6、der the direction of the Aerospace Standards Committee, is a revision of BSC13:1960 which is withdrawn. Except for the orifice sizes relating to aviation gasoline (AVGAS), turbine fuel and synthetic lubricants, and the addition of dimensions for replenishment nozzles, it is technically equivalent to
7、 ISO102:1976, published by the International Organization for Standardization (ISO). The standard has been revised to introduce separate sizes of gravity filling orifices for synthetic and non-synthetic lubricants, and for aviation gasoline (AVGAS) and turbine fuel, the former having a diameter smal
8、ler than that for the latter. It also specifies the outside diameters of the associated fuel replenishment nozzles. The adoption of these requirements for fuel filling orifices will minimize the possibility of the incorrect replenishment of aviation gasoline powered aircraft with turbine fuel and it
9、s attendant disastrous consequences. A British Standard does not purport to include all the necessary provisions of a contract. Users of British Standards are responsible for their correct application. Compliance with a British Standard does not of itself confer immunity from legal obligations. Summ

11、 cover.BS2C13:1988 BSI 01-2000 1 1 Scope This BritishStandard specifies the minimum and/or maximum internal diameters of orifices for the gravity filling of aircraft with fuel, lubricants and other liquids. It also specifies the outside diameters of associated replenishment nozzles, and in particula
12、r of those nozzles used for the gravity replenishment of aircraft with aviation gasoline (AVGAS) and turbine fuel.
