In all tests with the test item and Cellulose in the ratio 4:1 the mixture decomposed flameless very slowly over the complete pile.
In all tests with the test item and Cellulose in the ratio 1:1 the mixture decomposed with a yellowish flame very slowly over the complete pile.
The mean burning times of the test item-to-Cellulose ratio 4.1 and 1:1 are significantly greater than the mean burning time of a 3:7 mixture of Potassium bromate and Cellulose.
UN-Transport regulations
The product has not to be classified as oxidizing solid in Division 5.1 according to the UN-Transport Regulations.
GHS and EC 1272/2008 (CLP-Regulation)
The product has not to be classified as oxidizing solid according to GHS and EC 1272/2008 (CLP-Regulation) Annex 1: 2.14.
Description of key information
The mean burning times of the test item-to-cellulose ratio 4.1 and 1:1 are significantly greater than the mean burning time of a 3:7 mixture of potassium bromate and cellulose.
Key value for chemical safety assessment
- Oxidising properties:
- non oxidising
