Materials and methods
Test guideline
- Guideline:
- other: 5.2.1. Thermogravimetry / differential scanning calorimetry
- Principles of method if other than guideline:
- The oxidation and melting temperatures are measured using TG/DSC (thermogravimetry/ differential scanning calorimetry) method. This measurement is congruent with 92/69/EEC (A.1, 1.4.4.1 and 1.4.4.2).
The thermogravimetrical (TGA) measurements are determined with the STA 409C, manufactured by Netzsch in 1998 and with the TGA/DSC1, manufactured by Mettler Toledo in 2009. Both analyzers provide also a possibility of differential scanning calorimetry (DSC). Thermogravimetry 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 is based on the well-proven Boersma or 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 sample for example melts, vaporizes or when a chemical reaction occurs in the sample. TGA and DSC measurements are done simultaneously and the temperature range in both equipments is from room temperature to 1600 C. Sample type can be liquid, solid or colloid. The accuracy of temperature is 0.5% within 0.3% reproducibility. The resolution of the balance is 1.0 g /11/. The thermogravimetrical measurements are done both in nitrogen (N2) and air flow into the sample chamber heating the sample up to 1500 °C using heating rate 5 °C/min. - GLP compliance:

Results and discussion
Relative self-ignition temperature (solids)
- Remarks on result:
- no self ignition observed under the test conditions
Any other information on results incl. tables
During the melting test, the copper powder sample was heated in Al2O3crucible using nitrogen atmosphere. The TG/DSC curves of the tests are available. The first endothermic peak appears at 1059oC. Based on TG/DSC, and mineral composition the studied material has no self-ignition properties.
