No exothermic reactions could be observed keepting hydrazine hydrate at a temperature of 75 °C over a duration of 14 d. Thus, the SADT is greater than 75 °C.

Executive summary:

Hydrazine hydrate has a Self Accelerating Decomposition Temperature of greater than 75 °C (Currenta, 2010).

Description of key information

Hydrazine hydrate has a Self Accelerating Decomposition Temperature of greater than 75 °C (Currenta, 2010). 

Additional information

Based on the available data, hydrazine hydrate has no self-reactive properties.

Justification for classification or non-classification

Based on the available information, hydrazine hydrate does not fulfill the criterion for classification according to the EC regulation No 1272/2008, Annex I.
