Certification mark for LCD monitors

The EN ISO 9241 “Ergonomics of human-system interaction” Standard describes requirements for the work environment and for hardware and software. Part 307 regulates “Analysis and compliance test methods for electronic visual displays”. The objective of the standard is to prevent health problems in computer work.

The tested LCD monitors are flicker-free, help to protect users’ eyes and effectively reduce eye strain.

The “Safety tested” TÜV SÜD mark is a voluntary product certification mark, 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 that includes the award of a certification mark. Certification always requires product testing and regular factory inspections.

As a third-party expert organisation, TÜV SÜD Product Service 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 testing.

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 If unauthorised changes are made to the product, the certificate will be withdrawn and the TÜV SÜD certification mark may no longer be used.
