Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- The test substance was not classified as an oxidising liquid.
- Executive summary:
The test is conducted to determine the oxidizing properties of the liquid test substance in accordance with the criteria of EC Method A.21.
The test method is designed to measure the potential for a liquid substance to increase the burning rate of a combustible substance, cellulose, or to form a mixture with the combustible substance when thoroughly mixed. The rate of reaction for the test item is compared to that for a reference substance, 65% w/w aqueous nitric acid.
Mean pressure rise time of test substance and reference sample is 10.455 and 2.724 seconds, respectively.
The test item was found to have a mean pressure rise time is greater than the reference sample. Therefore, the test substance was not classified as an oxidising liquid.
