European foreword
This document (prEN 17321:2018) has been prepared by Technical Committee CEN/TC 119
“Intermodal Loading Units and Cargo Securing”, the secretariat of which is held by DIN.
This document is currently submitted to the CEN Enquiry.

1 Scope
The transport stability of packages is a vital part of transport safety and the possibility of securing the
cargo on different types of Cargo Transport Units (CTUs). This document specifies the requirements for
marking and different methods for testing the transport stability of packages.
A package means the complete product of the packing operation, consisting of the packaging and its
contents prepared for transport.
The transport stability of the packages is divided to different levels depending on the capability to
withstand the forces during the transport. The transport stability of packages requires different types of
CTUs and/or securing methods to obtain safe cargo securing during the entire transport. Due to the
different transport stability of the packages and different types of CTUs, additional securing of the cargo
has to be determined in each specific case.
Before the package is prepared for the transport it can be defined as a handling unit without any
transport packaging material to obtain transport stability. The minimum requirement for the stability of
the handling unit is set to obtain a safe handling both before and after the transport.
The aim of the different test methods is to define the Transport Stability Level (TSL) of a package or
handling unit.

Transport Stability Level (TSL)

4 Requirements, test methods and evaluation
4.1 General requirements
The deceleration values a (g) for stability tests shall be in agreement with already existing standards
like the CTU Code: 2014 (IMO/ILO/UNECE Code of Practice for Packing of CTUs) or EN 12195-1:2010.
The transport stability of the package or handling unit is divided into different Transport Stability
Levels (TSL) based on the horizontal acceleration it can withstand, according to Table 1.
Table 1 — Transport Stability Level
Transport Stability Level (TSL) Horizontal acceleration
a
TSL 1 a ≥ 1,0 g
TSL 2 0,8 g ≤ a < 1,0 g
TSL 3 0,5 g ≤ a < 0,8 g
TSL 4 0,18 g ≤ a < 0,5 g
NOTE For requirements on cargo securing, see EN 12195-1
oSIST prEN 17321:2019
prEN 17321:2018 (E)
Mandatory minimum level of the stability of the handling unit, without any transport packaging
material during handling shall be:
a ≥ 0,18 g (equal to a tilt angle of 10°)
a = acceleration in horizontal direction
g = acceleration of gravity 9,81 m/s
To obtain the mandatory minimum level the test specimen shall be tested free standing with bottom
blocking in the test direction only, not influencing the stability of the test specimen. The test specimen
shall be tested both in longitudinal and transverse direction. For asymmetric cargo, tests in all four
directions are needed.
4.2 Test methods
Verification of conformity to the requirements of this standard shall be provided either by:
a) dynamic deceleration test according to Annex A;
b) dynamic driving test according to EN 12642:2016;
c) static test according to EN 12195-1:2010.
The principles of the different test methods are described below.
1) The principle of a dynamic deceleration test is to apply a defined horizontal deceleration to a test
specimen placed on a movable carriage where test specimen is subject to a controlled stop with the
defined (programmed) acceleration/deceleration characteristic. Depending on the test device
different methods can be used to achieve the deceleration. For instance the carriage may be
stopped by reaction mass of technical devices (hydraulic, air pressure, layer of foam, etc.). The
carriage may alternatively be driven by an electric motor or induction accelerator by which the
controlled stop is performed.
The dynamic deceleration test is described in Annex A. Informative sketches are shown in Annex B.
2) Another option to examine the transport stability of a package or handing unit is to perform a
dynamic driving test with the packages on basis of the tests described in Annex B of the Standard
EN 12642 according to Table 2.

TSL can be tested with any of the three methods with applicable acceleration and duration. For all
TSL the obtained acceleration might be specified on the label.

3) The third option to examine the transport stability of a package or handling unit is to perform a
static test. The principle of a static test is to tilt up a package or a handling unit on basis of D.2 of
standard EN 12195-1:2010 or Annex 7, appendix 5 of the CTU Code. Horizontal acceleration for
transport stability level is calculated according to D.2.3.3 (Formula D.5) of standard
EN 12195-1:2010.
Informative sketches for static test are described in Annex C.
Described test methods can be used only for packages or handling units which do not completely tilt
during testing. The maximum achieved angle before tilting is considered as value for TSL. The tilting
stability of an unsecured
