ISO 23297-2017 熱塑性塑料軟管和軟管組件--液壓用線(xiàn)或人造紗增強的單壓型--規范 Thermoplastics hoses and hose assemblies -- Wire or synthetic yarn reinforced single-pressure types for hydraulic applications -- Specification

This document 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.
This document 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.nd edition 2017-11 Thermoplastic hoses and hose assemblies — Wire or synthetic yarn reinforced single-pressure types for hydraulic applications — Specification Tuyaux et flexibles en matière thermoplastique — Types hydrauliques à pression unique, avec armature de fils métalliques ou synthétiques — Spécifications Reference number ISO 23297:2017(E) ？ ISO 2017 ISO 23297:2017(E) COPYRIGHT
