E.T.R.T.O.  Standards are  specifications  of international interest,  including future developments,  approved in accordance with the Organisation's Constitution and Rules of Procedure. Although not exclusive, they are based on sound knowledge and experience and will enable users to obtain good services from their tyres/rims/valves, but as they give only general advice, they cannot take into account special conditions of use and every different type of vehicle.

In consequence, the application of E.T.R.T.O. Standards does not absolve the user of them from any product liability responsibilities or legal obligations that may be required and which may vary from country to country. Further, E.T.R.T.O. does not accept any responsibility for the infringement of patents relating to the data for tyres/rims/valves specified as E.T.R.T.O. Standards in this publication.
