Translation of "Essieu à fusée extérieure " (French → English) :

fixed or adjustable minimum track width with one of the axles less than 1 150 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 1 150 mm. It must be possible to set the track width of the other axle in such a way that the outer edges of the narrower tyres do not go beyond the outer edges of the tyres of the other axle; where the two axles are fitted with rims and tyres of the same size, the fixed or adjustable track width of the two axles must be less than 1 150 mm;

fixed or adjustable minimum track width of less than 1 150 mm for the axles fitted with the widest tyres; since the axle fitted with the widest tyres is assumed to be adjusted to a maximum track width of 1 150 mm, the other axle must be capable of being adjusted in such a way that the outer edges of the narrowest tyres do not project beyond the outer edges of the tyres on the axle with the widest tyres; where both axles are equipped with wheels and tyres of the same size, the fixed or adjustable track width of both axles must be less than 1 150 mm;

This distance is increased to 300 mm in the case of the last axle where the radial distance of the lower edge of the outer valancing, Rv, does not exceed the dimensions of the radius of the tyres fitted to the wheels on that axle.

In the case of single axles, the lower edge of the outer valance may not be situated beyond the following distances and radii, as measured from the centre of the wheel, except at the lowest extremities that may be rounded (Figure 2 of Annex V).
