Thermoplastic hoses and hose assemblies — Wire or synthetic yarn reinforced single-pressure types for hydraulic applications — Specification
Preview
Summary
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.
