Another focus beside to product quality is product safety, which TÜV SÜD determines by performing safety-related tests on the series-manufactured products. The voluntary certification mark with the statement "Safety tested" is issued, indicating that the product was tested and certified for conformity with the essential technical safety requirements.
The certification criteria vary depending on the products in question. While the focus in the case of a hair dryer, for example, is on electrical safety, the focus in the case of a car jack is on the mechanical characteristics. Certification is based on product-specific standards and test programs, which are identified on the relevant certificate.
