This document specifies requirements for three types of textile-reinforced thermoplastics hose and hose assembly of nominal size from 3,2 to 25. Each type is divided into two classes dependent on electrical conductivity requirements.

They are suitable for use with:

— oil-based hydraulic fluids HH, HL, HM, HR and HV as defined in ISO 6743‑4 at temperatures ranging from −40 ¦C to +93 ¦C;

— water-based fluids HFC, HFAE, HFAS and HFB as defined in ISO 6743‑4 at temperatures ranging from 0 ¦C to +60 ¦C

— water at temperatures ranging from 0 ¦C to +60 ¦C.

This document does not include requirements for end fittings. It is limited to the performance of hoses and hose assemblies.
