12、al 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 committee. Internatio
13、nal 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. International Standards are drafted in accordance with the rule
14、s given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. 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 l
15、east 75 % of the member bodies casting a vote. In other circumstances, particularly when there is an urgent market requirement for such documents, a technical committee may decide to publish other types of document: an ISO Publicly Available Specification (ISO/PAS) represents an agreement between te
16、chnical experts in an ISO working group and is accepted for publication if it is approved by more than 50 % of the members of the parent committee casting a vote; an ISO Technical Specification (ISO/TS) represents an agreement between the members of a technical committee and is accepted for publicat
17、ion if it is approved by 2/3 of the members of the committee casting a vote. An ISO/PAS or ISO/TS is reviewed after three years in order to decide whether it will be confirmed for a further three years, revised to become an International Standard, or withdrawn. If the ISO/PAS or ISO/TS is confirmed,
18、 it is reviewed again after a further three years, at which time it must either be transformed into an International Standard or be withdrawn. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for i

21、2007(E) ISO 2007 All rights reserved v Introduction 0.1 General Truck chassis manufacturers deal with the configuration of chassis in infinite numbers of possible combinations, and bodywork manufacturers produce highly customized superstructures on these chassis. Bodywork manufacturers build their s
22、uperstructures on chassis of several different truck brands. The production efficiency of a specific truck chassis and its body combinations can be greatly improved by ensuring that the correct technical and commercial information about the specific chassis is communicated with the bodywork manufact
23、urer in advance. The information needs to be reliable such that the bodywork manufacturer has sufficient confidence to prefabricate the body or the superstructure before the chassis is delivered. With uniform conditions, unambiguous dimensions and supplementary information can be established, transf
24、erred and correctly interpreted by the receiver. Increased information efficiency improves quality and reduces lead times. The ISO 21308 series specifies a system of codes to exchange specific data between chassis and bodywork manufacturers, providing a platform for efficient communication between t
25、he parties. The process of exchanging data according to the ISO 21308 series is not dependent on the degree of IT sophistication. Any medium can be used, from fax or e-mail to a STEP (standard for the exchange of product model data) protocol. Exchanging codes in accordance with the ISO 21308 series
26、is useful in various situations, e.g. for design and manufacturing, technical specifications, technical drawings and leaflets. The codes provide the basic information level, and are also the basic input parameters for a data exchange system based on the STEP protocol. This Technical Specification co
27、vers the mapping of these data to STEP application protocol 239 (STEP AP 239). 0.2 Intentions of this Technical Specification This Technical Specification is aimed at those parties interested in using STEP for their transmission of product data. STEP can be implemented in different ways when used fo
28、r the exchange of BEP (bodywork exchange parameter) data. The intention with this Technical Specification is to create a basis for compatible STEP applications when used for exchanging BEP data. In order to achieve this, it is necessary to map the BEP properties to the STEP application in a uniform
29、way. This Technical Specification specifies the general principles of this mapping and shows examples of mapping of specific properties, as well as a complete STEP file for the transmission of data. This Technical Specification is intended for use by implementation and software design experts with i
30、n-depth knowledge of the ISO 10303 series on STEP product data. Special knowledge of object-oriented syntaxes and the data descriptive language of STEP, EXPRESS and EXPRESS-G (the graphical notation) is necessary for the understanding and assimilation of this Technical Specification. 0.3 Relationshi
31、p with STEP The product data model schema of main interest is the ARM (application reference model) contained in STEP application protocol 239 (ISO 10303-239), published in 2005. In addition, complementary standards and documentation are developed within OASIS (a part of W3C) to further assist in a
32、successful usage and implementation of STEP AP 239 based solutions, referred to as data exchange sets (DEXs).

33、lication protocol 239 1 Scope This Technical Specification describes the mapping to STEP application protocol 239 for the exchange of dimensional data between truck chassis manufacturers and bodywork manufacturers. It applies to commercial vehicles, as defined in ISO 3833, which have a maximum gross
34、 vehicle mass greater than 3 500 kg. The process of exchanging the above information can involve the chassis manufacturer, the chassis importer, the chassis dealer, one or more bodywork manufacturers, and bodywork component suppliers, e.g. manufacturers of demountable bodies, cranes and loading equi
35、pment, tipping equipment. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies.

Figure 1 Information exchange model and scope of this Technical Specification Clauses 6 and 7 specify how exchange parameters defined in ISO 21308-2 and ISO 2130
43、8-3 should be mapped against STEP AP 239. NOTE 1 In this Technical Specification, the term “STEP” refers to the STEP AP 239 model. Table 2 identifies how the information entities defined in the Information Content document are generally mapped against the corresponding STEP AP 239 entity. Subclauses
44、 7.1 to 7.12 include an instantiation example diagram with explanatory text, where applicable. NOTE 2 In case of doubt, it is advisable always to refer to the STEP AP 239 documentation and the corresponding DEX capabilities documentation. The instantiation example diagrams show EXPRESS-G instantiati
45、on charts providing an overview of how a cluster of data should be instantiated and grouped. Compulsory relationships may or may not be shown, if relevant in the context. Optional attribute values are typically omitted, e.g. with description attributes that are usually optional and of a descriptive
46、nature (in comparison with data that has a defined semantic meaning in the STEP standard, e.g. the name of a product class). ISO/TS 21308-4:2007(E) 4 ISO 2007 All rights reservedThe STEP standard has many file representation formats (of the same data), the most common being a binding called “Part 21
47、” (ISO 10303-21), which is a plain text file format. XML (Extensible Markup Language) is also available, referred to as “Part 28“ (ISO 10303-28). NOTE 3 Examples using Part 21 and Part 28 are used in this Technical Specification. Annex B summarizes the examples given in this Technical Specification
48、as a complete Part 21 text file. Annex C summarizes in the same way the examples as a complete Part 28 XML file. For complete scheme definitions and descriptions, the ISO 10303-239 documentation should be consulted. 5.2 Mapping techniques and instantiation diagrams This Technical Specification relie
49、s heavily on instantiation diagrams to portray how the BEP data (and additional truck chassis data) is carried in the STEP file. All examples are DEX compliant as far as possible. The model and instantiation diagrams used are in accordance with ISO 10303-11, STEP EXPRESS-G (see Figure 2).
