Monitoring of international standards in the field of ISO/TC 71 “Concrete, reinforced concrete, prestressed reinforced concrete”

Introduction. The article is based on the results of monitoring the regulatory framework of international standards in the field of ISO/TC 71 “Concrete, reinforced concrete, prestressed reinforced concrete”. Monitoring and analysis of newly developed and updated international standards is done to identify gaps in the domestic regulatory framework, to find duplicate or contradict regulatory documents, to establish relationships with regulatory documents related to adjacent areas, to monitor and analyze existing regulatory technical documents for the sufficiency of requirements in the field of the committee’s activities, to prepare proposals for the development of mandatory construction norms.

The aim is to analyze and compare the international and Russian regulatory and technical base for its timely updating and elimination of emerging duplications and contradictions, to increase the level of harmonization of Russian and international norms and standards in the field of construction of buildings and structures, from the point of view of introducing progressive domestic developments into the regulatory framework, to develop proposals for amendments to regulatory technical documents and development of new regulatory documents in this area.

Materials and methods. International ISO standards were selected as the material, and European and American standards were compared with their Russian counterparts for further analysis.

Results. The article provides selective monitoring, analysis and comparison of ISO standards and the Russian regulatory and technical framework for its timely updating and elimination of duplications and contradictions, increasing the level of harmonization of Russian and international norms and standards in the field of construction of buildings and structures ISO/TC 71 “Concrete, reinforced concrete, prestressed reinforced concrete”. Nine international ISO standards have been analyzed with a view to possible harmonization with Russian national standards.

Conclusions. Based on the results of monitoring:

1. 9 ISO/TC 71 standards “Concrete, reinforced concrete, prestressed reinforced concrete” are considered. The systematization of the current ISO standards related to the field of activity of ISO/TC 71 “Concrete, reinforced concrete, prestressed reinforced concrete” has been carried out.

2. The closest analogues of normative technical and methodological documents in the national standardization system for the analyzed ISO standards are identified and analyzed.

3. Proposals have been prepared for the development of new and updating previously approved codes of rules, building codes and regulations.
