Rubber tubing and hoses for fuel circuits for internal-combustion engines — Specification — Part 2: Oxygenated fuels

Specifies requirements for rubber tubing and hoses for use in fuel circuits using liquid fuels containing oxygenated compounds such as alcohols. Does not cover equipment used for the distribution of liquid fuels. The hoses and unreinforced tubing are used in conventional carburettor systems where fuel is unlikely to become oxidized.
