BS 2F 67:1980

This standard BS 2F 67:1980 Specification for hose for aviation fuel and engine lubricating oil for aeronautical purposes is classified in these ICS categories:

• 49.035 Components for aerospace construction

This British Standard specifies the requirements for the construction, dimensions, testing and marking of the following three types of hose used for coupling rigid metal pipes, carrying aviation fuel or engine oil of either mineral or synthetic di-ester type, in aircraft.

• Type 1. Woven fabric reinforced hose.
• Type 2. Woven fabric reinforced hose with embedded wire helix.
• Type 3. Braided textile reinforced hose.

The hose is suitable for use at continuous working temperatures from – 40 °C up to 100 °C and at maximum working pressures of a quarter of the specified minimum bursting pressure. At higher temperatures the service life would be progressively shortened.
