributes to improving the effectiveness of the quality management system, ensuring transparency of testing procedures, and facilitating the mutual recognition of results between national and international certification bodies. Manufacturers gain tools for standardizing approaches to quality control, documentation, and data analysis, which promotes the optimization of production processes and reduces the risks of product nonconformity with customer requirements. Further scientific and practical research should be aimed at: - analyzing the impact of standards harmonization on the competitiveness of mechanical engineering products in international markets; - developing methodological recommendations for adapting national mechanical testing standards to the requirements of ISO 9001 across various branches of mechanical engineering; - evaluating the effectiveness of implementing a quality management system in accordance with ISO 9001 in the context of technical regulations and testing standards.
