How does the Oxidising Solids – UN Test O.1 Test work?
Mixtures of a reference oxidiser (potassium bromate) and fuel (cellulose) and the mixtures of the test substance and cellulose are prepared in specific ratios. Using a conical funnel, the mixtures are formed into a truncated conical pile which is inverted onto a looped ignition wire that rests on a low-heat conducting plate. Power is then applied to the ignition wire and is maintained for the duration of the test.
A recorded burning time is taken from when the power is switched on, to when the main reaction (e.g. flame, incandescence or glowing, spontaneous combustion) ends. This test is performed on each ratio five times.
How can UN Test O.1 data help?
Materials and substances that are classified for transportation alongside oxidizing substances are usually based on either guesswork or comparative studies. These are often incorrect and large costs associated with sustainable transport with classified oxidised substances and materials can be avoided. If a product contains a known oxidising constituent, it doesn’t simply mean the product blend should also be classified. Often the product as a whole, is found, through testing not to be.
