On the Possibility of Harmonization of GOST 7512 Standard with ISO 17636-1 International Standard

The article discusses the feasibility of developing and introducing a national standard harmonized with the international standard ISO 17636-1 with the subsequent cancellation of GOST 7512 in order to bring closer the requirements for the radiographic inspection technology. Ways of approximation of national and international standards are proposed, which will
ensure a smooth transition to common requirements.
