DEKRA Process Safety

UN transportation testing - DEKRA Process Safety

Accurate classification of dangerous goods for transport

In the interest of public safety, transportation regulations from the UN and the US Department of Transportation (DOT) require the classification of certain types of dangerous goods for transport. They also define appropriate tests and procedures to facilitate this classification. If these chemical substances are not properly identified and packaged for safe transport, they can pose a threat to human lives or the environment. Their accidental release could result in fires and explosions or other catastrophes. Accurate, thorough testing provides protection against the risks to life and property inherent in the transportation of hazardous materials in commerce.

We provide the full suite of tests for the transportation classification of dangerous goods prescribed by UN and DOT regulations. Our GLP and ISO 9001 compliant testing laboratory is equipped to handle powders, liquids, gases and vapours, even those classified or believed to be toxic, highly active or controlled. These facilities, together with our expertise, assist clients in complying with regulatory requirements relating to the transportation of hazardous substances.

Comprehensive testing for transport of dangerous goods

Our testing of dangerous goods for transport is based on the UN classification system and includes the full suite of recommended methods and procedures. These include:

    • UN class 1 (Explosives):
      BAM fall hammer, BAM friction and Koenen tube test to measure ignition sensitivity
      Time pressure, UN gap test and fire analysis to measure explosion severity

      • UN class 2 (Aerosols):
        Tests for chemical heat combustion, ignition distance, enclosed space ignition, mist flammability and more
      • UN class 3 (Flammable Liquids):
        Flash point, fire point and sustained combustion testing
      • UN Class 4:

        Division 4.1. (Self-reactive substances and highly-flammable solids):
        Adiabatic storage test to determine the SADT, self-accelerating decomposition temperature
        Burning rate test to determine the ability of a substance to propagate combustion

        Division 4.2 (Self-heating solids, pyrophoric solids and liquids):
        Pyrophoricity test to determine the pyrophoricity of a substance
        Self-heating test to determine the ability of a substance to undergo oxidative self-heating

        Division 4.3 (Substances evolving flammable gases when in contact with water):
        Filter paper and conical tests to determine whether reaction with water produces dangerous gases which may be flammable

All of these tests are performed in accordance with the methods described in the UN and DOT recommendations on the transport of dangerous goods.
