3Classification
Three types of hose are specified，distinguished by their construction，maximum working pressure andminimum 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 andvacuum resistance test.
4Materials and construction4.1 Hoses
Hoses shall consist of an oil and water resistant synthetic rubber lining, one or more layers of textle yarn andan oil and weather resistant synthetic rubber cover.
4.2Hose assemblies
Hose assemblies shall only be manufactured with those hose fittings whose functionality has been verified inaccordance with subclauses 6.1,6.3,6.4 and 6.5 of this European Standard.
5 Dimensions
5.1 Diameters and concentricity
When measured in accordance with EN ISO 4671, the diameters of the hoses shall conform to the valuesgiven in Table 1.BS EN 854 pdf free download.
