Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- The burning time of the mixtures of the test item with cellulose (4:1 and 1:1) was greater than the burning time of the reference mixture of potassium bromate and cellulose (3:7).
Due to the tests the test item does not have to be classified as oxidizing solid.
UN Transport Regulation: the test item does not have to be classified as oxidizing solid in Division 5.1 according to the UN Transport Regulation
GHS and EC 1272/2008 (CLP Regulation): the test item does not have to be classified as oxidizing solid according to GHS and EC 1272/2008 (CLP Regulation) Annex 1: 2.14. - Executive summary:
The burning time of the mixtures of the test item with cellulose (4:1 and 1:1) was greater than the burning time of the reference mixture of potassium bromate and cellulose (3:7). Due to the tests the test item does not have to be classified as oxidizing solid.
UN Transport Regulation: the test item does not have to be classified as oxidizing solid in Division 5.1 according to the UN Transport Regulation
GHS and EC 1272/2008 (CLP Regulation): the test item does not have to be classified as oxidizing solid according to GHS and EC 1272/2008 (CLP Regulation) Annex 1: 2.14.
