10、3:2002(E) iv ISO 2002 All rights reserved 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
11、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 collaborates closely with the International Electr
12、otechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance 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.
13、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 International Standard may be the subject of patent rights. ISO shall not be held responsible for identifying any o
14、r all such patent rights. International Standard ISO 18413 was prepared by Technical Committee ISO/TC 131, Fluid power systems, Subcommittee SC 6, Contamination control and hydraulic fluids. Annexes A to G of this International Standard are for information only. ISO 18413:2002(E) ISO 2002 All rights
15、 reserved v Introduction In hydraulic fluid power systems, power is transmitted and controlled through a pressurized liquid within an enclosed circuit. Contaminants present in the circulating working liquid may degrade system performance. One method of reducing the amount of these contaminants withi
16、n the system is to clean parts and components prior to final assembly. Accurate assessment of the effectiveness of part and component cleanliness requires documentation of both the cleanliness requirement and the methods used for contaminant collection, analysis, and data reporting. -,-,- INTERNATIO
17、NAL STANDARDISO 18413:2002(E) ISO 2002 All rights reserved 1 Hydraulic fluid power Cleanliness of parts and components Inspection document and principles related to contaminant collection, analysis and data reporting 1Scope This International Standard specifies the content of an inspection document
18、that includes both the cleanliness requirement for the specified part or component and the inspection method to be used for evaluating its cleanliness level. The cleanliness requirement and inspection method shall be established and agreed upon by the parties involved. NOTE 1Determination of what co
19、nstitutes an appropriate cleanliness level requirement for any particular part or component is beyond the scope of this International Standard. NOTE 2For the purposes of this International Standard, approved functional liquids are considered to be components. This International Standard is applicabl
20、e to the wetted surfaces of any fluid power system part or component. Appearance defects and contamination by liquid or gaseous materials are not covered by this International Standard. This International Standard does not address safety problems that may arise from hazardous materials, operations a
21、nd equipment associated with its use. The user of this International Standard is responsible for establishing appropriate safety and health practices and determining the applicability of regulatory limitations prior to use. 2Normative references The following normative documents contain provisions w
22、hich, through reference in this text, constitute provisions of this International Standard. For dated references, subsequent amendments to, or revisions of, any of these publications do not apply. However, parties to agreements based on this International Standard are encouraged to investigate the p
23、ossibility of applying the most recent editions of the normative documents indicated below. For undated references, the latest edition of the normative document referred to applies. Members of ISO and IEC maintain registers of currently valid International Standards. ISO 4405, Hydraulic fluid power
