Abstract
  • 1. Rationale 1.1 During the 2000 Annual Meeting held in Paris, an Italian proposal was presented aiming to solve the problem of tyre dimensions not meeting the minimum track width requirement (1150 mm) [AGR/CA/T(2000)23]. This proposal intended to harmonise within Code 6 the first sentence of point 2.1.2 (Field of application) and point 3.1.2.2 (Rules and Directions, Preparation for the preliminary tests). The same modification should be introduced in Code 7. 1.2 At the beginning of 2000 the ISO issued the Draft International Standards ISO/DIS 12003-1 and 12003-2. These draft standards are nearly equivalent to OECD Codes 6 and 7, but a significant difference is introduced in the field of application (defined as \"Scope\" in the ISO Drafts), as follows: o Code 6 and 7, point 2.1.2 (\"Blue Codes\", pages 226 and 302): \"fixed or adjustable minimum track width with one of the axles less than 1150 mm fitted with tyres of a larger size. It is assumed that the axle mounted with the wider tyres is set at a track width of not more than 1150 mm.\" ... o ISO/DIS 12003-1 and -2: \"fixed or adjustable minimum track width with one of the two axles less than 1150 mm, when fitted with widest tyres. The overall width of the other axle may not be wider than the one of the before mentioned axle;\" ... Comparing these two sentences, it can be observed that the word \"larger\" used in the OECD Codes is not strictly referred to a specific geometrical parameter of the tyre. In fact, it can be applied to the diameter or to the cross-section of the tyre. On the other hand, the ISO draft introduces the word \"widest\" being this time strictly referred to cross-section. In the light of this, many tractor models presently put in the \"narrow-track\" category following the OECD Codes, should be excluded. Be that as it may, it is well known that narrow tractors differ throughout the world depending on the type of agricultural mechanisation. As a consequence, it is necessary to take into account the possible contribution of all OECD members in order to collect the widest possible data set and find the best solution. (literal)
