I.4.1.2. Vehicles with a manually operated gearbox

According to Directive 70/156/EEC.`

The vehicle shall have the parking brake released and the gearbox in neutral.

In the case of vehicles with manual or semi-automatic transmission gearboxes the test shall be carried out with the gear lever in the "neutral" position and with the clutch engaged.

In the case of manual gear-boxes, it shall be possible to lock the gear-shift lever in the following positions only: reverse plus neutral, or reverse only.

Manual transmission

Manual-shift or semi-automatic gearbox

Gear to be used in the case of a manual gearbox

Manually-operated, non-automatic gearbox.

In the latter case the procedure for manual gearboxes shall be applied.

Automatic transmission equipped with manual override.

Automatic gearbox fitted with manual selector.

manual transmissions to be in gear with the clutch disengaged, except in the first idle mode.

Approval granted to a vehicle type with a manual transmission may under the following conditions be extended to vehicle types with automatic or continuously variable transmissions:

the vehicle type must have a reference mass within ± 5 % of the reference mass of the vehicle type with the manual transmission;

the vehicle type must have a reference mass within ± 5 % of the reference mass of the vehicle type with the manual transmission;

The manufacturer's instructions for driving in town, or in their absence instructions applicable to manual gearboxes, shall be followed.

Manual transmission vehicles must have the clutch engaged and must not change gears from the previous mode.

For manual transmissions, the operator must release the accelerator pedal during each gear change and complete the change in the minimum amount of time.

If an acceleration cannot be carried out in the prescribed time, the gear selector is operated in accordance with requirements for manual-shift gearboxes.

In the case of vehicles with manual or semi-automatic transmission gearboxes the test shall be carried out with the gear lever in the 'neutral' position and with the clutch engaged.

The limit given in 3.1.1 is brought to ±50 % for one second when starting and, for vehicles with manual transmission, for two seconds during gear changes.

The limit given in 3.1.1 is brought to ±50 % for one second when starting and, for vehicles with manual transmission, for two seconds during gear changes.

If the vehicle is fitted with an automatic gearbox which has no manual selector, it must be tested at different approach speeds:

In the case of vehicles with manually-operated or semi-automatic-shift gearboxes the test must be carried out with the gear lever in the 'neutral' position and with the clutch engaged.

Vehicles in categories M1 and N1 equipped with a manually operated gearbox having not more than four forward gear ratios must be tested in second gear.

If the vehicle is fitted with a manually-operated auxiliary gearbox or a multiple ratio drive axle, the position corresponding to normal town driving must be used.

Vehicles in these categories equipped with a manually operated gearbox having more than four forward gear ratios must be tested in second and third gears successively.

In the case of test vehicles equipped with manual transmission, the transmission must be shifted according to the procedures recommended by the manufacturer, subject to the agreement of the technical service responsible for the tests.

In the case of a vehicle with a manual gearbox or an automatic transmission where the gearbox can be disengaged manually, the highest gear, consistent with attaining the initial test speed, must be engaged during the stops.

For those modes which decelerate to zero, manual transmission clutches must be depressed when the speed drops below 24,1 km/h, when engine roughness is evident, or when engine stalling is imminent.

In the case of a vehicle with a manual gearbox or an automatic transmission where the gearbox can be disengaged manually, the tests must be carried out with the gearbox inoperative and/or the engine disconnected by clutch disengagement or otherwise.

If the vehicle is equipped with an automatic transmission which has no manual override, it must be tested at different approach speeds, namely 30, 40 and 50 km/h, or at three-quarters of maximum road speed if this value is lower.

Vehicles with a manually operated gearbox

5.2.2.4.3.3.1.Manually-operated, non-automatic gearbox

In the latter case the procedure for manual gearboxes applies.

have the same type of gearbox (manual, automatic, etc.);

the manufacturer's instructions for driving in town, or in their absence instructions applicable to manual gearboxes, must be followed.

In the case of manual gearboxes it must be possible to lock the gearshift lever in reverse only;

In the case of vehicles with manually-operated or semi-automatic-shift gearboxes the test must be carried out with the gear lever in the "neutral" position and with the clutch engaged.

If the vehicle is fitted with a manual gear change, the gear ratio used is the highest recommended by the manufacturer for driving at each of the test speeds.

If any part of a gear lever or handbrake lies above the H point level that lever will have to be considered as if the whole of it were above the H point level.

If the vehicle is equipped with an automatic transmission which has no manual override, it must be tested at different approach speeds, namely 30, 40, and 50 km/h, or at three-quarters of maximum road speed if this value is lower.

-for vehicles in category 5.2.2.1.1., equipped with a manually operated gear box having more than four forward gears and with an engine developing a maximum power exceeding 140 kW/t and whose permissible maximum power/maximum mass ratio exceeds 75 kW/t, the limit values are increased by 1 dB (A) if the speed at which the rear of the vehicle passes the line BB& prime; (Figure 1) in third gear is greater than 61 km/h.
