The DSC-measurement in a closed glass crucible showed an endothermic effect (melting) in the temperature range 145 - 170 °C and an exothermic decomposition in the temperature range 325 - 400 °C with an energy of 933 J/g.

Applicant's summary and conclusion

Executive summary:

Thermal stability of diuron was investigated by Differential scanning calorimetry according to OECD Guideline 113.
