- Executive summary:
The determination of oxidising properties was carried out acconding to Recommendations on the Transport of dangerous goods: Manual of Tests and Criteria, 6th edition, New York and Geneva, 2015: Part III, Division 5.1, Section 34, Test O.1.
Mixture of the reference item and Cellulose were prepared in the potassium bromate to Cellulose ratio of 3:7 and mixture of the test item and Cellulose were prepared in the test item to Cellulose ratio of 4:1 and 1:1. Using the conical funnel, the mixture was formed into a truncated conical pile, with a base diameter of 70 mm, covering the looped ignition wire resting on the low heat conducting plate. The plate was placed in a ventilated area and the test performed at atmospheric pressure with the ambient temperature 20 ± 5 °C.
Power was applied to the ignition wire and was maintained for the duration of test or for 3 min if the mixture did not ignite and burn. The recorded burning time was taken from when the power was switched on to when the main reaction ended. The test was performed five times on test item.
The burning time of mixtures of test item with cellulose (4:1 and 1:1) was higher than the burning time of reference mixture of potassium bromate and cellulose (3:7). Due to tests results, test item does not have to be classified as oxidizing solid.
Conclusion
Non-oxidising agent.
Referenceopen allclose all
Test item mixture burns only in the area of the ignition wire. The flame expires after about 1 min. even if the ignition wire is kept in operation.
Since the mixture burned much slower than the reference substance cellulose mixture, it can be concluded that the test substance is not an oxidizer.
REFERENCE SUBSTANCE
The burning time in seconds of the cone shaped file was as follows: 1st test 135 sec; 2nd test 108 sec; 3rd test 124 sec.
The mixture burned down crackling with a yellow-green flame of about 5 cm of height.
RESIDUAL MOISTURE
The test item contained a residual moisture of <0.1 wt. %, which was determined by drying the test item at 50 °C under vacuum.
The reference item Potassium Bromate contained a residual moisture of <0.1 wt. %, which was determined by drying the reference item at 65 °C.
The reagent Cellulose contained a residual moisture of 6.3 wt.-%, which was determined by drying the reagent at 105 °C.
Burning times of the mixtures of the test item and cellulose
Test item – Cellulose | Test 1 / s | Test 2 / s | Test 3 / s | Test 4 / s | Test 5 / s | Average / s |
4:1 | >180 | >180 | >180 | >180 | >180 | >180 |
1:1 | >180 | >180 | >180 | >180 | >180 | >180 |
REFERENCE MIXTURE
Burning times of the reference mixtures of potassium bromate and cellulose
Potassium bromate – Cellulose | Test 1 / s | Test 2 / s | Test 3 / s | Test 4 / s | Test 5 /s | Average / s |
3:7 | 113 | 112 | 121 | 123 | 108 | 115.4 |
The tests with the mixture potassium bromate:cellulose 2:3 and 3:2 were not performed, because the burning time of the mixtures of test item with cellulose was higher than the burning time of the reference mixtures 3:7.

Justification for classification or non-classification
According to the CLP Regulation (EC) No 1272/2008, oxidizing solid means a solid substance or mixture which, while in itself is not necessarily combustible, may, generally by yielding oxygen, cause, or contribute to, the combustion of other material.
Since the burning time of the mixtures of the test item with cellulose (4:1 and 1:1) was higher than the burning time of the reference mixture of potassium bromate and cellulose (3:7), it was concluded that the test substance does not meet the criteria to be classified as oxidising solid, according to the CLP Regulation (EC) No 1272/2008.
