OECD AGR/CA/T(2000)23 MANDATORY CODE 4 TESTING WHEN 1150 mm TRACTOR WIDTH MAY BE EXCEEDED

During the Test Engineer's Conference held in 1999 in Prague different proposals were advanced to solve the problem of the tyre dimensions exceeding the minimum track width (1150 mm). In the meeting 3 proposals were suggested: 1) the range of tyre dimensions allowed in the type approval process may not guarantee adequate safety in some countries. Therefore, the testing procedure used may be inappropriate; 2) the validity of the test report may have to be restricted; 3) Code 4 testing may be appropriate provided it is amended to permit testing of tiltable front-mounted rollbars.
