Provides requirements for three types of textile-reinforced thermoplastics hose and hose assembly of nominal size from 3,2 to 25.

This International Standard 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 water-based hydraulic fluids HFC, HFAE, HFAS and HFB as defined in ISO6743‑4 at temperatures ranging from 0°C to +60°C and oil-based hydraulic fluids HH, HL, HM, HR and HV as defined in ISO6743‑4 at temperatures ranging from−40°C to +100°C; This International Standard does not include requirements for end fittings. It is limited to the performance of hoses and hose assemblies. NOTE Operating temperatures in excess of 100°C may materially reduce the life of the hose.
