ISO 21308-3:2020(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.

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
---------------------- Page: 7 ----------------------
ISO 21308-3:2020(E)

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 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 B.

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.

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.

---------------------- Page: 7 ----------------------
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.

---------------------- 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.
