Certification mark for electric room heaters


The certification mark applies to household room heaters. Room heaters are heating appliances that heat the air in residential and working environments. They do not additionally provide hot water.

Basis of certification:

The test programme developed by TÜV SÜD is based on standards such as EN 60335-1 (Household and similar electrical appliances. Safety. Part 1: General requirements), EN 60335-2-30 (Part 2-30: Particular requirements for room heaters) and EN 62233 (Measurement methods for electromagnetic fields of household appliances and similar apparatus with regard to human exposure)

Key words of the certification mark:

  • IP X4
    The product certified by TÜV SÜD is protected against splash water. Items of equipment that may not be used in all environmental conditions are categorised by IP (ingress protection) rating. The statement “IP X4” means that the product is protected against water splashing against the enclosure.
  • Safety tested
    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.
  • Production monitored
    Periodic surveillance of the manufacturer 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 finished 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, certificate validity will expire and the TÜV SÜD certification mark may no longer be used.
