UN/DOT Hazardous Materials Testing

Accurate Classification of Dangerous Goods for Transport

DOT Hazardous Materials Testing - DEKRA Process Safety

Transportation regulations from the United Nations (UN) and the US Department of Transportation (DOT) require classification and testing. 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 a variety of tests for the transportation classification of dangerous goods prescribed by UN and DOT regulations. Our GLP and ISO 17025 compliant testing laboratories are equipped to handle powders, liquids, gases and vapors, 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.

When you partner with us, you benefit not only from our knowledge, experience and first-rate testing facilities, but also from our commitment to creating a personable, friendly and open working environment.

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, closed drum, 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 (Dangerous when wet):

  • Filter paper and conical tests to determine whether reaction with water produces flammable gases

UN Class 5 (Oxidizing Substances and Organic Peroxides)

  • Oxidizing solids and liquids (Test O.1, Test O.2, and Test O.3) for Class 5.1
  • Organic peroxide testing for Class 5.2

UN Class 8 (Corrosives):

  • Corrositex Skin Testing for Packing Group Assessment to determine dermal corrosion
  • ASTM G31 - Immersion Corrosion for metals to measure metal corrosion

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