(c) the concept of the suspensions (steel, air or hydraulic suspension); (d) the following technical features: (i) the capability or not for the chassis to be extendible; (ii) the deck height (normal, low loader, semi-low loader etc.); (e) in the case of multi-stage built vehicles, the manufacturer and the type of the previous stage vehicle. 6.3. Versions 6.3.1. A within a variant shall group the vehicles that have the following ‘version’ features in common: (a) the technically permissible maximum laden mass; (b) the subdivisions or combination of subdivisions referred to in points 3.2 and 3.3 of Annex I to Directive 96/53/EC into which the axle spacing between two consecutive axles forming a group belongs; (c) the definition of the axles in the following respects: (i) lift axles (number and position); (ii) loadable axles (number and position); (iii) steered axle (number and position). 7. Common requirements for all vehicle categories 7.1. When a vehicle falls into several categories because of its maximum mass or the number of seating positions or both, the manufacturer may select to use the criteria of one or the other vehicle category for the definition of the variants and the versions. 7.1.1. Examples: (a) a vehicle may be type-approved as N1 (3,5 tonnes) and N2 (4,2 tonnes) ‘A’ in relation to its maximum mass. In such a case, the parameters mentioned in category N1 may be used also for the vehicle that falls into category N2 (or vice-versa); (b) a vehicle may be type-approved as M1 and M2 in relation to the number ‘B’ of seating positions (7 + 1 or 10 + 1), the parameters mentioned in category
