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.The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).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. Details of any
patent rights identified during the development of the document will be in the Introduction and/or on
the ISO list of patent declarations received (see www.iso.org/patents).Any trade name used in this document is information given for the convenience of users and does not

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 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 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.
Exchanging codes in accordance with the ISO 21308 standard series is useful in various situations, e.g.
for design and manufacturing, technical specifications, technical drawings and leaflets.
The codes can be communicated via e.g. spreadsheet or XML, or a data exchange system based on the
STEP protocol.© ISO 2019 – All rights reserved

Road vehicles — Product data exchange between chassis and
bodywork manufacturers (BEP) — Part 3: General, mass and
administrative exchange parameters
1 Scope
This document series describes a generic system for the exchange of 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 3 500 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.This document provides codes for the exchange of general, mass and administrative information.

manufacturers and bodywork manufacturers easier without any confusion with other systems

4 Coding principles
4.1 BEP codes of truck chassis and bodywork
Each characteristic, related to truck chassis and bodywork, is assigned a code composed of the items
given below. A prefix “BEP”, followed by a dash (-), shall be used to avoid confusion with other coding
systems.BEP codes are formatted according to the principles in Table 1.

ISO/DIS 21308-3:2019(E)
Table 1 — BEP coding principles
BEP-ppMccc.n.p.q.s.t
Item Assignment Description
pp Bodywork pp = None or 00 for codes related to vehicle chassis (ISO 21308-2 and
category ISO 21308-3)pp = 01 for codes related to loader cranes (ISO 21308-5)
pp = 02 for codes related to hook loaders (ISO 21308-6)
pp = 03 for codes related to skip loaders (ISO 21308-7)
M Measure type A capital letter, which denotes the type of code:
H = Z direction, coordinate system in accordance with ISO 4130
L = X direction, coordinate system in accordance with ISO 4130
W = Y direction, coordinate system in accordance with ISO 4130
C = Coordinate (x,y) or (x,y,z) in the Cartesian coordinate system
M = Mass (m), or mass point (m,x,y,z)
F = Force (static or dynamic)
T = Moment (static or dynamic)
R = Radius
V = Angle
G = General
A = Administrative
ccc BEP code number Code number given by the standard
.n Index number .n is used to designate object number n
.p Entity number .p is used to designate a certain set of object characteristics or entities (e.g.
dimensions, coordinates, address information)Where both .n and .p are specified, they are given in the .n .p order.
.q Corner number .q is used to designate contour corner index number
.s Side designator L or R
.t Type designator Optional coding to describe the object type (e.g. fuel tank)
4.2 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 2019 – All rights reserved
---------------------- Page: 8 ----------------------
ISO/DIS 21308-3:2019(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.4.3 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.4.4 Priority
The column “Priority” shows the priority of the measurements, as follows:
⎯ A – Essential;
⎯ B – Useful.
4.5 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.
4.6 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.4.7 Related XML coding
Any XML implementation for the communication of BEP codes shall follow the requirements given in ISO
21308-1. The XML coding related to this document shall be written according to the indications in Annex
