The work of preparing International Standards is normally carried out through IsO technical committees. Each member body interested in a subject for which a technical committee has been non-governmental, in liaison with isO, also take part in the work. sO collaborates closely with the InternationalElectrotechnicalCommission(lEC)onallmattersofelectrotechnicalstandardization. International Standards are drafted in accordance with the rules given in the ISO/lEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. IsO shall not be held responsible for identifying any or all such patent rights. ISO 17165-1 was prepared by Technical Committee ISO/TC 131, Fluid power systems, Subcommittee SC 4, Connectors and similar products and components. Iso 17165 consists of the following parts, under the general title Hydraulic fluid power - Hose assemblies: Part 1: Dimensions and requirements Part2:Recommendedpracticesforhydraulichoseassemblies IS0 2007 - All rights reserved ISO 17165-1:2007(E) Introduction In hydraulic fluid power systems, power is transmitted and controlled through a liquid under pressure within an enclosedcircuit. assemblies make up the flexible part of piping. @ ISo 2007 - All rights reserved INTERNATIONAL STANDARD ISO 17165-1:2007(E) Hydraulic fluid power Hose assemblies - Part 1: Dimensions and requirements 1 Scope elastomericsealsthatconformtoISO12151-1,ISO12151-2,ISO12151-3andISO12151-6.
