Link to relevant study record(s)
- Endpoint:
- oxidising solids
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- february 2012
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- other: according to guideline UN O.1
- Qualifier:
- according to guideline
- Guideline:
- other: UN O.1
- Deviations:
- no
- Principles of method if other than guideline:
- the test method is designed to measure the potential for a solid substance to increase the burning rate or burning intensity of a combustible substance when the two are thoroughly mixed. This method is described in the manual UN of tests and criteria, 5th revised edition, [ST/SG/AC.10/11/Rev.5].
- GLP compliance:
- no
- Contact with:
- powdered cellulose
- Duration of test (contact time):
- <= 3 min
- Sample tested:
- other: not specified (migrated information) mean burning time
- Parameter:
- other: mean burning time
- Result:
- > 82.6 s
- Remarks on result:
- other: mean burning time is superior to the 3:7 potassium bromate/cellulose mixture burning time
- Interpretation of results:
- other: no oxidising properties
- Remarks:
- Migrated information
- Conclusions:
- CuGUN substance wich, in both the 4:1 and 1:1 sample-to-cellulose ratio (by mass tested) exhibits mean burning times greater than taht of 3:7 mixture (by mass) of potassium bromated and cellulose. By test results, we conclude that substance CuGUN is not an oxidizing substance, in the sense of the regulation CLP and of the regulation of the transport of dangerous goods.
- Executive summary:
The test UN O.1 method is designed to measure the potential for a solid substance to increase the burning rate or burning intensity of a combustible substance when the two are thoroughly mixed.This method is described in the Manual UN of tests and criteria, 5threvised edition, [ST/SG/AC.10/11/Rev.5].
method:
30,0 g±0,1 g mixtures of the reference substance and cellulose are prepared in the potassium bromate to cellulose ratios of 3:7, 2:3 and 3:2 by mass. 30,0 g±0,1 g mixtures of the substance to be tested and cellulose are prepared in the oxidizer to cellulose ratios of 4:1 and 1:1 by mass.
Using the conical funnel, the mixture should be formed into a truncated conical pile, with a base diameter of 70mm, covering the looped ignition wire (Figure4). The test performed in a ventilated area, at atmospheric pressure with the ambient temperature at 20°C±5°C. Power is applied to the ignition wire and is maintained for the duration of the test or for three minutes if the mixture does not ignite and burn.
The recorded burning time is taken from when the power is switched on to when the main reaction (e.g. flame, incandescence or glowing combustion) ends. The test should be performed five times on the substance.
The results are assessed on the basis of the comparison of the mean burning time with those of the reference mixture, and,
whether the mixture of substance and cellulose ignites and burns.
results:
The sample CuGUN (ref n° 12AE606) which, in both the 4:1 and 1:1 sample-to-cellulose ration (by mass tested) exhibits mean burning times greater than that of the 3:7 mixture (by mass) of potassium bromated and cellulose.
conclusion:
By test results, we conclude that substance CuGUN is not an oxidizing substance, in the sense of the regulation CLP and of the regulation of the transport of dangerous goods.

Description of key information
The test UN O.1 method is designed to measure the potential for a solid substance to increase the burning rate or burning intensity of a combustible substance when the two are thoroughly mixed.This method is described in the Manual UN of tests and criteria, 5threvised edition, [ST/SG/AC.10/11/Rev.5].
The sample CuGUN, in both the 4:1 and 1:1 sample-to-cellulose ratio (by mass tested) exhibits mean burning times greater than that of the 3:7 mixture (by mass) of potassium bromated and cellulose.
Key value for chemical safety assessment
- Oxidising properties:
- no
Additional information
Justification for classification or non-classification
According to the 1272/2008 (CLP) regulation and the regulation of the transport of dangerous good, as both the 4:1 and 1:1 sample-to-cellulose ratio (by mass tested) exhibits mean burning times greater than that of the 3:7 mixture (by mass) of potassium bromated and cellulose, CuGUN is not an oxidizing substance.
