be de-activated at the latest when the deceleration has fallen below 0.7 m/s² 8.
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 fulfilled8:
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. Subject to the requirements of paragraphs 12.1. to 12.2., any vehicle fitted with an ESC system complying with the definition of paragraph 2.25. shall meet the equipment, performance and test requirements contained in Part A of Annex 9 to this Regulation.
5.2.24.1. As an alternative to the requirement of paragraph 5.2.24., vehicles of categories M1 and N1 with a mass in running order > 1,735 kg may be equipped with a vehicle stability function which includes roll-over control and directional control and meets the technical requirements of Annex 21 to Regulation No. 13.
5.2.25. 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 Administrative Department which approved the vehicle type. That department 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 Competent Authority issuing the
