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

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.
The ISO 21308 series specifies a generic system of codes for exchanging specific data between truck
chassis manufacturers and bodywork manufacturers, providing a platform for efficient communication
between the parties. It applies to commercial vehicles as defined in ISO 3833, having a maximum gross
vehicle mass above 3 500 kg.
Exchanging codes in accordance with the ISO 21308 series is useful in various situations, for example,
for design and manufacturing, technical specifications, technical drawings and leaflets.
The codes can be communicated via, for example spreadsheet or XML, or a data exchange system based
on the STEP protocol.

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.
Table 1 — BEP coding principles
BEP-ppMccc.n.p.q.s.t
Item Assignment Description
pp Bodywork category pp = None or 00 for codes related to vehicle chassis (ISO 21308-2 and this
document)
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 respective part of the ISO 21308 series
.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)
NOTE Supplementary information and support tools of this document are available on the ISO Standards
Maintenance Portal. This information can be found at the following URL: https:// standards .iso .org/ iso/ 21308.
4.2 Numbering
Each item has a unique BEP code consisting of the type letter (see Table 1) 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.
2 © ISO 2020 – All rights reserved
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.
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 speci
