10、he 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 commit
11、tee 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 collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotech
12、nical standardization. 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. International Standard ISO 4413 was prepared by Te
13、chnical Committee lSO/TC 131, Fluid power systems, Subcommittee SC 9, Installations and systems. This second edition cancels and replaces the first edition (ISO 4413:1979), which has been technically revised. Annexes A to D of this International Standard are for information only. ISO 4413:1998(E) IS
14、O vi Introduction In hydraulic fluid power systems, power is transmitted and controlled through a liquid under pressure within an enclosed circuit. The application of hydraulic fluid power systems requires a thorough understanding and precise communication between supplier and purchaser. This Intern
15、ational Standard was prepared to assist that understanding and communication and to document many of the good practices learned from experience with hydraulic systems. Use of this International Standard assists: a)the identification and specification of the requirements for hydraulic systems and com
16、ponents; b)the identification of respective areas of responsibility; c)the design of systems and their components to comply with specific requirements; d)understanding of the safety requirements of a hydraulic system. General rules given in this International Standard have no legal status except tho
17、se paragraphs that are included in contractual agreements between purchasers and suppliers. Deviation 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
18、supplier to applicable national or local codes or laws. General rules that contain the verb “shall” are counsels of good engineering practice, universally applicable with rare exception. Use of the word “should” in the document is not an indication of choice but an indication that the desirable engi
19、neering practices described may have to be modified due to the peculiarities of certain processes, environmental conditions or equipment size. Titles or parts of the text which are marked with an asterisk (*) indicate subclauses for which discussion is needed between the supplier and purchaser to de
20、fine the requirements and/or responsibilities. These are also listed in annex A. INTERNATIONAL STANDARD ISOISO 4413:1998(E) 1 Hydraulic fluid power General rules relating to systems 1 Scope This International Standard provides general rules relating to hydraulic systems on machinery used in industri
21、al manufacturing processes. It is intended as a guide for both suppliers and purchasers, with a view to ensuring: a)safety; b)uninterrupted system operation; c)ease and economy of maintenance; d)long life of the system. 2 Normative references The following standards contain provisions which, through
22、 reference in this text, constitute provisions of this International Standard. At the time of publication, the editions indicated were valid.

39、dition. 3.6 function plate: Surface that contains information describing either the performance of a manually operated device (e.g. on/off, forward/reverse, left/right, up/down) or the status of a function performed by the system (e.g. clamp, lift, advance). 3.7 operating device: Device that provide
40、s an input signal to a control mechanism (e.g. cam, electrical switch). 3.8 piping: Any combination of fittings, couplings or connectors with pipes, hoses or tubes which allows fluid flow between components. 3.9 purchaser: Party that stipulates the requirements of a machine, equipment, system or com
41、ponent and judges whether the product satisfies those requirements. 3.10 supplier: Party that contracts to provide the product(s) to satisfy the purchasers requirements. 3.11 system: Arrangement of interconnected components which transmits and controls fluid power energy. 4 Requirements 4.1 General
42、The requirements given in 4.1.1 to 4.5 apply to all systems within the scope of this International Standard. 4.1.1 Instructions Hydraulic systems shall be installed and used in accordance with the instructions and recommendations of the system supplier. 4.1.2 Language* The purchaser and supplier sha
43、ll agree on the language to be used for machine marking and applicable documentation. The supplier shall be responsible for ensuring that the translation has the same meaning as the original text. 4.2 Hazards* When agreed between the purchaser and supplier, an assessment of the hazards listed in ann
44、ex B shall be performed. This assessment may include the influence of the fluid power -,-,- ISO ISO 4413:1998(E) 5 system on the other parts of the machine, system or environment. Standards listed in annex B may be used in this assessment. So far as is practicable, the hazards identified shall be el
45、iminated by design and, where this is not practicable, the design shall incorporate safeguards against such hazards. 4.3 Safety requirements 4.3.1 Design considerations When designing hydraulic systems, all aspects of possible methods of failure (including control supply failure) shall be considered
46、. In each case, components shall be selected, applied, fitted and adjusted so that in the event of a failure, safety of personnel shall be the prime consideration. The prevention of damage to the system and the environment shall be considered. 4.3.2 Component selection All components in the system s
47、hall be selected or specified to provide for safety in use, and they shall operate within their rated limits when the system is put to its intended use. Components shall be selected or specified to operate reliably under all intended uses of the system. Particular attention shall be paid to the reli
48、ability of components that could cause a hazard in the event of their failure or malfunction. 4.3.3 Unintended pressures All parts of the system shall be designed or otherwise protected against pressures exceeding the maximum working pressure of a system or any part of the system or the rated pressure of any specific component. The preferred means of protection against excessive pressure are one or more pressure relief valves located to limit the pressure in all parts of the system. Alternative means, such a
