12、on of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical com- mittees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committ
13、ee. International organizations, governmental and non-governmental, in liai- son with ISO, 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 accordan
14、ce with the rules given in the ISO/IEC Directives, Part 3. 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 d
15、rawn to the possibility that some of the elements of this part of ISO 15171 may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. International Standard ISO 15171-2 was prepared by Technical Committee ISO/TC 131,Fluid power systems, Sub
16、- committee SC 4,Connectors and similar products and components. ISO 15171 consists of the following parts, under the general titleConnections for fluid power and general use Hy- draulic couplings for diagnostic purposes: Part 1: Coupling not for connection under pressure Part 2: Coupling with M162

Introduction In hydraulic fluid power systems, power is transmitted and controlled through a liquid under pressure within an en- closed
18、 circuit. In general applications, a fluid may be conveyed under pressure. Components are equipped with ports providing diagnostic points in a hydraulic system. Diagnostic couplings may be installed to aid in the diagnosis of hydraulic systems. Licensed Copy: sheffieldun sheffieldun, na, Sun Nov 26

20、performance requirements and test procedures for a diagnostic cou- pling with an?straight stud end to mate with an ISO 6149-1 port and an?connection end that can be connected under pressure without tools to a maximum pressure of? 1). The dimensions of the coupling counterpart are specified. The coup
21、ling is designed for use in hydraulic systems that use mineral oil. NOTEThe use of this coupling with fluids other than mineral oil requires an agreement between the supplier and the purchaser. Couplings in accordance with this part of ISO 15171 may be used at a maximum working pressure of (?). The
22、permissible working pressure depends upon the materials, design, working conditions, application, etc. Conformance to the dimensional information in this part of ISO 15171 does not guarantee rated performance. Each manufacturer should perform testing according to the specification contained in this
23、part of ISO 15171 to assure that components comply with the performance rating. 2Normative references The following normative documents contain provisions which, through reference in this text, constitute provisions of this part of ISO 15171.

NOTEThe temperature range of couplings with elastomeric seals depends on the limits of the temperature range of the seals
31、. 4.2Flow rate and pressure drop 4.2.1At a flow rate of?, the pressure drop of the diagnostic coupling shall not exceed?(?). 4.2.2The value of the pressure drop does not include the pressure drop for the hose pin, which is necessary in or- der to carry out the measurements. The pressure drop test sh
32、all be conducted in accordance with ISO 7241-2 and the special provisions given in 4.2.2.1 to 4.2.2.3. 4.2.2.1Conduct a pressure drop test with the complete coupling. 4.2.2.2Conduct a pressure drop test with the poppet and spring removed from the coupling. 4.2.2.3Subtract the value of the pressure d
33、rop obtained from 4.2.2.2 from the pressure drop obtained from 4.2.2.1. The result is the net pressure drop. NOTEThe rating of the male half of the coupling is to be considered without the pressure drop of the pin. 4.3Connection of the coupling with a coupling counterpart If a coupling counterpart i
