5 evenly spaced steps until an 'ERC' of not less than 0.45 is reached.
     3.                           The 'Service Brake System' 'ERC' must be determined according to either of the following:

                 where:

                 V is the initial speed in km/h
                 S is the 'Stopping Distance' in metres
                 T is the 'Stopping Time' in seconds
                 TR is the response time measured from the time the 'Control' leaves
                  the 'Initial Brake Control Location' until the energy level at the
                  least favoured actuator reaches 65 per cent of 'Average Operating
                  Pressure' and is measured in a separate test in accordance with
                  clause 8.12.2 to 8.12.5.
 1.                                 Alternative procedures
     1.                           Where a vehicle design has a number of configurations such that the 'GVMs' of these configurations span more than one vehicle category, testing at the higher of these 'GVMs' will be deemed to demonstrate compliance at the lower of these 'GVMs' provided that any differences in 'Lightly Loaded Test Mass' are fully tested and that the requirements of clause 5.1.14 (where applicable) are also met at the lower 'GVMs'.
     2.                           Where clause 8.13.1 requires two tests at different masses, or where the provisions in clause 8.14.1 are utilised, the 'ERC' obtained by multiplying the 'ERC' determined from 8.13.3 at the tested mass, by the tested mass in tonnes, and then dividing that figure by the alternative mass in tonnes, will be deemed to be the 'ERC' for the alternative mass for the purposes of clause 5.1.14.

 1.                                           ALTERNATIVE STANDARDS
     1.                                     The technical requirements of the United Nations Regulation No. 13 – UNIFORM PROVISIONS CONCERNING THE APPROVAL OF VEHICLES OF CATEGORIES M, N AND O WITH REGARD TO BRAKING, incorporating the 11 series of amendments, are deemed for category NA vehicles, to be equivalent to the technical requirements of this standard.
         1.                               Vehicles will be deemed, for the purposes of this national standard, to meet the technical requirements of Annex 18 of the United Nations Regulation No. 13, incorporating the 11 series of amendments, if compliance can be demonstrated as part of an application for Type Approval and/or during a Conformity of Production assessment.
         2.                               The requirements of Annex 21 of the United Nations Regulation No. 13, incorporating the 11 series of amendments are not applicable for the purposes of certification of category NA vehicles to this national standard.  Vehicle stability requirements for category NA vehicles are instead specified through the Australian Design Rule 88/…1 – Electronic Stability Control (ESC) Systems.
     2.                                     The technical requirements of the United Nations Regulation No. 13 – UNIFORM PROVISIONS CONCERNING THE APPROVAL OF VEHICLES OF CATEGORIES M, N AND O WITH REGARD TO BRAKING, incorporating the 11 series of amendments, including as varied by clauses 9.2.3 and 9.2.4 below, are deemed for
