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

This second edition cancels and replaces the first edition (ISO 21308-2:2006), which has been
technically revised.
The main changes compared to the previous edition are as follows:
— addition of several new codes based on the experiences from the first edition;
— addition of Annex B showing specific XML coding for this part.

Introduction
Truck chassis manufacturers deal with configurations 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
with the bodywork manufacturer in advance. 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.
