Bibliography @ ISO 2007 - All rights reserved ii ISO 12151-4:2007(E) Foreword IsO (the International Organization for Standardization) is a worldwide federation of national standards bodies (isO member bodies). 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 sO, also take part in the work. IsO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. 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 12151-4 was prepared by Technical Committee ISO/TC 131, Fluid power systems, Subcommittee SC 4, Connectors and similar products and components. Iso 12151 consists of the following parts, under the general title Connections for hydraulic fluid power and generaluseHose fittings: Part 1: Hose fittings with /SO 8434-3 O-ring face seal ends Part 2: Hose fitings with /SO 8434-1 and 8434-4 24° cone connector ends with O-rings Part3:Hose fittingswith/SO6162-1or/SO6162-2flange ends Part 4: Hose fittings with /SO 6149 metric stud ends Part5:Hosefittingswith/SO8434-237°flaredends Part 6:Hose fittings with /SO 8434-6 60°cone ends ISO 2007 - All rights reserved ISO 12151-4:2007(E) Introduction an enclosed circuit. In general applications, the fluid can be conveyed under pressure. Components are connected through their ports by stud ends on fluid conductor connectors to tubes and pipes or to hose fittings and hoses. @ISO2007-All rights reserved V INTERNATIONALSTANDARD ISO 12151-4:2007(E) Connections for hydraulic fluid power and general use - Hose fittings Part 4: Hose fittings with isO 6149 metric stud ends 1 Scope This part of IsO 12151 specifies the general and dimensional requirements for the design and performance through 38 mm inclusive, in accordance with IsO 4397. NOTE1 NOTE2 Method of attachment of fitting to hose is optional, for example, permanent, field-attachable, push-on, beaded, etc. Also included is a 9o° elbow hose fitting suitable for hose connections made with or without hose clamps in relatively low-pressure applications. NOTE3 See Is0 4038 and ISO 4039 for hose fittings used in hydraulic and pneumatic braking systems on road vehicles (asdefined in the scope of ISO/TC22). These hose fittings (see Figure 1 for a typical example) are for use in hydraulic fluid power systems with hose Normative references The following referenced documents are indispensable for the application of this document.
