ISO 18752:2022

This document specifies requirements for ten classes, four grades and seven types of wire- or textile-reinforced hydraulic hoses and hose assemblies of nominal sizes ranging from5 to102. Each class has a single maximum working pressure for all sizes.

They are suitable for use with:

— oil-based hydraulic fluids HH, HL, HM, HR and HV as defined in ISO6743‑4 at temperatures ranging from −40°C to +100°C for types AS, AC, BS andBC hoses and from −40°C to +120°C for types CS, CC andDC hoses.

— water-based fluids HFC, HFAE, HFAS and HFB as defined in ISO6743‑4 at temperatures ranging from −40°C to +70°C.

— water at temperatures ranging from 0°C to +70°C.

This document 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 consultation with the hose manufacturer, to establish the compatibility of the hose with the fluid to be used.
