Eight types of hoses for conveying gasoline fuels and oils, including aviation fuels having an aromatic hydrocarbon content of not more than 50%, at temperatures up to 80°C and a vacuum not exceeding 500 mbar.

This British Standard specifies requirements for rubber and plastics hoses and hose assemblies for carrying gasoline, kerosene, fuel and lubricating oils, including aviation fuels with an aromatic hydrocarbon content of not more than 50 %, at temperatures up to 80 °C. All types are suitable for use with a vacuum not exceeding 0.5 bar.

Hoses of types A, AX, B, BX, C and D are for service as ‘dry’ hoses, i.e. drained after use.

NOTE 1. For continuous service the manufacturer should be consulted.

NOTE 2. The attention of the purchaser is drawn to clauses 1, 3 and 8. From each of these clauses the purchaser should clearly indicate his requirements and intentions to the manufacturer at the time of enquiry or order.

NOTE 3. The titles of the publications referred to in this standard are listed on the inside back cover.
