This European Standard specifies the characteristics and performance requirements for tubing and hoses made of either rubber or plastics for use with commercial propane and butane and mixtures thereof@ in the vapour phase@ for the connection of appliances (i.e. for instance@ from pressurized gas container to a regulator@ or a regulator to an appliance or to a metal tube@ or an appliance to a valve) in environments in a temperature range from ?C30 ??to +70 ?? Working pressures are from 0@2 bar to 30 bar. Three classes are defined in Table 1 according to the maximum working pressures and minimal ambient temperatures. This European Standard does not apply to hoses for : ? Welding purposes (see EN ISO 3821) ? Propulsion purposes ? LPG transfer purposes (see EN 1762)
