United Nations, UN, (international) and US Department of Transportation, DOT, (domestic) have developed a scheme for the classification of certain types of dangerous goods and give descriptions of the tests and procedures to arrive at a classification for transport. Dangerous goods are chemical substances or articles containing chemical substances, which can pose threat to public safety or to the environment during transport through chemical, physical, or nuclear properties if not properly identified or packaged. If they are accidentally released undesirable outcomes such as fires and explosions can occur. The purpose of the various tests is to provide adequate protection against the risks to life and property inherent in the transportation of hazardous materials in commerce.
How We Can Help
Chilworth Technology, Inc has the facilities and expertise to conduct the various UN and DOT tests. In addition, Chilworth Technology, Inc. has the familiarity with the regulations and can advise the clients on the classification.
Capabilities
Screening Procedures (CHETAH, DSC, ARC, Dewar)
Class 1 - Explosives , Test series 1, 2 and 3
- UN Gap test (to measure the ability of a substance under confinement to propagate detonation)
- Koenen test (to determine the sensitiveness of a substance to the effect of intense heat under high confinement)
- Time Pressure test (to determine the effects of igniting a substance under confinement)
- BAM Fallhammer test (to measure the sensitiveness to drop weight impact and to determine if the substance is too dangerous to transport in the form tested)
- BAM Friction test (to measure the sensitiveness to friction stimuli and to determine if the substance is too dangerous to transport in the form tested)
- Thermal Stability test (to measure the stability of substance when subjected to elevated thermal conditions to determine if the substance is too dangerous for transport)
- Small Scale Burning test (to determine the response of a substance to fire)
Class 4 and Class 5 - Self Reactive Substances (Division 4.1) and Organic Peroxides (Division 5.2), Test series H
- Adiabatic Storage test (to determine the SADT, self accelerating decomposition temperature)
Class 4 - Readily Combustible Solids (Division 4.1), Test N.1
- Burning Rate Test (to determine the ability of a substance to propagate combustion)
Class 4 - Substances Liable to Spontaneous Combustion (Division 4.2), Tests N.2, N.3 and N.4
- Pyrophoricity test (to determine the pyrophoricity of a substance)
- Self-Heating test (to determine the ability of a substance to undergo oxidative self-heating)
Class 4 - Substances which in Contact with Water Emit Flammable Gases (Division 4.3), Test N.5
- Filter paper and Conical tests (to determine whether reaction with water produces dangerous gases which may be flammable)
Class 5 - Oxidizing Substances (Division 5.1), Tests O.1 and O.2
- Burning time test (to determine the potential to increase the burning rate or intensity)
Please contact Chilworth Technology, Inc., for any other UN and DOT tests not shown above.
