12、yet been published by DIN as a standard on account of certain reservations about the content or due to the fact that its creation process differs from the standard. No draft has been published for this DIN SPEC. Please tell us what you think of this DIN SPEC preferably in a file with a table, e-mail
13、ed to nsm din.de. The template for this table is available for download from http:/www.din.de/stellungnahme; or send a hard copy to the Standards Committee on Product Properties (NSM). In addition to the statutory units, the DIN Properties Dictionary (www.DIN) also lists units which are not approved
14、 in Germany. You are strongly advised that the use of these units in official communications and commercial transactions within Germany in accordance with the German Law on Legal Units for Measurement is prohibited. The units are cited merely as an aid in official communications and commercial trans
15、actions (for example, in imports and exports) with countries which use these units.

20、troduction The properties system and the tables and lists of article characteristics in accordance with the DIN 4000 series of standards are commonly used in companies, mainly for the internal recording of parts, their management and re-use. The DIN 4000-based principle has proven effective in limit
21、ing content to a few characteristic features or properties. Within the scope of DIN 4000 these properties are called article characteristics. It was not the purpose of the DIN 4000 series of standards to provide a complete description of material items, nor generally a description of immaterial item
22、s. However, there are increasingly frequent and more urgent calls for standardized and unambiguous data exchange between the different functional areas within a company as well as between manufacturers, suppliers and customers. Secure exchange of clearly defined product data, from the idea to develo
23、pment, production and market launch, right through to the maintenance and disposal of the products involved is essential for making the most of the economic potential of e-business practices (e-marketplaces, e-product catalogues and lifecycle management, etc.). Tables and lists of article characteri
24、stics in accordance with the DIN 4000 series of standards cannot fulfil these requirements, not least because of their restrictions, due to data technology constraints at the time of their creation, and the resulting lack of flexibility and precision. The solution to creating unambiguous data exchan
25、ge is to develop further the structure of the article properties, by clearly defining the properties on the basis of standardized attributes. Using properties standardized according to DIN 4002, objects can be described clearly and can be classified and hierarchized in any way without adversely affe
26、cting data exchange. Standardi ed properties are provided conveniently in electronic form, kept up-to-date online at all times in the DIN Properties Dictionary (www.DIN) for visualization purposes and prepared in IT terms for processing by computer. zFor reasons of clarity, the properties are alloca
27、ted to a standardized scope. This scope defines the object classes for which the properties are valid within the DIN Properties Dictionary. The main theoretical principles behind this approach originated in the international and European ISO 13584 and EN 61360 series of standards on the basis of the
28、 concept of object orientation. However, there are two impediments to applying these standards more widely: Firstly, while these two standards are based on the same information model (ISO 13584-42 and EN 61360-2), their starting points are completely different (ISO: CAD parts libraries; IEC: descrip
29、tion of electronic components). This results in restrictions and the need for arrangements to be made regarding the transfer to other applications. Furthermore, the implementation of these ISO and EN standards calls for a far-reaching understanding of the underlying methodology. This series of docum
30、ents summarizes the discussions which are currently ongoing between the partners involved in the Product Property Standards Committee in DIN and creates a practicable solution to the structure of the DIN Properties Dictionary. It also serves the purpose of allowing tried-and-tested, further developm
31、ent proposals for ISO, IEC and EN standards to be circulated. The standardized content of the DIN Properties Dictionary is published exclusively in electronic data form on the Internet (www.DIN). 4 DIN SPEC 4002-102:2011-05 1 Scope 1.1 Scope of the DIN 4002 series of documents This series of documen
32、ts specifies a procedure for compiling and standardizing structural elements in accordance with the international series of documents ISO/IEC Guide 77, ISO 13584, IEC 61360 and ISO 29002, whereby these structural elements form the normative content of the DIN Properties Dictionary. The DIN 4002 seri
33、es also specifies: a) details and explanatory information regarding the description of the attributes of structural elements and of logical relationships between structural elements; b) rules governing the provision of content to fill structural elements; c) definition of a processing sequence for c
34、ompiling and standardizing structural elements; d) definition of data for the transfer of structural elements by experts to the DIN Properties Dictionary; e) compatible supplements to ISO 13584-32 or ISO/TS 13584-35, which practical experience has shown to be necessary and which are not contained in
35、 ISO 13584, IEC 61360 and ISO 29002. NOTE 1 These supplements can also include additional definitions for the exchange of structural data between software applications. This series of documents does not apply to the exchange of structural elements and their contents between software applications, ap
36、art from definitions which are exclusively supplementary, i.e. not contained in ISO 13584, IEC 61360 or ISO 29002. NOTE 2 The exchange of data structure and data content between software applications should take place in accordance with the definitions in ISO 13584-32 or ISO/TS 13584-35. 1.2 Scope o
37、f this document This Part 102 of the DIN 4002 series describes units and quantities which are made available in the DIN Properties Dictionary in electronic form, but which are not standardized as structural elements. The aim is to provide an inherently consistent collection of units and quantities f
38、or a wide range of applications. These units and quantities are provided in the DIN Properties Dictionary for information purposes, with each unit referring to the source(s) from which it has been taken. The definition of identifiers in the units ensures unambiguous cross-referencing of the units in
39、 information processing systems and facilitates access via web service interfaces, among others. The identifiers are structured in accordance with ISO/TS 29002-5. In addition, the human-readable representation of identifiers in accordance with the standards in the DIN 4002 series is retained. This d
40、ocument also serves as a link between the machine-readable identification of units according to DIN, IEC, ISO (planned), PROLIST, eClss, as well as UCUM and human-readable representation of units in German and English. NOTE In this document the decimal sign is a “comma“. Due to reasons of data proce
41、ssing the decimal sign in the DIN Properties Dictionary (www.DIN) is a “point“, see Table 9. 5 DIN SPEC 4002-102:2011-05 2 Normative references The following referenced documents are indispensable for the application of this document.

45、N 4002-5 and DIN 4002-16 apply. 4 Relationship between quantities, units and their systems 4.1 The International System of Quantities (ISQ) and the International System of Units (SI) The International System of Quantities (ISQ) contains the set of base quantities and all the derived quantities which
46、 are defined by a given set of equations on the basis of the base quantities. This International System of Quantities (ISQ) is used for the systematic classification of physical quantities. It is determined by the definition of a multitude of base quantities (see Table 1). By definition, a base quan
47、tity cannot be expressed through other base quantities. However, according to agreed calculation rules, any number of quantities from the ISQ can be derived from the base quantities (see DIN 4002-5). Every quantity in the International System of Quantities (ISQ) is assigned precisely one SI base uni
48、t (see Table 1). The International System of Units (SI) is formed by the set of SI base units and their derived units. 1) Translators note: Referred to in the English translation of this standard instead of DIN 1301-1:2010-10, which is the normative reference given in the original German version. 6
