OTHER SPECIFICS:

Contact with:

other: potassium bromate and dry fibrous cellulose

Duration of test (contact time):

3 min

Key result

Sample tested:

reference: 3:7 mixture potassium bromate + cellulose

Parameter:

mean burning time

Result:

120 s

Key result

Sample tested:

4:1 sample-to-cellulose ratio

Parameter:

mean burning time

Result:

296 s

Key result

Sample tested:

1:1 sample-to-cellulose ratio

Parameter:

mean burning time

Result:

452 s

Interpretation of results:

GHS criteria not met

Conclusions:

The 4:1 and 1:1 test item:cellulose mixtures exhibited mean burning times greater than that of the 3:7 potassium bromate to cellulose mixture. This indicates that the test item is not an oxidizing solid.

Key value for chemical safety assessment

Oxidising properties:

non oxidising
