Mixture | Composition (%w/w) of test sample | Composition (%w/w) of cellulose | Burning rate of a distance of 200mm (s) | Burning rate (mm/s) |
1 | 90 | 10 | 114 | 1.75 |
2 | 80 | 20 | 116 | 1.72 |
3 | 70 | 30 | 128 | 1.56 |
4 | 60 | 40 | 141 | 1.42 |
5 | 50 | 50 | 168 | 1.19 |
6 | 40 | 60 | 170 | 1.18 |
7 | 30 | 70 | 171 | 1.17 |
In a series of seven composition rates of sample to powdered cellulose, the composition with the highest burning rate was determined to be 90% test sample :10 % powdered cellulose (w/w) with a burning rate of 1.75 mm/s.
A further five measurements were taken using the composition 90% test sample : 10% powdered cellulose (w/w) and the mean burning rate of all six measurements established to achieve a mean burning rate of 1.82 mm/s
Applicant's summary and conclusion
- Interpretation of results:
- other: oxidising: maximum burning rate equal or higher than reference mixture
- Remarks:
- Migrated information considered to be due to the flammable nature of the test material. Current guidelines indicate that the A17 study is not applicable if a substance is classified as highly flammable.
- Conclusions:
- The maximum burning rate of the substance is higher than the maximum burning rate of the reference substance, so the material is considered oxidising according to the criteria of the test. The decreasing burning rate of the substance is observed to decrease with increasing concentration of powdered cellulose, so this result is considered to be an affect of the flammability of the substance rather than an oxidising potential of the substance.
- Executive summary:
The dried test substance was mixed with varying proportions of dried powdered cellulose and a 200mm long pile ignited. The rate of burning was measured and compared to the burning rate of an equivalent 200mm long pile of a reference substance with powdered cellulose. The burning rate of the test substance is higher than the burning rate of the reference substance which means the substance is considered oxidising by the criteria of the test. However, the decreasing burning rate of the substance is observed to decrease with increasing concentration of powdered cellulose, so this result is considered to be an affect of the flammability of the substance rather than an oxidising potential of the substance.
The substance is not considered to have oxidising potential, by the fact that the results observed were deemed to be due to the flammable nature of the substance, rather than any oxidising potential. This conclusion is further validated by assessment of the chemical structure of the substance, which shows no structural concerns for oxidisation potential.
