We’ve developed, tested, approved, and certified our snow chain alternative in close cooperation with leading car manufacturers and different nationally and internationally accredited certification bodies.
AutoSocks for cars have been certified and monitored by the TÜV SÜD safety and performance standard PPP 53219 since 2001. They are legal for cars both with and without trailers (vehicle classes M1, N1, O1 & O2).
Since 2006, AutoSocks for trucks and busses have also been certified and monitored by the PPP 53283 TÜV SÜD safety and performance standard. This makes them legal for vehicles from 3,500 to 7,700 lbs., both with and without trailers (vehicle classes M2, M3, N2, N3, O3, O4). They have been approved as a “Winter Protective Overall” device and “Snow Chain Equivalent”.
They were the first product to appear in the new, non-metal based product category, fully certified alongside traditional metal-based snow chains.
In 2008, AutoSock met the requirements of the ÖNORM V 5121.
Today AutoSock is also approved directly by car manufacturers themselves, including BMW Group, Citroën, Fiat Group, Hyundai, Jaguar, Land Rover, Mitsubishi, Nissan, Peugeot, Seat, Suzuki, Daihatsu, Volvo, VW, and many more of the world’s top manufacturers.
The following chart is the result of an extensive cross-testing campaign, performed by an independent, accredited certification body in 2011:
