What is EN 50558

The EN50558 standard is a technical specification developed by the European Committee for Electrotechnical Standardization (CENELEC). It pertains to power supply cords and cord sets used in household appliances, audio/video equipment, and information technology devices. This article aims to explain the key aspects of EN50558 in an easy-to-understand manner.

Standard requirements

EN50558 sets forth various requirements that power supply cords and cord sets need to meet. These include parameters like rated voltage, maximum temperature, and insulation resistance. Compliance with these requirements ensures the safety, reliability, and compatibility of cords across different appliances and devices.

Testing and certification

To verify compliance with EN50558, power supply cords and cord sets undergo rigorous testing procedures. This testing typically includes measurements of electrical properties, mechanical strength, and resistance to environmental factors like high temperature and humidity. Only cords that pass these tests are granted certification to be marketed and sold.

Benefits and importance

EN50558 brings several benefits to manufacturers, consumers, and regulatory bodies. First and foremost, it fosters safety by ensuring that cords are capable of withstanding the expected electrical load and environmental conditions. Additionally, the standard facilitates international trade, as products certified under EN50558 can be readily accepted in different markets.

For consumers, the standard provides peace of mind knowing that the cords they use are reliable and safe. It also enables them to easily replace or interchange cords between different appliances without compatibility issues. Moreover, compliance with EN50558 allows regulatory bodies to enforce uniform safety standards and protect the interests of end-users.

Overall, the EN50558 standard plays a crucial role in ensuring the quality and safety of power supply cords and cord sets used in various applications. Its technical requirements, testing procedures, and certification process contribute to harmonization, reliability, and consumer protection in the electrical industry.
