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 7.12.2 to 7.12.5.
7.14.                                         Alternative Procedures
7.14.1.                          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, for vehicles not equipped with a 'Variable Proportioning Brake System,', that the requirements of clause 7.13 are met at the lower 'GVMs'.
7.14.2.                          For vehicles not fitted with a 'Variable Proportioning Brake System', where clause 7.13.1.1 requires two tests at different masses, or where the provisions in clause 7.14.1 are utilised, the 'ERC' obtained by multiplying the 'ERC' determined from 7.13.3 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 4.1.9.
8.                                          ALTERNATIVE STANDARDS
8.1.                                    The technical requirements adopted by the United Nations – Economic Commission for Europe (UNECE) Regulation No. 13 – UNIFORM PROVISIONS CONCERNING THE APPROVAL OF VEHICLES OF CATEGORIES M, N AND O WITH REGARD TO BRAKING, incorporating any of the series of amendments from 10 to 11 for vehicles of category NA, or 5 to 11 for vehicles of category MD, ME, NB or NC, shall be deemed to be equivalent to the technical requirements of this standard, provided that, for hauling vehicles designed to be used in 'Road Train' combinations, the requirements of clause 7.12.6.2 are met, and provided that vehicles of category MD4, ME, NB or NC are fitted with an 'Antilock System', and provided that vehicles of category NA are fitted with an Electronic Stability Control System and a Brake Assist System, both meeting the requirements of APPENDIX 2 of this standard.
8.1.1.                              On vehicles to which the coupling of a trailer is authorised, the parking braking system of the towing vehicle need not be capable of holding the combination of vehicles stationary on a 12 per cent up or down-gradient, provided that the requirements of clause 4.3.5 are met.
8.1.2.                              In respect of Annexes 18 of UNECE Regulation No. 13/10 and Annex 18 to 21 of 13/11, vehicles will be deemed to meet the requirements of these annexes if compliance can be demonstrated during
