Understanding DIN 55415 regulations.

DIN 55415 also known as “Transport stability – Test methods to determine the transport stability of unit loads in intermodal transportation,” focuses on transport stability and test methods to determine the transport stability of unit loads in intermodal transportation.

DIN 55415

How to comply with DIN 55415 – German Standard for Transport Stability Testing?

The stability of load units during transportation is a fundamental aspect of ensuring logistical safety. In this article, we will look at the requirements for three different test methods aimed at assessing transport stability to understand how DIN 55415 regulations work.

Intermodal transportation, encompassing individual modes of transportation and the combination of all, includes modalities such as road, rail, and maritime.

DIN 55415

The stability of load units is classified into various categories based on their ability to withstand loads during transportation. Given the variability in transport stability and the different types of load units, it is crucial to determine the need to additionally secure the load in each case.

In this context, it is important to understand that the transport stability class of an individual load unit alone does not provide sufficient information. Moreover, it is uncertain to determine whether the interaction among multiple charge units in the CTU area will trigger a domino effect. Therefore, it remains uncertain whether these units will meet the traffic safety requirements during transportation. This scenario is considered even in situations where the loads are transported without additional safety measures.

It is considered that a cargo unit constitutes a handling unit if it is transported within the internal flow of materials without the need for auxiliary means to form and secure the cargo units. Minimum stability requirements for a handling unit are established to enable safe handling and transshipment processes, both before and after intermodal transportation.

The primary objective of the three testing procedures is to determine a specific Transport Stability Class (TK) for each cargo or handling unit.

Compliance Analysis of DIN 55414 Standard: Requirements and Testing Procedures.

To assess compliance with the DIN 55414 standard, it is crucial to understand the specific requirements that must be met. The speeds used in stability tests for transportation must align with those established in current regulations. This includes the CTU Code: 2014 and the DIN EN 12195-1:2021-01 standard, both focused on packaging for CTU.

General requirements.

Effective acceleration


CT 1 a ≥ 1,0 g
CT 2 0,8 g ≤ a <1,0 g
CT 3 0,5 g ≤ a <0,8 g
CT 4 0,3 g ≤ a <0,5 g
CT 5 0,18 g ≤ a <0,3 g

Note: In this context, the acceleration in the horizontal direction is based on the gravitational acceleration unit, which is equal to 9.81 m/s². For criteria related to load securing safety, it is recommended to refer to the DIN EN 12195-1 standard.

The transported load or handling unit must meet the minimum requirement of the TK 5 transport stability class, which involves withstanding an effective acceleration of a = 0.18 g.

Testing Procedures in DIN 55415.

Dynamic Laboratory Test.

In this procedure, a test sample is exposed to predetermined accelerations and decelerations. The sample is placed on a movable support, subjecting it to a specific acceleration/deceleration curve. To drive this support, various mechanisms can be employed, such as electric motors or hydraulic systems.

Dynamic Driving Test.

According to the DIN EN 12642:2017-03 standard, this approach involves assessing the load safety of the unit by subjecting it to dynamic driving conditions.

During the dynamic evaluation, the sample placed in the cargo area of the transport vehicle undergoes accelerations and decelerations while in motion. This method aligns with the driving test specifications outlined in the DIN EN 12642:2017-03 standard.

a) If more than one testing method is allowed for a Transport Stability Class (TK), the method representing the most unfavorable case should be selected.
b) The prescribed speed in DIN EN 12642:2017-03 must be adhered to. The deceleration must be adjusted according to the TK.
c) The speeds specified in DIN EN 12642:2017-03 must be reduced in accordance with the TK.

Static Tilt Test.

This method is in accordance with the DIN EN 12195-1:2021-01 and DIN EN 12642:2017-03 standards, focusing on testing the load units considering the tilt angle (α) and a predefined tilt speed (vH). The obtained results are evaluated according to specific criteria.

The basis of a static tilt test involves examining a load or handling unit based on the defined tilt angle and tilt speed, following the DIN EN 12195-1:2021-01 standard.

The tilt speed, measured in degrees per second (°/s), is set to ensure a standardized methodology during the test. This determination is supported by results from comprehensive and statistically validated research.

In general terms, the recommended tilt speed is 0.2°/s.
