The certification mark applies to LCD (liquid crystal display) and CRT (cathode ray tube) monitors.
The certification mark is based on the EN 60950-1 (Information technology equipment – Safety – Part 1: General requirements), EK1-ITB 2000, prEN 50279 and EN ISO 9241-307 standards and directives.
The tested products are in compliance with the requirements of the prEN 50279 standard “Visual display units – Measuring methods for low frequency electric and magnetic fields”.
The voluntary certification mark with the statement “Safety tested” is issued for products, indicating that the product was tested and certified by the independent third-party organisation of TÜV SÜD Product Service for conformity with the essential technical safety requirements.
Periodic surveillance of the manufacture of a product constitutes the basic premise for certification which includes the award of a certification mark. Certification always requires product testing and regular factory inspections.
As a third-party expert organisation, TÜV SÜD verifies that the manufacturer is able to maintain consistent quality in line with the requirements throughout high-volume production and has established the necessary quality system, including incoming goods inspections, lists of materials and final product check.
In addition, calibration of the necessary measuring and monitoring equipment must be ensured. Surveillance and/or monitoring covers the testing of safety-critical components and other materials used. If unauthorised changes are made to the product, the certificate will be withdrawn and the TÜV SÜD certification mark may no longer be used.
