Reference
A liquid test substance is considered to be an oxidiser if: a 1:1 w/w mixture of the test substance and cellulose spontaneously ignites; or, a 1:1 w/w mixture of the test substance and cellulose exhibits a mean pressure rise time less than or equal to the mean pressure rise time of a 1:1 mixture of 65% w/w aqueous nitric acid and cellulose.
The mean pressure rise time for the reference mixture (1:1 w/w mixture of 65% w/w aqueous nitric acid and cellulose) was 6.2 seconds, while the mean pressure rise time for the test substance mixtures (1:1 w/w mixture of the test substance and cellulose) was 21.7 seconds.
Since the time for the test substance mixture was greater than that for the reference mixture, the test substance was considered to be a non-oxidiser.
Description of key information
The test substance was considered to be a non-oxidiser.
Key value for chemical safety assessment
- Oxidising properties:
- no
Additional information
Justification for classification or non-classification
Substance not classified as it was considered to be a non-oxidiser.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
