Parameter:
mean pressure rise time
Result:
23.16 s
Sample tested:
reference mixture 1: 1
Remarks:
Reference mixture= 65 % w/w aqueous nitric acid/ cellulose
Parameter:
mean pressure rise time
Result:
7.7 s
Interpretation of results:
other: Not classified based on CLP criteria.
Remarks:
No oxidising properties
Conclusions:
OS-1600 was found to be non-oxidising.
Executive summary:

A study was performed to determine the oxidising properties of OS-1600 in accordance with EU Method A.21.The mean pressure rise time for the reference mixture (1:1 w/w mixture of 65% w/w aqueous nitric acid and cellulose) was 7.7 seconds, while that for the test substance mixtures (1:1 w/w mixture of the test substance and cellulose) was 23.2 seconds. Since the time for the test substance mixture was much greater than that for the reference mixture, the test substance was considered to be a non-oxidiser.

Endpoint:
oxidising liquids
Data waiving:
other justification
Justification for data waiving:
the study does not need to be conducted because there are no chemical groups present in the molecule which are associated with oxidising properties and hence, the classification procedure does not need to be applied

Description of key information

OS-1600 was found to be non-oxidising.

Key value for chemical safety assessment

Oxidising properties:
no

Additional information

Data waiving (other justification): Test substance does not contain any chemical groups that will cause or contribute to the combustion of other material. Oxime group is not an oxidizing agent.

Key study: A study was performed to determine the oxidising properties of OS-1600 in accordance with EU Method A.21.The mean pressure rise time for the reference mixture was 7.7 seconds, while that for the test substance mixtures was 23.2 seconds. Since the time for the test substance mixture was much greater than that for the reference mixture, the test substance was considered to be a non-oxidiser.

Justification for classification or non-classification

Based on the available data, the test substance was determined to be non-oxidised and therefore, it is not classified in accordance with CLP Regulation (EC) no. 1272/2008.
