ISO 3949:2020 Plastics hoses and hose assemblies – Textile-reinforced types for hydraulic applications – Specification
CDN $186.00
Description
This document 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:
Рoil-based hydraulic fluids HH, HL, HM, HR and HV as defined in ISO 6743‑4 at temperatures ranging from −40 °C to +93 °C;
Рwater-based fluids HFC, HFAE, HFAS and HFB as defined in ISO 6743‑4 at temperatures ranging from 0 °C to +60 °C
Рwater at temperatures ranging from 0 °C to +60 °C.
This document does not include any requirements for end fittings. It is limited to the performance of hoses and hose assemblies.
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.
