The work of preparing International Standards is normally carried out through
14、 ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborate
15、s 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/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards
16、. 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
17、 document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights.

18、002 All rithgs reresvde Introduction In hydraulic fluid power systems, power is transmitted and controlled through a liquid under pressure within an enclosed circuit. Manifold assemblies used in hydraulic fluid power systems consist of components installed on standard mounting surfaces or in standar
19、d cavities machined in a manifold. Fluid connections among components in an assembly are concealed within the manifold. Complete, accurate identification of the components and connection ports is needed to install or service a manifold assembly. In normal practice, the system supplier is responsible
20、 for the marking of manifolds and correlation of that marking with documents. Manifold manufacturers commonly share that responsibility through supplier subcontract provisions.

21、 of manifold assemblies and their components 1S c o p e This International Standard provides identification coding for manifolds used in hydraulic systems and for component installation features (for example, mounting surfaces or cavities) of such manifolds. It specifies identification codes to be m
22、arked on manifold blocks and correlated with product and service documentation such as circuit diagrams, bills of material and assembly drawings, for the purpose of facilitating assembly, installation, use and service of systems in which the manifolds are applied. The codes define a unique identifie
23、r traceable to associated documentation for each mounting surface or cavity. The installed component may be marked or tagged with the same identifier when such marking is necessary for clarity in assembly or service. 2 Normative references The following referenced documents are indispensable for the
24、 application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

26、ion 4.1 General requirements Manifolds shall be marked and the resulting marking correlated with documents in accordance with the requirements given in 4.2 and 4.3. In cases of complex systems that also require marking or tagging of the components, such marking or tagging shall fully identify the ma
27、nifold and the mounting surface or cavity on which each component is installed. Additional markings or document references required as information for use or otherwise, such as required by other applicable standards, purchase agreements or regulations, are not affected by the provisions of this Inte
28、rnational Standard. BSISO16874:2004ISO :47861(4002)E 2 ISO 4002 All rithgs reresvde 4.2 Manifold marking Manifolds shall be marked with the following information in permanent characters at least in height: a) For the complete manifold assembly, a unique numerical or alphanumerical identifier identic
29、al to the one used for the same assembly in the complete system circuit diagram or other controlling document, distinguished from individual mounting surface or cavity identifiers by location or other means. b) For each mounting surface for a valve, accessory or other component, and each cavity for
30、a slip-in or screw- in cartridge valve or other component, a unique numerical identifier located adjacent to the mounting surface or cavity it identifies as necessary for clarity in assembly or service. c) For each port, a letter identifier in accordance with ISO 9461, with a number added as needed
31、to make the identifier unique (see Table 1). 4.3 Correlation with documentation 4.3.1 In circuit diagrams or other controlling documents, each manifold assembly shall be designated with a numerical or alphanumerical identifier unique within the diagram or circuit. It shall be feasible to put the mar
32、king on the manifold in full or in recognizable part. Figure 1 shows an example of the marking of a manifold. Figure 2 shows an example of a related circuit diagram for the manifold shown in Figure 1. 4.3.2 For each manifold assembly, the following shall be shown on or with the circuit diagram or ot
33、her controlling document: a) a table of port sizes similar to the example shown in Table 2, listing and describing all ports in the manifold; b) a bill of materials for the assembly similar to the example shown in Table 3, listing and describing all mounting surfaces and cavities in the manifold, al
34、l components to be installed and their locations in the assembly. The following specific requirements shall apply: 1) for modular stack valves, cartridge valve subassemblies that include auxiliary controls, and other sets of components to be installed on a single mounting surface or in a single cavi
35、ty, the components in each set shall be listed in sequence from bottom to top, that is, from the mounting surface outward for a modular valve stack or from the insert outward for a cartridge valve assembly, 2) on the bill of materials, each component shall be numbered according to its position in th
36、e list. The same number shall be used in assembly and service documents to identify each component and its location in the set.
