UN-DOT Testing

When goods are to be transported, there are many regulations that need to be followed in order to assess and classify the hazards associated with the specific material. This can be an important factor in the design and commercialization of a specific good. Slight changes in the composition of the material may not change the overall end use of the product but could possibly result in a change in its hazard classification. 

Fauske and Associates (FAI) has extensive experience in characterizing the explosive, flammable, oxidizing nature of solids, liquids, vapors and gases.  With this expertise, we are proud to offer a suite of UN/DOT testing of potentially dangerous goods.  “Dangerous goods” may be pure chemical substances, mixtures, or manufactured articles.

Testing Services

FAI offers the following testing services to help determine the proper shipping classification for the following types of hazards.

Jump to:

Class 2: Aerosols

  • Ignition Distanceused to determine the ignition distance of an aerosol spray to assess the associated flame risk in an open environment.  The aerosol is sprayed in the direction of an ignition source at intervals of 15 cm to observe if an ignition, sustained combustion, or flashback of the spray takes place.
  • Enclosed Space Ignition — used to determine the propensity for an aerosol spray to ignite in an enclosed or confined space. The aerosol is sprayed into an enclosed cylindrical test vessel containing a burning candle to observe whether an ignition occurs.

  • Foam Flammability used to determine the flammability of an aerosol spray emitted in the form of a foam, mousse, gel, or paste. The aerosol is sprayed onto a watch glass and an ignition source is introduced in the vapor space above the aerosol contents. If the aerosol ignites, the height of the flame and the duration of the combustion are recorded.
  • Heat of Combustion — used to determine the heat released, or energy, when the liquid components of an aerosol undergo complete combustion with oxygen at standard conditions.

The results from the Ignition Distance, Enclosed Space Ignition, Foam Flammability, and/or Heat of Combustion tests characterize an aerosol as either being non-flammable, flammable, or extremely flammable. The classification of aerosols is critical in determining proper packaging and shipping groups for transportation purposes.

Class 3: Flammable Liquids

  • Flash Point Test – used to classify liquids as either flammable, combustible, or non-flammable in conjunction with a boiling point test. These tests are also used to assigned Model Regulations Packing groups and GHS category for flammability.

  • Fire Point or Sustained Combustion Tests – used to regard flammable liquids as non-flammable for some regulatory purposes if they do not sustain combustion

Class 4: Flammable Solids

Division 4.1: Flammable Solids, Self-Reactive Substances, and Solid Desensitized Explosives

  • Burning Rate Testused to classify materials as “flammable solids”. The test involves exposing a powder train (250 mm x 20 mm x 10 mm) to a flame or hot wire with a temperature of 1000°C.  Classification is then based on the materials burning rate.

Division 4.2: Substances Liable to Spontaneous Combustion

  • Self-Heating Substancesused to determine if substances are “spontaneously combustible”.  The test involves exposing various quantities of sample to temperatures of 100°C, 120°C and 140°C for a period of 24 hours.  During the exposure time, the temperature of the sample is monitored for exothermic activity.  Classification is then based on the occurrence of exothermic activity and the size and temperature at which it occurred.

Division 4.3: Substances, which in Contact with Water, Emit Flammable Gases

  • Dangerous When Wetused to determine if the material is capable of generating flammable gases when it comes into contact with water.  This is a multistep test that involves exposing the material to small quantities of water and evaluating if flammable gases are generated.  Classification is then based on the evidence of flammable gas evolution and the rate at which these gases evolve.

Class 5: Oxidizing Substances

Division 5.1: Oxidizing Solids

  • Oxidizing Solidsused to identify if a material has hazardous oxidizing properties.  The test involves mixing the sample with various quantities of a known combustible material and comparing the burning characteristics to that of a known oxidizer/fuel mixture.  Classification is then based upon how intensely the sample burns.

Division 5.2: Oxidizing Liquids

  • Oxidizing Liquidsused to identify if a material has hazardous oxidizing properties. Specifically, this test method is designed to measure the potential for a liquid substance to increase the burning rate or burning intensity of a combustible substance. The test involves mixing the sample with a known combustible material and comparing the burning characteristics to that of a known oxidizer/fuel mixture.  Classification is based upon how quickly and intensely the sample burns which then determines the necessary packing group for the sample.
