The international steel product quality standard systems mainly include the following aspects:
I. International Standards
ISO Standards: International standards for steel products formulated by the International Organization for Standardization (ISO). ISO standards are widely recognized and applied globally, serving as an important basis for assessing the quality of steel products. For example, ISO 9001 is an international standard for quality management systems, applicable to quality management in steel enterprises, ensuring that products and services meet customer needs and requirements.
IEC Standards: Although the International Electrotechnical Commission (IEC) primarily focuses on standardizing the electrical field, some of its standards may also relate to the electrical performance of steel products or related technological applications.
II. Regional or National Standards
European Standards (CEN Standards): Formulated by the European Committee for Standardization (CEN), these standards apply to steel products in Europe. European standards emphasize product quality and safety, as well as compliance with specific needs of the European market.
American Standards (AISI/ASTM Standards): Formulated by the American Iron and Steel Institute (AISI) and the American Society for Testing and Materials (ASTM), these standards provide detailed specifications for the chemical composition, mechanical properties, dimensional accuracy, and other aspects of steel products, applicable to the United States and some international markets.
Chinese Standards (GB/T Standards): Formulated by the Standardization Administration of China, these standards apply to steel products in the Chinese market. Chinese standards cover various types, specifications, and applications of steel products, ensuring that product quality complies with Chinese laws, regulations, and market demands.
Other National Standards: Such as British Standards (BSI Standards), Australian Standards (Standards Australia Standards), Indian Standards (BIS Standards), etc. These standards are formulated by the standardization agencies of respective countries and apply to the steel markets of those countries.
III. Industry Standards or Professional Standards
Metallurgical Product Standards (YB): Formulated by the China Iron and Steel Association or related industry associations, these standards apply to steel products in the Chinese metallurgical industry. These standards may focus more on specific types or applications of steel products, such as hot-rolled steel plates and cold-rolled thin steel plates.
Other Industry Standards: Industry organizations such as the International Iron and Steel Institute (IISI) may also formulate some industry standards or guiding principles to promote sustainable development and technological innovation in the global steel industry.
