本标准为ISO 23297-2017，标准的英文名称为Thermoplastic hoses and hose assemblies -- Wire or synthetic yarn reinforced single-pressure types for hydraulic applications -- Specification，本标准在2017-11-01发布，在2017-11-01开始实施。
ISO 23297:2017 specifies requirements for eight classes and two types (construction with adhesive bond between layers and construction without adhesive bond between layers) of wire or synthetic yarn reinforced hydraulic hoses and hose assemblies of nominal size from 3,2 to 31,5. 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 grades A and B and ?40 °C to +120 °C for grades C and D. ISO 23297:2017 does not include requirements for end fittings. 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 consultation with the hose manufacturer, to establish compatibility of the hose with the fluid to be used.
