The Type Approval mark of TÜV Rheinland is usually awarded for components that are not ready for use and occasionally also for finished products.
The components (e. g. switches, connectors, power supplies, capacitors, relays) are by themselves not ready for use, but intended to be incorporated into finished products.
The tests focus on the safety of each component. The Type Approval is a voluntary test, which helps TÜV Rheinland to confirm that a product meets the relevant safety requirements.
After type examination the manufacture of products, which have received this test mark, is regularly monitored. The certification is valid as long as the test specifications are up to date and the certificate has not been terminated, neither by the customer nor by TÜV Rheinland. The validity of the certificate expires if changes are made to the product.
Certified products may be labelled with a test mark.
