6.1.3. "Type of combustion heater" means devices which do not differ in essential respects such as:
- fuel type (e.g. liquid or gaseous),
- transfer medium (e.g. air or water),
- vehicle location (e.g. passenger compartment or load area).
6.1.4. "Waste-heat heating system" means any type of device using the waste heat from the engine used for propulsion of the vehicle to increase the temperature of the interior of the vehicle, this may include water, oil or air as the transfer medium.
6.2. Specifications: General
The requirements for heating systems are that:
- the heated air entering the passenger compartment shall be no more polluted than the air at the point of inlet to the vehicle,
- the driver and passengers, during road use, will not be able to come into contact with parts of the vehicle or heated air liable to cause burns,
- the exhaust emissions from combustion heaters are within acceptable limits.
The test procedures for verification of each of these requirements are set out in Annexes 4, 5 and 6.
