Road vehicles — Product data exchange between chassis and bodywork manufacturers (BEP) — Part 3: General, mass and administrative exchange parameters
ISO 21308-3:2007 provides codes for the exchange of general, mass and administrative information. It applies to commercial vehicles, as defined in ISO 3833, having a maximum gross vehicle mass above 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 equipment, tipping equipment.

Foreword
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 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, 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 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 least 75 % of the 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 21308-3 was prepared by Technical Committee ISO/TC 22, Road vehicles, 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
⎯ Part 3: General, mass and administrative exchange parameters
⎯ Part 4: Mapping to STEP application protocol 239

ISO 21308-3:2007(E)
Introduction
Truck chassis manufacturers deal with configuration of chassis in infinite numbers of possible combinations,
and bodywork manufacturers produce highly customized 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 information about the specific chassis communicated in
advance with the bodywork manufacturer. The information must 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 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 for exchanging specific data between chassis and bodywork
manufacturers, providing a platform for efficient communication between the parties. The process of
exchanging data according to 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 according to ISO 21308 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 ISO 612 and ISO 7656 and adds a number of
dimensional codes, together with general, 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.

INTERNATIONAL STANDARD ISO 21308-3:2007(E)
Road vehicles — Product data exchange between chassis and
bodywork manufacturers (BEP) —
Part 3:

1 Scope
This part of ISO 21308 provides codes for the exchange of general, mass and administrative information. It
applies to commercial vehicles, as defined in ISO 3833, having a maximum gross vehicle mass above
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
equipment, tipping equipment.

3 Terms and definitions
For the purposes of this document, definitions given in ISO 612, ISO 1176, ISO 7656, ISO 21308-2, and the
following 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 abbreviation of Bodywork Exchange Parameter.
3.2
Gross Vehicle Mass
GVM
Gross Vehicle Weight
GVW
technical or legal gross vehicle mass (weight) according to the legislation or regulations for the applicable
region
NOTE See also ISO 1176.
4 Coding system
Each dimension given in this International Standard is assigned a code, composed of the items given below.
4.1 BEP code
A prefix “BEP”, followed by a dash (-), shall be used to avoid confusion with other coding systems.
4.2 Type of code
A capital letter, which denotes the type of code, shall be given as follows:
⎯ G – General data;
⎯ M – Mass data;
⎯ A – Administrative data.
If there is a need to differ between items on the right or left side, the BEP code should be supplemented by .R
or .L.
4.3 Numbering
Each item has a unique BEP code consisting of the type letter (see 4.2) and a three-digit sequential number,
starting from 001.
The codes for repeated vehicle items of the same kind on one vehicle, e.g. axles, cross-members, frame-
mounted objects, etc., are differentiated by an added sequential number beginning with .1 counted rearwards
from the front of the vehicle.
For chassis-frame-mounted objects, the same .n number shall be applied to a specific object, both for the
general information on the object and the dimensional codes.

ISO 21308-3:2007(E)
EXAMPLE Information of a fuel tank should be given the code G060.4 when referred to as a frame-mounted object
number 4 according to ISO 21308-2. This applies even if there is only one fuel tank.
NOTE ISO 21308-2 also provides an option for coding the actual object; for example the letter F is used for fuel tank.
If the above method is not possible, the information on the relation between the general coding and the
dimensional coding for a specific object should be provided.
4.4 Code assignment and description
Subclauses 5.1 to 5.3 show the assignment of each BEP code together with a description of its applicability
and limitations.
4.5 Priority
The column “Priority” shows the priority of the measurements, as follows:
⎯ A – Essential;
⎯ B – Useful.
4.6 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.
4.7 Presented in
The column “Presented in” describes in which type of document the items can be presented, as follows:
⎯ 2D – 2D drawing;
⎯ 3D – 3D model;
⎯ TD – Technical data sheet, web site or bodybuilder’s manual, etc.
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 not applicable.
