19、uct lifecycleIn each step of the product lifecycle (ranging from the first idea through development, manufacture, distribution, use and disposal of the product), information from another step or steps is required; moreover, new additional information is generated. Numerous parties and processes are
20、involved in or form part of the product lifecycle. Hence, information needs to be transferred to or exchanged between those parties and processes, across company internal interfaces and across interfaces to external business partners (such as other manufacturers, suppliers and customers).To ensure s
21、uccessful handling of these business operations, it is essential that the communication between parties and processes involved be independent from individual agreements on data and that the data, once created, be readily usable by other parties and in other processes without a need for conversion me
22、chanisms.b) Availability of new electronic mediaTo take advantage of the economic potential of these new media, product information provided by various suppliers needs to be clear and unambiguous (inter-comparable) for a potential buyer.The requirement arising from both of these aspects is that the
23、description of products and processes are: uniformly consistent and unambiguous; neutral (neither company-specific nor software-specific nor product-specific); available in electronic form for ready use without conversion.This is generally true for any business area.For the business area of fluid po
24、wer systems, the situation that led to the decision to prepare ISO 18582 were:a) available ISO Standards, such as the ISO 5598, provide some verbal definitions of properties, but do not provide sufficient detail of information required for an unambiguous data exchange;b) programs (i.e. software, eit
25、her commercially available or custom-made) used in different areas of a single company or amongst business partners (e.g. CAD-Systems, ERP-Systems, Office Tools) use different interfaces and different internal data representation (e.g. measurement unit, reference value); any attempt to exchange data
26、 between them requires multi-directional conversion mechanisms or is associated with a risk of introducing errors or simply is impossible.On the basis of standardized and electronically available properties, data exchange between, and immediate use of transmitted data in, the software used in variou
27、s departments or branches of one company or at various business partners can be implemented. Use of standardized properties increases process comprehensiveness at companies and permits closer IT-based links between customers and suppliers in the areas of development and supply. This, in turn, leads
28、to cost savings by way of cuts in the number of required parts and shorter product-development time frames.Though limited to the field of fluid power, the reference dictionary needs to include all relevant properties required for the full description of fluid power products and processes. Therefore,
29、 in addition to the properties that are peculiar to the field of fluid power systems, the reference dictionary also includes, be it by specification or be it by reference from other dictionaries, properties being of universal nature rather than specific to “fluid power systems”, e.g. quantities and
30、units or fundamental physical entities, and the required properties from other technical fields, e.g. mechanical components such as mountings for fluid power elements, if they are not defined elsewhere (i.e. in ISO 23584) and so cannot be referenced.

32、016(E)Fluid power Specification of reference dictionary Part 1: General overview on organization and structure1 ScopeThis part of ISO 18582 provides the basis for the preparation of a reference dictionary of standardized product properties for the area of fluid power, and for the provision of this r
33、eference dictionary and its entire contents in electronic form.This part of ISO 18582, based on ISO 13584-42 and ISO/IEC Guide 77-2, specifies a reference dictionary of standardized product properties for the area of fluid power.NOTE The properties are determined on the basis of standardized attribu
34、tes. To ensure optimum unambiguity, the standardized properties are classified into definition classes, forming a so-called standardized “reference hierarchy”.2 Normative referencesThe following documents, in whole or in part, are normatively referenced in this document and are indispensable for its

44、N4.3 Basic structure of reference dictionary4.3.1 GeneralFor an unambiguous specification, each property requires a defined context. In accordance with the data model, this context is provided by allocation of each property to an associated definition class.The definition class is one of the mandato
45、ry attributes of a property.When strictly applying the rules of the data model specified in ISO 13584-42, it is impossible to end up with object classes that describe objects in all detail. Therefore, a clear distinction shall be drawn between definition classes and application classes. The properti
46、es defined within the definition classes of the property dictionary can, i.e. in the sense of their defined context, be used in any application class.Within the hierarchic structure of definition classes and within the hierarchic structure of application classes, the rules of heredity, in accordance
47、 with the data model of ISO 13584-42, apply.4.3.2 Basic structure of the hierarchic order of the definition classesThe basic structure of the hierarchic order of definition classes of this part of ISO 18582 is adapted from the ICS (International Classification of Standards).To achieve compatibility
48、with the data model of ISO 13584-42, ICS classes are given a verbal definition and are related to each other by introduction of appropriate classifying properties. The ICS structure is modified to eliminate classes such as “miscellaneous”.On the top level order of the ICS, besides generalities/termi
49、nology/standardization (ICS 01), we have the sciences and the industry sectors. Properties shall always be allocated to the most general possible class (here, ICS class), that is, if a property cannot be allocated to ICS 01 and its subclasses, consideration shall be given to its allocation to the relevant science class, and only if this is not possible shall it be allocated to the relevant industry sector class.4.3.3 Allocation of properties for basic quantities within the hierarchic order of definition classesIn orde
