Materials and methods

Test guideline
Qualifier:
according to
Guideline:
other: In compliance with United Nations Recommendations on the Transport of Dangerous Goods - Manual of Tests and Criteria Fifth revised edition (2009) - Method O.2 (Part III, Section 34.4.2) EC No. 1272/2008 (CLP)
Deviations:
yes
Remarks:
The deviation was not considered to have affected the quality or the interpretation of the results obtained.
Principles of method if other than guideline:
The test item is mixed in a 1 to 1 ratio by weight with dried fibrous cellulose and introduced into a pressure vessel. If during mixing or filling spontaneous ignition occurs no further testing is necessary and the test item is considered as an oxidizer.
If spontaneous ignition does not occur, the full test is carried out. The mixture is heated in a pressure vessel and the mean time taken for the pressure to rise from 690 to 2070 kPa above atmospheric pressure is determined. This is compared with the mean pressure rise time of three reference items, each one mixed in 1:1 proportion with the dried fibrous cellulose. According to the pressure rise times obtained, the test item is classified in different packing groups.


The following deviation was recorded:
Deviation No. 1: The mean pressure rise time obtained with the sodium chlorate / cellulose mixture recorded was 853 ms instead of about 2500 ms as expected following the guideline.
The mean pressure rise time obtained with the nitric acid / cellulose mixture recorded was 2584 ms instead of about 4767 ms as expected following the guideline.
The mean pressure rise time obtained with the perchloric acid / cellulose mixture recorded was 72 ms instead of about 121 ms as expected following the guideline.
As the pressure rise time of the test item / cellulose mixture recorded was 27817 ms, this deviation was not considered to have affected the quality or the interpretation of the results obtained.
GLP compliance:
yes (incl. certificate)

Applicant's summary and conclusion

Interpretation of results:
other: no oxidising properties
Remarks:
Migrated information
Conclusions:
The mean pressure rise time obtained with the test item / cellulose mixture was higher than the mean pressure rise time obtained with the three mixtures of reference item / cellulose.
The test item was not classified as an oxidising liquid of Division 5.1 and not classified following EC No. 1272/2008 (CLP) under the experimental conditions used.
Executive summary:

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