BS EN ISO 3949:2020 pdf free.Plastics hoses and hose assemblies -Textile-reinforced types for hydraulic applications – Specification.
BS EN ISO 3949 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: 一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; 一water-based fluids HFC, HFAE, HFAS and HFB as defined in ISO 6743-4 at temperatures ranging from0°Cto+60°C一water 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.The following documents are referred to in the text in such a way that some or all of their content constitutes requirements of this document.
