This document specifies the requirements for three classes of wire- or textile-reinforced hydraulic hoses and hose assemblies of nominal sizes ranging from 5 to 25. The hoses and hose assemblies are used in hydraulic jack applications with manually operated hand pumps. They are suitable for use with hydraulic fluids HH, HL, HM, HR and HV at temperature ranging from −40°C to +55°C. For tools that require heavy duty services such as a rescue tool, ISO19718 [ 3 ] applies.
This document does not include requirements for the connection ends. It is limited to the performance of hoses and hose assemblies. The maximum working pressure of hose assemblies is regulated by the lowest maximum working pressure of the components.
NOTE1 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.
NOTE2 There are two International Standards for hoses for hydraulic jacks and tool applications, i.e. ISO16301 and ISO19718 . The comparison table is given in AnnexA.
NOTE3 The classification of HH, HL, HM, HR and HV is found in ISO6743‑4 [ 2 ].
