Rubber hoses and hose assemblies - Wire- or textile-reinforced single-pressure types for hydraulic applications - Specification

2Scope / Description

This International Standard specifies ten types, four grades and seven types of wire or textile reinforced hydraulic hose and assembly tubes, with nominal sizes ranging from 5 to 102. Each class has a single maximum working pressure on all sizes. Such hoses are suitable for use with hydraulic fluids HH, HL, HM, HR and HV as defined in ISO 6743-4, in the ambient temperature range of -40°C to +100°C for types AS, AC, BS and BC. For types CS, CC and DC, the applicable temperature range is -40°C to +120°C. This International Standard does not include requirements for connection ends. It is limited to the performance of the hose and assembly. The maximum working pressure of the hose assembly is determined by the lowest maximum working pressure in the assembly. Note: The user should consult with the hose manufacturer to determine the compatibility of the hose with the fluid to be used.
