4 Classification
Three types of hose are specified, distinguished by their construction, maximum working pressure and
minimum bend radius
— Type 1TE: hoses with a single layer of textile reinforcement;
— Type 2TE: hoses with one or more braid(s) of textile reinforcement;
— Type 3TE: hoses with one or more braid(s) of textile reinforcement (higher maximum working
pressure).
NOTE Hose Types 1TE are used or low-pressure applications therefore they are not subjected to impulse test
and vacuum resistance test.
Hoses and hose assemblies are not be operated outside the limits of this document.
5 Materials and construction
5.1 Hoses
Hoses shall consist of an oil and water-resistant synthetic rubber lining, one or more layers of textile yarn
and an oil and weather resistant synthetic rubber cover. Two or three braided hose types shall be
separated by an insulating layer of synthetic rubber.
5.2 Hose assemblies
Hose assemblies shall only be manufactured with those hose fittings whose functionality has been
verified in accordance with subclauses 7.1, 7.3, 7.4 and 7.5 of this document.
6 Dimensions
6.1 Diameters and concentricity
The diameters of the hoses shall be measured in accordance with EN ISO 4671 and as such shall conform
to the values in Table 1.
