9、es (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. International organizations
10、, 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 rules given in the IS
11、O/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 least 75 % of the
12、member bodies casting a vote. 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 21308-2 was prepared by Technical Committee ISO/TC 22, Road vehicle
13、s, Subcommittee SC 6, Terms 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 Part 2: Dimensional bodywork exchange parameters P
14、art 3: General, mass and administrative exchange parameters Part 4: Mapping to STEP application protocol 239 BS ISO 21308-2:2006vIntroduction Truck chassis manufacturers deal with configurations of chassis in infinite numbers of possible combinations, and bodywork manufacturers produce highly custom
15、ized 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 achieving the correct technical and commercial informatio
16、n about the specific chassis communicated with the bodywork manufacturer in advance. The information has to be reliable and give the bodywork manufacturer confidence to prefabricate the body or the superstructure before the chassis is delivered. With uniform conditions, unambiguous dimensions and su
17、pplementary 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 manufacturers, providin
18、g a platform for efficient communication between the parties. The process of exchanging data in accordance with this part of ISO 21308 is irrelevant of IT sophistication degree. Any medium can be used, from fax or e-mail to a STEP protocol. Exchanging codes in accordance with the ISO 21308 series of
19、 International Standards is useful in various situations, e.g. for design and manufacturing, technical specifications, technical drawings and leaflets. This part of ISO 21308 uses the applicable definitions from the related ISO 612 and ISO 7656 and adds a number of dimensional codes, together with g
20、eneral, mass and administrative codes. The codes provide the basic information level, and are also the basic input parameters for a data exchange system based on the STEP protocol.

21、imensional bodywork exchange parameters 1 Scope This part of ISO 21308 provides a set of codes for the exchange of dimensional data between truck chassis manufacturers and bodywork manufacturers. It applies to commercial vehicles as defined in ISO 3833, having a maximum gross vehicle mass above 3 50
22、0 kg. The process of exchanging the above information can involve: chassis manufacturer; chassis importer; chassis dealer; one or more bodywork manufacturers; bodywork component suppliers, e.g. manufacturers of demountable bodies, cranes and loading equipment, tipping equipment. 2 Normative referenc

26、 ISO 1176, ISO 7656, ISO 21308-3, and the following definitions apply. 3.1 BEP-code code to identify a unique measurement on the truck, to make the information exchange between chassis manufacturers and bodywork manufacturers easier without any confusion with other systems NOTE BEP is an abbreviatio

29、SO 21308-3 and ISO 1176. 4 Coding system 4.1 General Each dimension given in this part of ISO 21308 is assigned a code, composed of the items given below. 4.2 BEP code A prefix “BEP”, followed by a dash (-), shall be used to avoid confusion with other coding systems. 4.3 Type of dimension Dimension
30、codes are used to denote length, width and height measurements along the zero X-, Y- or Z-planes respectively, as defined in ISO 4130. They are also used to denote angle measurements. BS ISO 21308-2:20063A capital letter, which denotes the type of dimension, shall be given as follows: L Length; W Wi
31、dth; H Height. NOTE 1 The centre of the first front axle is chosen as a reference zero point for the length measurements. In some cases where it is convenient to use the rear axle as a reference, the first driven rear axle is used. NOTE 2 The top of the chassis frame is chosen as the reference zero
32、point for height measurements for objects connected to the chassis frame. NOTE 3 The centre-line of the chassis is chosen as the reference zero point for width measurements. NOTE 4 The height information, if dependent on the tyres, refers to the actual tyre equipment as described according to ISO 21
33、308-3, if not otherwise stated. If there is a need to differ between the dimension(s) on the right or left side, the BEP-code should be supplemented by R or L. 4.4 Numbering 4.4.1 General Each item has a unique BEP-code consisting of the dimension type letter (see 4.3) and a three-digit sequential n
34、umber, starting from 001. The dimension codes for repeated vehicle items of the same kind on one vehicle, e.g. axles, cross-members, frame-mounted objects, etc., are differed by an added sequential number beginning with .1 counted from the front of the vehicle and rearwards. For L codes, a positive
35、value indicates that the item is located behind the axle. A negative value indicates that the item is located in front of the axle. For H codes, a positive value indicates that the item is located above the top of the chassis frame. A negative value indicates that the item is located below the top o
36、f the chassis frame. 4.4.2 Numbering and type designation of frame-mounted objects The same .n number shall be applied to a specific frame-mounted object in terms of L, H and W dimensions. EXAMPLE Frame-mounted objects may be a fuel tank, referred to as BEP-L030.4, BEP-H030.4, and BEP-W.030.4, and a
37、 battery box, referred to as BEP-L030.5, BEP-H030.5, and BEP-W030.5. For the frame-mounted objects, an optional coding (.t) may be added to describe the object type. The following abbreviation letters are reserved for the object types below: A Air tank; B Battery box; F Fuel tank; H Hydraulic tank;
38、M Exhaust muffler; BS ISO 21308-2:20064 S Spare wheel; T Tool box; U Urea tank. 4.5 Code assignment and description Clauses 5, 6, and 7 of this part of ISO 21308 show the assignment of each BEP-code together with a description of its applicability and limitations. 4.6 Priority The column “Priority”
39、shows the priority of the measurements, as follows: A Essential; B Useful. 4.7 Loading condition The column “Loading” shows the load situation of the chassis, as follows: 1 Unladen; 2 Laden (design mass). NOTE A dash (-) means that the field is not applicable. 4.8 Presented in The column “Presented
40、in” describes in which type of document the items can be presented, as follows: 2D 2D drawing; 3D 3D model; TD Technical data sheet. NOTE An empty field means that there is no specific recommendation for the presentation. It can be covered by any kind of document. A dash (-) means that the field is
