EN 10120 is a European standard that specifies the technical delivery conditions for steel plates and strips used in the manufacture of pressure vessels. It outlines the requirements for the chemical composition, mechanical properties, and testing methods to ensure the safety and reliability of these materials under pressure. The standard is essential for industries that produce equipment like boilers and storage tanks, where safety is critical. By adhering to EN 10120, manufacturers can ensure that their products meet regulatory requirements and perform effectively in demanding environments.
