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 category MD, ME, NB and NC vehicles, to be equivalent to all technical requirements of this standard, except (where applicable) for the requirements of:
             1.             Clause 5.1.9 (see clause 9.2.3 below), in the case of category ME vehicles with a 'GVM' exceeding 12 tonnes and category NC 'Prime Movers';
             2.             Clauses 5.3.5 to 5.3.7, in the case of vehicles equipped to tow a trailer which uses air at positive pressure;
             3.             Clause 5.8.1.1, in the case of vehicles designed to be used in 'B‑Double' and/or 'Road Train' combinations; and
             4.             Clauses 5.8.2 and 8.12.6(b), in the case of vehicles designed to be used in 'Road Train' combinations.
     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.
     1.                               The requirements of Annex 21 of the United Nations Regulation No. 13, incorporating the 11 series of amendments are not applicable for category ME vehicles with a 'GVM' exceeding 12 tonnes and category NC 'Prime Movers', not otherwise deemed according to clause 3.9 above to comply with this standard.  These vehicles must instead meet the applicable requirements of clauses 5.1.8 and 5.1.9 of this standard.
     2.                               An additional hand 'Control' may be fitted to enable the 'Service Brake System' of a towed trailer, to be operated independently of the 'Service Brake System' and/or 'Secondary Brake System' of the towing vehicle.
     3.                               On vehicles equipped to tow a trailer with a compressed-air braking system, 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 the operation of the parking brake system causes the pressure in the 'SUPPLY LINE 35/…' to drop below 35 kPa – as is required by the reference to clause 5.3.5 in clause 9.2(b) above.
