Oxidising properties

Link to relevant study record(s)

Reference

Endpoint:

oxidising liquids

Type of information:

experimental study

Adequacy of study:

key study

Study period:

22 September 2017 to 27 September 2018

Reliability:

1 (reliable without restriction)

Rationale for reliability incl. deficiencies:

guideline study

Qualifier:

according to guideline

Guideline:

EU Method A.21 (Oxidising Properties (Liquids))

Deviations:

yes

Remarks:

Deviations described in "Principles of method if other than guideline".

Principles of method if other than guideline:

Test method EC A.21 specifies that the test mixture of cellulose and the test item is heated until either the burst disc ruptured or until at least 60 seconds had elapsed, however, operator stopped heating the test mixture once a decrease in pressure was observed as this indicated that the reaction had concluded. This was in some cases done before 60 seconds had elapsed. One test item/ cellulose test run was terminated before 60 seconds of heating.

As the test pressure had surpassed the upper requirement of 2070 kPa, the duration for the ressure to increase from 690 kPa to 2070 kPa was significantly greater than the reference item/cellulose mixture and the pressure had decreased in all tests it is beyond doubt that prolonged heating would have made no impact on the results of the test.

GLP compliance:

yes (incl. QA statement)

Specific details on test material used for the study:

- Purity: >98 % This substance has an Unknown or Variable composition, is a Complex reaction product, or a Biological material (UVCB), therefore purity was taken to be 100 %
- Description: Yellow liquid

Contact with:

powdered cellulose

Duration of test (contact time):

60 s

Key result

Sample tested:

test mixture 1:1

Parameter:

mean pressure rise time

Result:

26.345 s

Remarks on result:

spontaneous ignition does not occur

Interpretation of results:

GHS criteria not met

Conclusions:

The test item has been determined to be a non-oxidising liquid.

Executive summary:

The oxidizing properties of the test item has been determined in a study performed to the standardized guideline EU Test Method A.21, under GLP conditions. The test material was found to have a mean pressure rise time greater than that observed for the nitric acid reference sample. The test item is therefore not considered to be an oxidising liquid.
