14、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 established has the right to be represented on that c
15、ommittee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. Draft International Standards adopted by th
16、e 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. International Standard ISO 4414 was prepared by Technical Committee ISO/TC 131, Fluid power systems, Subcommittee SC
17、 9, Installations and systems. This second edition cancels and replaces the first edition (ISO 4414:1982), which has been technically revised. Annexes A to F of this International Standard are for information only. Copyright International Organization for Standardization Provided by IHS under licens

19、utral gas under pressure within a circuit. The application of pneumatic fluid power systems requires a thorough understanding and precise communication between the supplier and purchaser. This International Standard was prepared to assist that understanding and communication and to document many of
20、the good practices learned from experience with pneumatic systems. Use of this International Standard assists: a)the identification and specification of the requirements for pneumatic systems and components; b)the identification of the respective areas of responsibility; c)the design of systems and
21、their components to comply with specific requirements; d)understanding of the safety requirements of a pneumatic system. General rules given in this International Standard have no legal status except those paragraphs that are included in contractual agreements between purchasers and suppliers. Devia
22、tion from those parts of this International Standard included in contractual agreements shall also be agreed to in writing by the purchaser and supplier. Attention shall be drawn by the purchaser and/or the supplier to applicable national and local codes or laws. General rules which contain the verb
23、 “shall“ are counsels of good engineering practice, universally applicable with rare exceptions. Use of the word “should“ in the document is not an indication of choice but an indication that the desirable engineering practices described may have to be modified due to the peculiarities of certain pr
24、ocesses, environmental conditions, or equipment size. Titles or parts of the text which are marked with an asterisk (*) indicate subclauses that discussion is needed between the supplier and purchaser to define the requirements and/or responsibilities. These are also listed in annex A. Copyright Int
