The certification mark applies to normal tyres (summer), M&S-, snow- (Three Peak Mountain Snow Flake “3PMSF”) and Nordic snow tyres for motor vehicles.
The certification mark is awarded within the framework of voluntary testing and certification. The test procedure was developed by TÜV SÜD Product Service. To be awarded the certification mark, the tyre to be tested must neither fall below nor exceed certain threshold values in the test.
It also must meet certain minimum performance requirements compared to the average results of selected benchmarks. When evaluating the tyre against the competitive set, the result achieved by the tested tyre will be placed in relation to the mean value of the collective group. The quotient is the percentage value of the test tyre in the respective test. The mean value of the competitors is always used as the basis, i.e. as 100 per cent. Given this, the tyre will achieve a percentage above or below 100 per cent depending on its performance. Calculation of the percentage is such that performance better than that of the collective group will always achieve a value of > 100 percent while poorer performance will be rated at a value < 100 percent.
Periodic surveillance and/or monitoring 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 If unauthorised changes are made to the product, the certificate will become invalid (withdrawn) and the TÜV SÜD certification mark may no longer be used.
TÜV SÜD Product Service tests the shoe lasts that form the basis of shoe manufacturing for various criteria, including length and heel width. Subsequently, the interior dimensions of the prototype shoes manufactured on the basis of the lasts are verified.
At regular intervals certified products will be bought in the market to perform spot checks and verify that the product is still meeting the requirements defined on the certification mark.
For the statement "Tested for harmful substances", TÜV SÜD tested the product for hazardous substances. The test is based on legal requirements, specific national requirements and own specifications.
