- Remarks on result:
- other:
- Remarks:
- Corresponding pressure is not specified, probably at 1013 hPa

- Endpoint:
- flash point of flammable liquids
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- guideline study without detailed documentation
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.9 (Flash-Point)
- GLP compliance:
- no
- Type of method:
- closed cup
- Remarks on result:
- not determinable, other reason:
- Remarks:
- From up 30 °C the ignition flame became greater when dipping into the gas room of the cup. At 75 °C the ignition flame stripped from the ignition burner. The flashpoint cannot be determined exactly.
- Executive summary:
For hydrazine hydrate, no exact flash point could be determined (Currenta, 2010).

Description of key information
The flash point of hydrazine accounts for 38 °C (NIOSH, 1995).
No exact flash point could be determined for hydrazine hydrate (Currenta, 2010).
Key value for chemical safety assessment
- Flash point at 101 325 Pa:
- 38 °C
Additional information
Based on the available information, hydrazine has to be classified as:
- flammable, R10 (Directive 67/548/EEC)
- flammable liquid and vapour, flam. liquid cat. 3 (Regulation EC 1208/2008)
Testing hydrazine hydrate in a closed cup, from up 30 °C the ignition flame became greater when dipping into the gas room of the cup. At 75 °C the ignition flame stripped from the ignition burner. The flashpoint could not be determinded exactly.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation).
