ADDITIONAL REQUIREMENTS CONCERNING COMPLETE OR COMPLETED EX/II OR EX/III VEHICLES INTENDED FOR THE CARRIAGE OF EXPLOSIVE SUBSTANCES AND ARTICLES (CLASS 1) IN PACKAGES
Materials to be used in the construction of vehicle bodies
No materials likely to form dangerous compounds with the explosive substances carried shall be used
in the construction of the body.
Combustion heaters
Combustion heaters may only be installed on EX/II and EX/III vehicles for heating of the driver’s cab
or the engine.
Combustion heaters shall meet the requirements of 9.2.4.7.1, 9.2.4.7.2, 9.2.4.7.5 and 9.2.4.7.6.
The switch of the combustion heater may be installed outside the driver's cab.
It is not necessary to prove that the heat exchanger is resistant to the reduced afterrunning cycle.
No combustion heaters or fuel tanks, power sources, combustion air or heating air intakes as well as
exhaust tube outlets required for the operation of the combustion heater shall be installed in the load
compartment.
EX/II vehicles
The vehicles shall be designed, constructed and equipped so that the explosives are protected from
external hazards and the weather. They shall be either closed or sheeted. Sheeting shall be resistant to
tearing and be of impermeable material, not readily flammable1. It shall be tautened so as to cover the
loading area on all sides.
All openings in the load compartment of closed vehicles shall have lockable, closefitting
doors or
rigid covers. The driver’s compartment shall be separated from the load compartment by a continuous
wall.
EX/III vehicles
The vehicles shall be designed, constructed and equipped so that the explosives are protected from
external hazards and the weather. These vehicles shall be closed. The driver’s compartment shall be
separated from the load compartment by a continuous wall. The loading surface shall be continuous.
Load restraint anchorage points may be installed. All joints shall be sealed. All openings shall be
capable of being locked. They shall be so constructed and placed as to overlap at the joints.
The body shall be made from heat and flame resistant materials with a minimum thickness of 10 mm.
Materials classified as Class B-s3-d2 according to standard EN 13501-1:2007 + A1:2009 are deemed
to fulfil this requirement.
If the material used for the body is metal, the complete inside of the body shall be covered with
materials fulfilling the same requirement.
1 In the case of flammability, this requirement will be deemed to be met if, in accordance with the procedure
specified in ISO standard 3795:1989 ‘Road vehicles, and tractors and machinery for agriculture and forestry -
Determination of burning behaviour of interior materials’, samples of the sheeting have a burn rate not exceeding 100
mm/min.
Engine and load compartment
The engine propelling an EX/II or EX/III vehicle shall be placed forward of the front wall of the load
compartment; it may nevertheless be placed under the load compartment, provided this is done in such
a way that any excess heat does not constitute a hazard to the load by raising the temperature on the
inner surface of the load compartment above 80 ºC.
External heat sources and load compartment
The exhaust system of EX/II and EX/III vehicles or others parts of these complete or completed
vehicles shall be so constructed and situated that any excess heat shall not constitute a hazard to the
load by raising the temperature on the inner surface of the load compartment above 80 ºC.
Electrical equipment
The electrical installation shall meet the relevant requirements of 9.2.2.1, 9.2.2.2 9.2.2.3, 9.2.2.4,
9.2.2.5, 9.2.2.6, 9.2.2.7, 9.2.2.8 and 9.2.2.9.2.
