of part of the service braking system by "selective braking" shall not generate the signal mentioned above.[6]
              5.2.22.4. Electric regenerative braking systems as defined in paragraph 2.17. of this Regulation, which produce a retarding force upon release of the accelerator control, shall generate the signal mentioned above according to the following provisions:

Vehicle decelerations      Signal generation
≤ 0.7 m/s²                 The signal shall not be generated
> 0.7 m/s² and ≤ 1.3 m/s²  The signal may be generated
> 1.3 m/s²                 The signal shall be generated

              In all cases the signal shall be de-activated at the latest when the deceleration has fallen below 0.7 m/s².5
5.2.23. When a vehicle is equipped with the means to indicate emergency braking, activation and de-activation of the emergency braking signal shall only be generated by the application of the service braking system when the following conditions are fulfilled: 5
5.2.23.1. The signal shall not be activated when the vehicle deceleration is below 6 m/s² but it may be generated at any deceleration at or above this value, the actual value being defined by the vehicle manufacturer.
 The signal shall be de-activated at the latest when the deceleration has fallen below 2.5 m/s².
5.2.23.2. The following conditions may also be used:
(a) The signal may be generated from a prediction of the vehicle deceleration resulting from the braking demand respecting the activation and de-activation thresholds defined in paragraph 5.2.23.1. above;
 or
(b) The signal may be activated at a speed above 50 km/h when the antilock system is fully cycling (as defined in paragraph 2. of Annex 6).
 The signal shall be deactivated when the antilock system is no longer fully cycling.
5.2.24. Power-driven vehicles of category M1 and N1 equipped with temporary-use spare wheels/tyres shall satisfy the relevant technical requirements of Annex 3 to Regulation No. 64.
              6. Tests
 Braking tests which the vehicles submitted for approval are required to undergo, and the braking performance required, are described in Annex 3 to this Regulation.
              7.  Modification of vehicle type or braking system and extension of approval
7.1. Every modification of the vehicle type or of its braking system shall be notified to the Type Approval Authority which approved the vehicle type. That Authority may then either:
7.1.1. Consider that the modifications made are unlikely to have an appreciable adverse effect and that in any case the vehicle still meets the requirements; or
7.1.2. Require a further report from the Technical Service responsible for carrying out the tests.
7.2. Notice of confirmation, extension, or refusal of approval shall be communicated by the procedure specified in paragraph 4.3. above, to the Parties to the Agreement which apply this Regulation.
7.3. The Type Approval Authority issuing the extension
