3.3.. "Evaporative means the hydrocarbon vapours lost from the fuel emissions" system of a motor vehicle 3.3.. "Mono-fuel means a mono-fuel vehicle that primarily runs on gas vehicle" /biomethane, or hydrogen but may also have a petrol system for emergency purposes or starting only, where the petrol tank does not contain more than 15 litres of petrol. 4. Abbreviations General abbreviations BWC Butane PF Permeability APF Assigned OVC-HEV Off- WLTC Worldwide 5. General requirements 5.1. The vehicle and its components liable to affect the evaporative emissions shall be designed, constructed and assembled as to enable the vehicle in normal use and under normal conditions of use such as humidity, rain, snow, heat, cold, sand, dirt, vibrations, wear, etc. to comply with the provisions of this during its useful life determined by Contracting Parties. 5.1.1. This shall include the security of all hoses, joints and connections used within the evaporative emission control systems. 5.1.2. For vehicles with a sealed fuel tank system, this also include having a system which, just before refuelling, releases the tank pressure a vapour storage unit which has the sole function of storing fuel vapour. This ventilation route shall also be the only one used the tank pressure exceeds its safe working pressure. 5.2. 5.3. Vehicle testing condition 5.3.1. The types and amounts of lubricants and coolant for emissions testing shall be as specified for normal vehicle operation by the manufacturer. 5.3.2. The type of fuel for testing be as specified in Annex 2 to this.
