Oxidising properties
Administrative data
Link to relevant study record(s)
- Endpoint:
- oxidising solids
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 2010
- Reliability:
- 1 (reliable without restriction)
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.17 (Oxidising Properties (Solids))
- GLP compliance:
- no
- Specific details on test material used for the study:
- The oxidising temperature was measured using TG/DSC (thermogravimetry/differential scanning calorimetry) method. Thermogravimetry
(TG) measures the weight changes that occur when a sample is heated, cooled or held at constant temperature in a defined gas
atmosphere using a controlled temperature program. Differential scanning calorimetry (DSC) is based on the wellproven
Boersma (heat
flux) principle in which the heat flux of a sample and a reference sample are compared. That enables to see endothermic or exothermic
reaction in the sample, which occur when the sample for example melts, vaporizes or when a chemical reaction occurs in the sample.
TGA and DSC measurements are done simultaneously. The thermogravimetrical measurements are done both in nitrogen (N2) and air
flow into the sample chamber heating the sample up to 1000 deg. C using a heating rate of 5 deg. C/min. In the oxidation test, the studies
sample was heated in a Al2O3crucible using air atmosphere. - Key result
- Sample tested:
- test mixture as specified
- Parameter:
- other: thermogravimetry/differential scanning calorimetry
- Result:
- s
- Remarks on result:
- other: The oxidising temperature was measured using TG/DSC (thermogravimetry/differential scanning calorimetry) method. Thermogravimetry (TG) measures the weight changes that occur when a sample is heated, cooled or held at constant temperature in a defined gas
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- No oxidising properties were detected. The mass of the sample decreases step by step all the time on heating, which indicated decomposition
