Oxidising properties

Link to relevant study record(s)

Reference

Endpoint:

oxidising liquids

Type of information:

experimental study

Adequacy of study:

key study

Study period:

From 23 June 2017 to 28 September 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:

The mean pressure rise time obtained for the references mixtures are not the same than the ones in the guidelines.As the classification of the test item is based on the experimental results of the references mixture, this deviation don't affect the study

GLP compliance:

yes (incl. QA statement)

Specific details on test material used for the study:

SOURCE OF TEST MATERIAL

Contact with:

powdered cellulose

Sample tested:

reference mixture with 50% perchloric acid + cellulose (1:1 ratio)

Parameter:

mean pressure rise time

Result:

> 63 - < 117 ms

Sample tested:

reference mixture with 40% aqueous sodium chlorate + cellulose (1:1 ratio)

Parameter:

mean pressure rise time

Result:

> 321 - < 595 ms

Sample tested:

reference mixture with 65% nitric acid + cellulose (1:1 ratio)

Parameter:

mean pressure rise time

Result:

> 1 914 - < 3 554 ms

Key result

Sample tested:

test mixture 1:1

Parameter:

mean pressure rise time

Remarks on result:

maximum pressure of 2070 kPa not reached

Interpretation of results:

GHS criteria not met

Conclusions:

The test item /cellulose mixture (1:1) didn't reach 2070 kPa. Based on the GHS and CLP criteria, the test item is not classified as oxidising liquid and thus is not assigned to any packing group.

Executive summary:

The oxidising properties of the test item were determined according to recognised guideline and under GLP. The mean pressure rise times of the references mixtures are not the same than the ones indicated in the UN O.2 guideline. As the classification of the test item is based on the comparison of the test item mixture mean pressure rise time and the measured mean pressure rise time of the reference mixtures, this deviation isn't considered to affect the quality of the study.

The test item was mixed with dried cellulose. The mean pressure time rising from 690 kPa to 2070 kPa of the test item/cellulose mixture was compared with the mean pressure rise time of three reference mixtures.

The test item /cellulose mixture (1:1) didn't reach 2070 kPa. Based on the GHS and CLP criteria, the test item is not classified as oxidising liquid and thus is not assigned to any packing group.

Description of key information

The oxidising properties of the test item was determined in a key study of Klimisch validity one, performed according to recognised guideline and under GLP.
