BS ISO 23297:2017 specifies requirements for eight classes and two types (construction with adhesive bond between layers and construction without adhesive bond between layers) of wire or synthetic yarn reinforced hydraulic hoses and hose assemblies of nominal size from 3,2 to 31,5. Each class has a single maximum working pressure for all sizes. Such hoses are suitable for use with hydraulic fluids HH, HL, HM, HR, and HV as defined in ISO 6743?4 at temperatures ranging from -40 °C to +100 °C for grades A and B and -40 °C to +120 °C for grades C and D.Cross References:ISO 4671ISO 6803ISO 10619-1ISO 8033ISO 8331ISO 7233ISO 1402ISO 4892ISO 1817ISO 8330ISO 10619-2:2017ISO 17165-1ISO 4397ISO/TR 17784ISO 6743?4ISO 7326:2016All current amendments available at time of purchase are included with the purchase of this document.
