3) Type 1SN - hoses with a single braid of wire reinforcement;
4) Type 2SN - hoses with two braids of wire reinforcement.
Types 1SN and 2SN shall be of the same reinforcement construction as types 1ST and 2ST, except that they
shall have thinner covers designed to assemble with fittings that do not require removal of the cover or a
portion of the cover.
4 Materials and construction
4.1 Hoses
Hoses shall consist of an oil and water resistant synthetic rubber lining, one or two layers of high tensile steel
wire and an oil and weather resistant rubber cover.
4.2 Hose assemblies
Hose assemblies shall only be manufactured with those hose fittings whose functionality has been verified in
accordance 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 values
given in Table 1.
