This Standard covers requirements for hose and hose assemblies in sizes up to andincluding a nominal diameter of 40 mm and for use at temperatures down to -40 °C or -54 °C and up to +50 °C. Hose for conveying liquid fuel is intended for use at a maximum working pressure of 350 kPa. Hose for recovering vapours of fuel is intended for use at a maximum working pressure of 3.5 kPa, including slight negative pressures from vapour assist systems.
