What is ISO 3949 about?
ISO 3949 specifies requirements for three types of textile-reinforced thermoplastics hoses and hose assemblies 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
