Specific details on test material used for the study:
Physical State/Appearance: White waxy solid
Purity: 100%, UVCB substance
Storage Conditions: Room temperature in the dark
Key result
Test procedure:
burning rate test: preliminary screening test
Burning time:
8 s
Remarks on result:
other: The pile ignited and burnt with a yellow flame, which self-extinguished 8 seconds after the Bunsen flame was removed, and no propagation of combustion was observed.
Interpretation of results:
GHS criteria not met
Conclusions:
The flammability of the test material was assessed and was classified to be not highly flammable, as it did not propagate combustion over the 200 mm of the preliminary screening test.
Executive summary:

The test material was assessed for its flammable properties by measuring the burning rate of test material prepared as a pile of set dimensions. Testing was conducted using a procedure designed to be compatible with Test N.1. of the United Nations Recommendations on the Transport of Dangerous Goods Manual of Tests and Criteria, 6th revised edition 2015 and Section 2.7 of Regulation (EC) No 1272/2008 of 16 December 2008 on Classification Labelling and Packaging of Substances and Mixtures.

An aluminum mould (250 mm long x 20 mm wide x 10 mm high) was loosely filled with test material (tested after grinding with a pestle and mortar). A non-combustible, non-porous board was placed onto the mould which was then inverted. The mould was removed and an air-rich Bunsen burner flame applied to one end of the pile for 6 seconds, when the test material ignited. The time for combustion to propagate over a distance of 200 mm was measured.

The pile ignited and burnt with a yellow flame, which self-extinguished 8 seconds after the Bunsen flame was removed, and no propagation of combustion was observed.

The flammability of the test material was assessed and was classified to be not highly flammable, as it did not propagate combustion over the 200 mm of the preliminary screening test.
