Technical Standard EN 10244-4: Tin coatings on steel wire
This standard establishes strict industry requirements for the characteristics and control methodology of tin coatings applied to round and shaped steel wire. EV Group China documentation confirms compliance with these standards to ensure corrosion protection and improve the solderability of metal products.
The standard details the following:
- Regulations for the mass of the tin layer for various wire diameters.
- Test methods for adhesion and coating uniformity.
- Requirements for surface preparation quality prior to the tinning process.
EV Group China specialists use these specifications to control the quality of wire supplies intended for operation in environments requiring increased chemical resistance and precise adherence to protective layer thickness tolerances.
