OECD AGR/CA/T(2000)19 PROPOSAL FOR AMENDING THE LATERAL STABILITY TEST IN CODE 6

Based on the experience gained when testing lateral stability according to Code 6 (narrow-track tractors with front-mounted ROPS), the Italian Testing Stations reported to the Prague Test Engineer's Conference the following observations: o the measurement of the stability limit angle using different methods for the same tractor (= Tilting platform, Wheel lifting, Horizontal displacement of the protective frame) result in differences up to 12°; o some tractors that pass the 38° test with the method of direct lifting of one axle, do not pass with such method(s) as using a tilting platform. Since different methods can bring different results in static stability assessment of the tractor, the Test Engineer's Conference concluded that a new wording of the Code was perhaps necessary. The draft Summary Record contains a proposal for amending the lateral stability test (first line of paragraph 3.1.3.2 page 33).
