defined in the Consolidated Resolution on the Construction of Vehicles (R.E.3.), document ECE/TRANS/WP.29/78/Rev.2, para. 2

        [2]  An axle group shall be treated as a single axle and dual wheels shall be treated as a single wheel.
         [3]  As declared by the vehicle manufacturer.
         [4]  The distinguish numbers of the Contracting Parties to the 1958 Agreement are reproduced in
       Annex 3 to Consolidated Resolution on the Construction of Vehicles (R.E.3),
       document TRANS/WP.29/78/Rev.2.
         [5]  The Authority, which is to grant approval, shall have the right to check the service braking system by additional vehicle test procedures.
        [6] By agreement with the Technical Service, state of charge assessment will not be required for vehicles, which have an on-board energy source for charging the traction batteries and the means for regulating their state of charge.
         [7]  Until uniform test procedures have been agreed, the manufacturer shall provide the Technical Service with an analysis of potential failures within the control transmission and their effects. This information shall be subject to discussion and agreement between the Technical Service and the vehicle manufacturer.
         [8]  At the time of type approval, compliance with this requirement shall be confirmed by the vehicle manufacturer.
         [9]  During a "selective braking" event, the function may change to "automatically commanded braking".
         *  At the request of (an) applicant(s) for Regulation No. 90 approval, the information shall be provided by the Type Approval Authority as contained in Appendix 1 to this annex. However, this information shall not be provided for purposes other than Regulation No. 90 approvals.
         1  Distinguishing number of the country which has granted/extended/refused/withdrawn approval (see provisions in the Regulation).
         2  Strike out what does not apply.
         [13]  This number is given merely as an example.
         [14]  The manufacturer shall provide the Technical Service with the family of braking curves permitted by the automatic control strategy. These curves may be verified by the Technical Service.
         [15]  This corresponds to a stopping distance of 0.1 v + 0.0080 v2 and a mean fully developed deceleration of 4.82 m/s2.
         [16]  The initial energy level shall be stated in the approval document.
         [17]  "Adhesion utilisation curves" of a vehicle means curves showing, for specified load conditions, the adhesion utilized by each axle i plotted against the braking rate of the vehicle.
         [18]  The provisions of paragraph 3.1. do not affect the requirements of Annex 3 to this Regulation relating to the braking performance. However, if, in tests made under the provisions of paragraph 3.1., braking performances are obtained which are higher than those prescribed in Annex 3, the provisions relating to the adhesion utilization curves shall be applied within the areas of diagram 1 of this annex defined by the straight lines k = 0.8
