Testing was stopped as none of the test item/cellulose mixtures propagated combustion over the 200 mm.
Conclusion
The test item has been determined not to have oxidizing properties as the test item/cellulose mixtures failed to propagate combustion over the full 200 mm of the test.
Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- The test item has been determined not to have oxidizing properties as the test item/cellulose mixtures failed to propagate combustion over the full 200 mm of the test.
- Executive summary:
The EU A.17 methid was used to determine the oxidising properties of the test item.
Sample and reference burning rates are determined as detailed below:
Reference mixtures were prepared by mixing barium nitrate and cellulose in various ratios (10 to 90% by weight).
Sample mixtures were also prepared by mixing test item and cellulose in various ratios (10 to 90% by weight).
A mould was loosely filled with a slight excess of each mixture. The mould was dropped from a height onto a solid surface. Any excess mixture was scraped off and the lateral limitations of the mould removed. The remaining mixture was smoothed using a roller. A non-porous, non-combustible board was placed on top of the mould which was then inverted and carefully removed forming a pile. One end of the pile was ignited using an air-rich Bunsen burner flame. The time taken for the reaction zone to travel over a distance of 200 mm after propagating an initial distance of 30 mm and details of the mode of reaction were recorded.
The test item has been determined not to have oxidizing properties as the test item/cellulose mixtures failed to propagate combustion over the full 200 mm of the test.
