Reference
Endpoint:
oxidising liquids
Type of information:
experimental study
Adequacy of study:
key study
Study period:
From 16 October 2015 to 26 June 2017
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
guideline study
Qualifier:
according to guideline
Guideline:
UN Manual of Tests and Criteria: Test O.2 (Test for oxidizing liquids)
Deviations:
yes
Remarks:
Mean pressure rise time for NaClO3 and HNO3 were more rapid than values in the guideline. As the result for the test item was even more rapid, this deviation was not considered to have affected the quality or the interpretation of the results obtained.
GLP compliance:
yes (incl. QA statement)
Remarks:
Certificate No 207/10
Contact with:
powdered cellulose
Duration of test (contact time):
<= 10 min
Key result
Sample tested:
reference mixture with 50% perchloric acid + cellulose (1:1 ratio)
Parameter:
mean pressure rise time
Result:
81 ms
Key result
Sample tested:
reference mixture with 40% aqueous sodium chlorate + cellulose (1:1 ratio)
Parameter:
mean pressure rise time
Result:
636 ms
Key result
Sample tested:
reference mixture with 65% nitric acid + cellulose (1:1 ratio)
Parameter:
mean pressure rise time
Result:
3 608 ms
Key result
Sample tested:
test mixture 1:1
Parameter:
mean pressure rise time
Result:
357 ms
Key result
Sample tested:
test mixture 1:1
Remarks:
with inert material
Parameter:
mean pressure rise time
Remarks on result:
maximum pressure of 2070 kPa not reached
Interpretation of results:
Category 2 (oxidising liquids) based on GHS criteria
Conclusions:
The mean pressure rise time obtained with the test item / cellulose mixture was higher than the mean pressure rise time obtained with the mixture of perchloric acid 50% w/w aqueous solution / cellulose and lower than the mean pressure rise time obtained with the mixture of sodium chlorate 40% w/w solution / cellulose.
A complementary test with an inert substance (Kieselguhr) was performed to show whether or not the result obtained was due to other reactions than oxidising reaction and this test confirmed that the test item has to be classified.
Executive summary:

The oxidising properties of trifluoromethanesulfonic anhydride were determined in a study performed in compliance with the UN Method O.2 (Part III, Section 34.4.2) and under GLP.

The mean pressure rise times obtained with the three reference item / cellulose mixtures and with the test item / cellulose mixture were as follows :

- perchloric acid 50% w/w aqueous solution : 81 ms

- sodium chlorate 40% w/w aqueous solution : 636 ms

- nitric acid 65% w/w aqueous solution : 3608 ms

- test item : 357 ms

The mean pressure rise time obtained with the test item / cellulose mixture was higher than the mean pressure rise time obtained with the mixture of perchloric acid 50% w/w aqueous solution / cellulose and lower than the mean pressure rise time obtained with the mixture of sodium chlorate 40% w/w solution / cellulose.

A complementary test with an inert substance (Kieselguhr) was performed to show whether or not the result obtained was due to other reactions than oxidising reaction. No pressure rise was observed and therefore this test confirmed that the test item has to be classified.

The test item was classified in packing group II of Division 5.1 following O.2 method and in category 2 following EC No. 1272/2008 (CLP), under the experimental conditions used.

Description of key information

One reliable key study scored as reliability 1 is available for this endpoint. The oxidising properties of trifluoromethanesulfonic anhydride were determined in a study performed in compliance with the UN Method O.2 (Part III, Section 34.4.2) and under GLP.

The mean pressure rise times obtained with the three reference item / cellulose mixtures and with the test item / cellulose mixture were as follows :

- perchloric acid 50% w/w aqueous solution : 81 ms

- sodium chlorate 40% w/w aqueous solution : 636 ms

- nitric acid 65% w/w aqueous solution : 3608 ms

- test item : 357 ms

The mean pressure rise time obtained with the test item / cellulose mixture was higher than the mean pressure rise time obtained with the mixture of perchloric acid 50% w/w aqueous solution / cellulose and lower than the mean pressure rise time obtained with the mixture of sodium chlorate 40% w/w solution / cellulose.

Key value for chemical safety assessment

Oxidising properties:
oxidising

Additional information

A complementary test with an inert substance (Kieselguhr) was performed to show whether or not the result obtained was due to other reactions than oxidising reaction. No pressure rise was observed and therefore this test confirmed that the test item has to be classified.

Justification for classification or non-classification

The test performed accodring to the UN O.2 method demonstrated that the substance has to be classified in category 2 following EC No. 1272/2008 (CLP).
