10、Principes gnraux DD ISO/PAS 21308-1:2007ii iiiForeword 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 mem
11、ber 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 El
12、ectrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards ado
13、pted 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. In other circumstances, particularly when there is an urgent market requirement for such documents, a tech
14、nical committee may decide to publish other types of normative document: an ISO Publicly Available Specification (ISO/PAS) represents an agreement between technical 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 commit
15、tee casting a vote; an ISO Technical Specification (ISO/TS) represents an agreement between the members of a technical committee and is accepted for publication 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 dec
16、ide whether it will be confirmed for a further three years, revised to become an International Standard, or withdrawn.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, it is reviewed again after a further three years, at which time it must either be transformed into an International Standard or be withdrawn.
17、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 identifying any or all such patent rights. ISO/PAS 21308-1 was prepared by Technical Committee ISO/TC 22, Road vehicles, Subcommittee SC 6, Term
18、s and definitions of dimensions and masses. ISO 21308 consists of the following parts, under the general title Road vehicles Product data exchange between chassis and bodywork manufacturers (BEP): Part 1: General principles Publicly Available Specification Part 2: Dimensional bodywork exchange param
19、eters Part 3: General, mass and administrative exchange parameters Part 4: Mapping to STEP application protocol 239 DD ISO/PAS 21308-1:2007iv Introduction Truck chassis manufacturers deal with configuration of chassis in infinite numbers of possible combinations, and bodywork manufacturers produce h
20、ighly customised superstructures on these chassis. Bodywork manufacturers build their superstructures on chassis of several different truck brands. The production efficiency of a specific truck chassis and its body combinations can be greatly improved by communicating in advance with the bodywork ma
21、nufacturer the correct technical and commercial information about the specific chassis. The information needs to be reliable and to give the bodywork manufacturer sufficient confidence to prefabricate the body or the superstructure before the chassis is delivered. With uniform conditions, unambiguou
22、s dimensions and supplementary information can be established, transferred and correctly interpreted by the receiver. Increased information efficiency will improve the quality and reduce the lead times. ISO 21308 specifies a system of codes to exchange specific data between chassis and bodywork manu
23、facturers, providing a platform for efficient communication between the parties. The process of exchanging data in accordance with this part of ISO 21308 is not dependent on a particular level of IT sophistication. Any medium can be used, from fax or e-mail to STEP protocol. Exchanging codes accordi
24、ng to the ISO 21308 standard is useful in various situations, e.g. for design and manufacturing, technical specifications, technical drawings and leaflets. ISO 21308 uses the applicable definitions from the related International Standards ISO 612 and ISO 7656 and adds a number of dimensional codes,
25、together with general, mass and administrative codes. DD ISO/PAS 21308-1:20071Road vehicles Product data exchange between chassis and bodywork manufacturers (BEP) Part 1: General principles 1 Scope ISO 21308 describes general principles for the exchange of data between truck chassis manufacturers an
26、d bodywork manufacturers. It applies to commercial vehicles as defined in ISO 3833, having a maximum gross vehicle mass greater than 3 500 kg. The process of exchanging product data can involve chassis manufacturer, chassis importer, chassis dealer, one or more bodywork manufacturers, and bodywork c
27、omponent suppliers, e.g. manufacturers of demountable bodies, cranes and loading equipment and tipping equipment. This part of ISO 21308 provides an overview and recommendations to assist the parties implementing BEP codes for their communication process. The recommendations cover different ways of
28、communicating and presenting the BEP codes. This part of ISO 21308 also contains some examples of experience from practical use. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For
29、 undated references, the latest edition of the referenced document (including any amendments) applies. ISO 612, Road vehicles Dimensions of motor vehicles and towed vehicles Terms and definitions ISO 7656, Commercial road vehicles Dimensional codes 3 Terms and definitions For the purposes of this do
30、cument, the terms and definitions given in ISO 612 and ISO 7656 apply. DD ISO/PAS 21308-1:20072 4 Benefits of using BEP codes for the involved parties 4.1 Bodywork manufacturer The bodywork manufacturers use of the BEP system will give the following benefits: clear understanding; prefabrication; int
31、ernal time reduction; reliable documentation and information; fewer conflicts between chassis and body parts; detailed information for re-production (additional copies of the bodywork); feedback process easier; fewer late changes and order modifications; easier to work with several different chassis
32、 manufacturers; possibilities for outsourcing parts of the job. 4.2 Chassis manufacturer The chassis manufacturers use of the BEP system will give the following benefits: clear understanding; cut in lead time, better cash flow; communication of chassis features and interfaces; bi-directional communi
33、cation; fewer late changes and order modifications; internal communication between the departments involved; higher quality of the complete work; cost reductions; documentation of the complete vehicle; data for homologation type approval. 4.3 Chassis dealer For the chassis dealer, use of the BEP sys
34、tem will give the following benefits: clear understanding; cut in lead time; cost savings as a result of cut in turnaround time; DD ISO/PAS 21308-1:20073 clear specifications and information to/from the customer; fewer late changes and order modifications; improved quality of the complete vehicle. 4
35、.4 End customer The end customer will benefit from: improved quality; clear specifications and information; shorter delivery time; cost savings. 4.5 Homologation bodies and inspection For homologation parties, the following benefits can be obtained: BEP data related to the legal requirements could b
36、e extracted; annual inspection would be facilitated. 5 Communication of the BEP codes 5.1 Communication methods The following are examples of communication methods: fax; e-mail; web site (which could include, for example, a STEP browser and drawing information); online databases, IT networks; intern
37、al PDM systems. 5.2 Formats of BEP representation The following are possible formats of BEP representation: plain text; comma-separated text (simplest form of structured information); spread-sheets; XML; STEP file (or information derived from a STEP file). DD ISO/PAS 21308-1:20074 5.3 Communication
38、of BEP codes and values It is recommended to use the following simple rules: BEP code to the left; value to the right (see Table 1); the unit should be specified (see Table 1); in drawings, the BEP code relation to the measurement value should be clearly indicated.
