20、standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International
21、 organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.The procedures used to develop this document and those intended for
22、 its further maintenance are described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the different types of ISO documents should be noted.

27、 hose assemblies Wire- or textile-reinforced single-pressure types for hydraulic applications Specification1 ScopeThis International Standard specifies requirements for ten classes, four grades and seven types of wire- or textile-reinforced hydraulic hoses and hose assemblies of nominal sizes rangin
28、g 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 C to +120 C for types CS, CC and DC.Thi
29、s 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 It is the responsibility of the user, in
30、 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.
