Technical regulation and scope of the EN 1653 standard
The European standard EN 1653 defines strict technical requirements for the component composition, as well as limit deviations for geometric parameters (shapes and dimensions) for flat-rolled products — plates, sheets, and circles made of pure copper and specialized copper alloys. This regulatory document serves as a baseline for the design and manufacture of pressure-bearing equipment, including steam boilers, industrial heat exchangers, pressure vessels, and hot water storage tanks.
EV Group China ensures the supply of metal products that fully comply with EN 1653 specifications, including regulated quality control procedures, sampling methods for laboratory testing, and compliance with conditions for the safe transportation and storage of products.
Key aspects of quality control according to EN 1653
- Chemical composition of the material, which determines corrosion resistance and thermal conductivity.
- Tolerances for thickness, flatness, and diametrical dimensions of sheet and circular rolled products.
- Test protocols for mechanical properties at operating temperatures.
- Standardized requirements for surface cleanliness and the absence of defects of metallurgical origin.
