The ISO9000 quality management standard is based on European and American manufacturing and can be applied to various industries. However, due to the failure to solve the problem of transforming according to the characteristics of the industry in the specific implementation, it lacks operability and industry substantive guidance. It has caused difficulties for many construction enterprises to effectively implement the ISO9000 family of quality management standards. The basis for solving this problem is to improve the quality code of conduct in the engineering construction industry, and thereby promote the improvement of the quality management system of enterprises.

This requires the support of a quality management specification that is more industry-specific than the ISO9000 family of international quality management standards, resulting in the GB50430 standard, which is the localization and industrialization of the ISO9000 standard.

GB/T50430 comprehensively covers GB/T9001-2000 "Quality Management System Requirements". The main difference is that the industry is different and the content is different. To put it bluntly, it's just a name change.
