No. 1228, as amended, in accordance with the dates of application specified therein and the provisions
of 9.2.4.7.2 to 9.2.4.7.6 applicable according to the table in 9.2.1.
The combustion heaters and their exhaust gas routing shall be designed, located, protected or covered
so as to prevent any unacceptable risk of heating or ignition of the load. This requirement shall be
considered as fulfilled if the fuel tank and the exhaust system of the appliance conform to provisions
similar to those prescribed for fuel tanks and exhaust systems of vehicles in 9.2.4.3 and 9.2.4.5
respectively.
The combustion heaters shall be put out of operation by at least the following methods:
(a) Intentional manual switching off from the driver's cab;
(b) Stopping of the vehicle engine; in this case the heating device may be restarted manually by the
driver;
(c) Start up of a feed pump on the motor vehicle for the dangerous goods carried.

I. Specific components of motor vehicles using compressed natural gas (CNG) and/or liquefied natural
gas (LNG) in their propulsion systems;
II. Vehicles with regard to the installation of specific components of an approved type for the use of
compressed natural gas (CNG) and/or liquefied natural gas (LNG) in their propulsion system).
7 ECE Regulation No. 67 (Uniform provisions concerning the approval of:
I. Approval of specific equipment of vehicles of category M and N using liquefied petroleum gases in
their propulsion system
II. Approval of vehicles of category M and N fitted with specific equipment for the use of liquefied
petroleum gases in their propulsion system with regard to the installation of such equipment)
8 ECE Regulation No. 122 (Uniform provisions concerning the approval of vehicles of categories M, N and O
with regard to their heating systems)
Afterrunning is permitted after the combustion heaters have been put out of operation. For the
methods of 9.2.4.7.3 (b) and (c) the supply of combustion air shall be interrupted by suitable measures
after an afterrunning cycle of not more than 40 seconds. Only heaters shall be used for which proof
has been furnished that the heat exchanger is resistant to the reduced afterrunning cycle of 40 seconds
for the time of their normal use.
The combustion heater shall be switched on manually. Programming devices shall be prohibited.
Combustion heaters with gaseous fuels are not permitted.
Speed limitation device
Motor vehicles (rigid vehicles and tractors for semitrailers)
with a maximum mass exceeding 3.5
tonnes, shall be equipped with a speed limitation device according to the technical requirements of
ECE Regulation No. 899, as amended. The device shall be set in such a way that the speed cannot
exceed 90 km/h, bearing in mind the technological tolerance of the device.
Coupling devices of motor vehicles and trailers
Coupling devices of motor vehicles and trailers shall comply with the technical requirements of ECE
Regulation No. 552 as amended, in accordance with the dates of application specified therein.
Prevention of other risks caused by fuels
Fuel systems for engines fuelled by LNG shall be so equipped and situated to avoid any danger to the
load due to the gas being refrigerated.
9 ECE Regulation No.89 (Uniform provisions concerning the approval of:
I. Vehicles with regard to limitation of their maximum speed or their adjustable speed limitation function
II. Vehicles with regard to the installation of a speed limiting device (SLD) or adjustable speed limitation
device (ASLD) of an approved type

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.
