This European Standard specifies the requirements and test methods for automotive LPG (Liquefied Petroleum Gases), which are marketed and supplied in CEN member countries. This standard applies to automotive LPG that is used in vehicles adapted to run on this type of fuel. DANGER - Warn of the risk of fire and explosion when handling LPG and the danger to health that comes with inhaling excessive quantities of LPG. LPG are highly volatile liquid hydrocarbons that are normally stored under pressure. If the pressure is reduced, large quantities of gas will be produced that can form explosive mixtures with air within the flammability limits of 2% V/Va\ 10% V/V. This European Standard includes sampling, handling and testing of LPG. All operations must be performed away from ignition sources such as open flames, non-explosion-proof electrical equipment, and electrostatic discharge. The tests should be carried out, whenever possible, in a fume hood with explosion-proof installation. LPG in its liquid form can cause cold burns to the skin. Protective clothing, such as gloves and safety glasses, should be worn if there is a possibility of skin contact. Any unnecessary inhalation of LPG vapors should be avoided. The operator must not be exposed to atmospheres containing more than 1 800 mg/m3 during a short reference period of 8 h (TWA), or more than 2 250 mg/m3 during a short reference period of 10 min. One of the tests described in this European Standard involves the operator having to inhale a mixture of air and LPG vapour. Special attention should be paid to the security measures included in section 6.2, where a description of this method is made.
