DIN EN ISO 18752:2016-11

This product standard specifies requirements for ten classes, four grades and seven types of wire or textile-reinforced hydraulic hoses and hose assemblies of nominal sizes ranging from 5 to 102. 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 types AS, AC, BS and BC and -40 °C to +120 °C for types CS, CC and DC. This standard does not include requirements for the connection ends. It is limited to the performance of hoses and hose assemblies. The hose assembly maximum working pressure is governed by the lowest maximum working pressure of the components. International Standard ISO 18752 has been adopted into the European body of standards for the first time and is introduced into the German body of standards with this publication. This document has been prepared by Technical Committee ISO/TC 45 "Rubber and rubber products" in cooperation with Technical Committee CEN/TC 218 "Rubber and plastics hoses and hose assemblies", the secretariat of which is held by BSI (United Kingdom). The responsible national standardization committee is Working Committee NA 045-02-12 AA "Gummi- und Kunststoffschläuche sowie Schlauchleitungen (Spiegelgremium zu CEN/TC 218, ISO/TC 45/SC 1)" ("Rubber and plastics hoses and hose assemblies (national mirror committee for CEN/TC 218, ISO/TC 45/SC 1)") at DIN Standards Committee Elastomer Technology (NET).
