Seek popular science and introductions to the US standard system

The American standard system primarily refers to the American industrial standards widely used internationally, including ASME, ASTM, API, etc. 1. ASME (American Society of Mechanical Engineers): ASME is a globally influential association of mechanical engineers that is responsible for developing and issuing standards and specifications related to various engineering materials, mechanical manufacturing, and inspection, such as the \"Boiler and Pressure Vessel Code\" and the \"Piping Code\". 2. ASTM (American Society for Testing and Materials): ASTM is an organization dedicated to the development and publication of international standards. Its standards cover a wide range of areas such as materials, products, systems, and services, including standards for steel materials, as well as standards for petroleum products, lubricants, and paraffins. 3. API (American Petroleum Institute): API is primarily responsible for developing and issuing various standards in the fields of petroleum, natural gas, and chemicals, such as the \"Standards for Petroleum Equipment and Materials\" and the \"Standards for Petroleum Drilling and Production Equipment\". The American standard system is widely used worldwide in areas such as engineering construction, material testing, product manufacturing, and services. Adopting American standards helps ensure the quality and safety of projects, thereby enhancing their international competitiveness. At the same time, using American standards is also a basic requirement for many foreign projects, especially in industries such as petrochemicals and energy. .
