Proposed requirement for the mounting height of couplings on tractors under chapter 5 of UN Regulation No. 55.
3.6 Vehicle approval according to Chapter 5 possible?
A vehicle approval for category T vehicle is possible. As R and S categories are not yet defined in R.E.3, vehicle approvals are currently not possible. As soon as those definitions are adopted, the scope of R 55 shall be extended accordingly. Mr Schauer will add the requirement for the mounting height of couplings on tractors to chapter 5 (already done, see TFAC-03-14).
