- no
- Remarks on result:
- other: The substance does not melt in the temperature range 30-640ºC.
- Conclusions:
- No endothermic peak corresponding melting of the test substance was recorded in the tested temperature range from 30 to 640 ºC.
Definite values of melting temperature of the test substance, Humic acids, sodium salts, could not be determined in the tested temperature range 30 to 640ºC. - Executive summary:
The melting temperatures of the test substance was determined. The Differential Scanning Calorimetry method was used. The procedures used in the study were in accordance with:
Method A.1. Melting/freezing Temperature (1.4.4.2 Differential scanning calorimetry), Directive 92/69/EEC. Published in OJ No L 383A, December 1992.
