3 Classification and materials
The product shall consist of an extruded thermoplastic material with or without an integral reinforcement. The product may also have an inner veneer to impart improved fluid resistance and/or reduced fuel vapour permeability. It may also have an extruded outer cover to improve environmental resistance and/or flame resistance. The outer cover is not necessarily bonded to the tubing or hose.
Six types of tubing and hose for specific applications are specified as follows:
— Type 1: feed and return lines from the fuel tank to the engine compartment — gasoline engines;
— Type 2: feed and return lines from the fuel tank to the engine compartment — diesel engines;
— Type 3: feed and return lines in the engine compartment — moderate-temperature (100 °C) environment —gasoline engines;
— Type 4: feed and return lines in the engine compartment — high-temperature (125 °C) environment
— gasoline engines;
— Type 5: feed lines in the engine compartment — diesel engines;
— Type 6: multi-layer tubing or hoses for vapour lines.
4 Dimensions
Diameters and wall thicknesses shall be as given in Table 1.
The wall thickness shall be the sum of the individual thicknesses of the various elements in the construction of the tubing or hose. The thickness of each individual element shall be such that it is able to carry out its own function and the total function of the tubing or hose.
