4 Classification
Hoses are designated as one of the following four types depending on their pressure rating at the
specified temperature:
— Type A: General industrial use — light service — for a maximum working pressure of 0,7 MPa (7 bar)
at 23 °C and 0,45 MPa (4, 5 bar) at 60 °C.
— Type B: General industrial use — medium service — for a maximum working pressure of 1 MPa
(10 bar) at 23 °C and 0,65 MPa (6,5 bar) at 60 °C.
— Type C: Heavy service — for a maximum working pressure of 1,6 MPa (16 bar) at 23 °C and 1,1 MPa
(11 bar) at 60 °C.
— Type D: Heavy service — for use in mining and outdoor work — for a maximum working pressure
of 2,5 MPa (25 bar) bar at 23 °C and 1,3 MPa (13 bar) at 60 °C.
