- guideline study
- Qualifier:
- according to guideline
- Guideline:
- UN Manual of Tests and Criteria: Test O.1 (Test for oxidizing solids)
- Version / remarks:
- 2015

- Contact with:
- powdered cellulose
- Key result
- Sample tested:
- reference: 3:7 mixture potassium bromate + cellulose
- Parameter:
- mean burning time
- Result:
- 60 s
- Key result
- Sample tested:
- 4:1 sample-to-cellulose ratio
- Parameter:
- mean burning time
- Result:
- 137 s
- Key result
- Sample tested:
- 1:1 sample-to-cellulose ratio
- Parameter:
- mean burning time
- Result:
- 474 s
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- The mean burning times of the substance/cellulose mixtures were both greater than that of the potassium bromate/cellulose mixture, indicating that the substance is not an oxidising solid.
- Executive summary:
The oxidising properties of the substance were studied under GLP to UN Test O.1. Tests were conducted on the test substance when mixed with dry fibrous cellulose in ratios of 1:1 and 4:1, by mass, of sample to cellulose. The burning characteristics of the mixtures were compared with a standard 3:7 reference mixture, by mass, of potassium bromate to cellulose.
The mixtures were prepared individually for each test to give a total weight of 30.0 ± 0.1 g. Each test mixture was formed into a conical pile of base diameter 70 mm, covering a looped ignition wire resting on a low heat conducting base plate. Electrical power (150 ± 7 W) was applied to the ignition wire for a minimum of three minutes if no reaction took place, or until the end of the test if the mixture showed signs of ignition (e.g. flames, incandescence or glowing combustion). For the 4:1 test substance mixtures, the reaction was characterised by a delayed, short-lived flame and heavy fuming, usually leaving more than half of the conical pile untouched. For the 1:1 test substance mixtures, there was still heavy fuming and the flames lasted slightly longer, but the majority of the conical pile had decomposed by the end of the reaction. The burning time was recorded from the initial application of power to the wire until the end of the main reaction. The mean burning time from five evaluations was used for comparisons between mixtures. The reference mixture had a mean burning time of 60 seconds (48 to 67 s), the 1:1 mixture of test substance to cellulose had a mean burning time of 137 seconds (60 to 189 s) and the 4:1 mixture of test substance to cellulose had a mean burning time of 474 seconds (360 to 540 s).
Reference
Applied power to the ignition coil: 150 ± 7 W
For the 4:1 test substance mixtures, the reaction was characterised by a delayed, short-lived flame and heavy fuming, usually leaving more than half of the conical pile untouched. For the 1:1 test substance mixtures, there was still heavy fuming and the flames lasted slightly longer, but the majority of the conical pile had decomposed by the end of the reaction.
Description of key information
Not oxidising as the mean burning times of 1:1 and 4:1 mixtures of test substance to fibrous cellulose were greater than the mean burning time of the 3:7 reference mixture of potassium bromate to cellulose (GLP, UN Test O.1)
Key value for chemical safety assessment
- Oxidising properties:
- non oxidising
