Continuous surveillance of the production processes of a product constitutes the basic premise for certification that includes the award of a certification mark. Certification including the award of a certification mark always requires product tests and 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. Depending on the certification mark, the experts also take samples from ongoing production for further laboratory testing. In the case of unauthorised changes, the certificate will become invalid and the TÜV SÜD certification mark may no longer be used.
