procedure described in Annex 3 to this Regulation.
9.2. Test 2: For activation of BAS
 The vehicle shall be driven in a straight line at the test speed specified in paragraph 7.4. of this Regulation. The driver shall apply the brake pedal quickly according to Figure 2, simulating emergency braking so that BAS is activated and ABS is fully cycling.
 In order to activate BAS the brake pedal shall be applied as specified by the car manufacturer. The manufacturer shall notify the Technical Service of the required brake pedal input at the time of submission of the application for type-approval. It shall be demonstrated to the satisfaction of the Technical Service that the BAS activates under the conditions specified by the manufacturer in accordance with paragraph 16.1.1. or 16.1.2. of Annex 1.
 After t = t0 + 0.8 s and until the vehicle has slowed down to a speed of 15 km/h, the brake pedal force shall be maintained in a corridor between FABS, upper and FABS, lower, where FABS, upper is 0.7 FABS and FABS, lower is 0.5 FABS.
 The requirements are also considered to be met if, after t = t0 + 0.8 s, the pedal force falls below FABS, lower provided the requirement of paragraph 9.3. is fulfilled.
9.3. Data evaluation
 The presence of BAS 'B' is demonstrated if a mean deceleration (aBAS) of at least 0.85 ∙ aABS is maintained from the time when t = t0 + 0.8 s to the time when the vehicle speed has been reduced to 15 km/h.

              10.  Modification of vehicle type or BAS and extension of approval
10.1. Every modification to an existing vehicle type shall be notified to the Type Approval Authority which approved the vehicle type.
 The Authority shall then either:
(a) Decide, in consultation with the manufacturer, that a new type-approval is to be granted; or
(b) Apply the procedure contained in paragraph 10.1.1. (Revision) and, if  applicable, the procedure contained in paragraph 10.1.2. (Extension).
10.1.1. Revision
When particulars recorded in the information documents have changed and the Type Approval Authority considers that the modifications made are unlikely to have appreciable adverse effects and that in any case the foot controls still meet the requirements, the modification shall be designated a "revision".
In such a case, the Type Approval Authority shall issue the revised pages of the information documents as necessary, marking each revised page to show clearly the nature of the modification and the date of re-issue. A consolidated, updated version of the information documents, accompanied by a detailed description of the modification, shall be deemed to meet this requirement.
10.1.2. Extension
The
