23、SO 17324:2014ISO 17324:2014(E)4 Classification4.1 Types and classesThe hoses are classified into three types as per the intended operating conditions. Type A: hose for connecting air filter and turbocharger, to transfer filtered atmospheric air. Working temperature from 40C to +100C, and vacuum pres
24、sure low to 0,01MPa(0,1bar). Type B: hose for connecting turbocharger and intercooler, to transfer the pressurized and heated air. Working temperature from 40C to +250C.Type B is subdivided into three subtypes as per working temperature and further classified into classes as per maximum working pres
25、sures. The subtypes and classes are shown in Table 1.Table 1 Subtypes and classes for Type BTypeWorking temperatureCClass1 2 3Maximum working pressure MPa(bar)B1 40 approximately +180 0,16(1,6) 0,22(2,2) 0,28(2,8)B2 40 approximately +220 0,20(2,0) 0,28(2,8) 0,34(3,4)B3 40 approximately +250 0,30(3,0
