BS 3F 63:1981


This standard BS 3F 63:1981 Specification for low pressure oxygen hose 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 corrugated rubber hose (generally known as Mark 5A hose), of 16 mm internal diameter, used on aircraft to deliver oxygen and air, at pressures up to 0.35 bar1), from pick-up points on the aircraft oxygen supply system to the aircrew harness. The hose is suitable for use at temperatures between – 40 °C and + 70 °C.

1) 1 bar = 105 N/m2 = 100 kPa.
