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.<\/p>\n

They are suitable for use with:<\/p>\n

    \n
  1. \n

    oil-based hydraulic fluids HH, HL, HM, HR and HV as defined in ISO 6743-4<\/span><\/span> at temperatures ranging from ?40 \u00b0C to +93 \u00b0C;<\/p>\n<\/li>\n

  2. \n

    water-based fluids HFC, HFAE, HFAS and HFB as defined in ISO 6743-4<\/span><\/span> at temperatures ranging from 0 \u00b0C to +60 \u00b0C<\/p>\n<\/li>\n

  3. \n

    water at temperatures ranging from 0 \u00b0C to +60 \u00b0C.<\/p>\n<\/li>\n<\/ol>\n

    This document does not include any requirements for end fittings. It is limited to the performance of hoses and hose assemblies.<\/p>\n

    \n
    \n NOTE\n <\/div>\n

    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.<\/p>\n<\/div>\n
