Welcome into the World of Westlake
TÜV SÜD is one of the tyre testing leaders. It is the largest independent institute for tyre and wheel technologies in Europe. As a certified test lab for tyre properties, it provides the full scope of tyre tests according to standards, regulations and customers-specified requirements.
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 TÜV SÜD certification mark, the tyre to be tested must comply with certain threshold values in the tests. The threshold values are based on either a reference condition or fixed reference values. The tyre must also fulfill all minimum requirements set forth in Regulations ECE R30 and ECE R117.
- Manufacturing quality:
Annual inspection of manufacturing facilities and evaluation of general production conditions
- Product quality:
Tyre performance tests in road and rig tests
(individual and comparative tests) – annual product (COP-tests) or manufacturing inspections are required
