34、O 18752:2012), of which it constitutes a minor revision, to include data of “Class 490” in Table 7.EN ISO 18752:2016 (E) DIN EN ISO 18752:2016-11 41 ScopeThis International Standard specifies requirements for ten classes, four grades and seven types of wire- or textile-reinforced hydraulic hoses and

35、 hose assemblies of nominal sizes ranging from 5 to 102. Each class has a single maximum working pressure for all sizes. Such hoses are suitable for use with hydraulic fluids HH, HL, HM, HR and HV as defined in ISO 6743-4 at temperatures ranging from 40 C to +100 C for types AS, AC, BS and BC and 40

36、 C to +120 C for types CS, CC and DC.This International Standard does not include requirements for the connection ends. It is limited to the performance of hoses and hose assemblies. The hose assembly maximum working pressure is governed by the lowest maximum working pressure of the components.NOTE

37、It is the responsibility of the user, in consultation with the hose manufacturer, to establish the compatibility of the hose with the fluid to be used.2 Normative referencesThe following referenced documents are indispensable for the application of this document.
