Reference
Endpoint:
flash point of flammable liquids
Type of information:
experimental study
Adequacy of study:
key study
Reliability:
1 (reliable without restriction)
Qualifier:
according to guideline
Guideline:
ISO 2719 (Determination of flash point - Pensky-Martens closed cup method)
Version / remarks:
2002
Principles of method if other than guideline:
The flash point of a flammable liquid is the lowest temperature at which there will be enough flammable vapor to ignite when an ignition source is applied. The method used for determination of flash point was Pensky-Marten closed cup method.
GLP compliance:
not specified
Type of method:
closed cup
Flash point:
108.6 °C
Atm. press.:
968.4 hPa
Conclusions:
The mean flash point of 3,7-dimethylocta-2,6-dienenitrile (CAS No. 5146-66-7) was 108.66 degree C at 968.4 hPa.
Executive summary:

The flash point determination of3,7-dimethylocta-2,6-dienenitrile(CAS No. 5146-66-7)was done following closed cup method using Pensky-Martens flash point apparatus. The test was conducted in replicates and mean flash point was determined to be 108.66 °C at 968.4 hPa.

Description of key information

The flash point determination of3,7-dimethylocta-2,6-dienenitrile(CAS No. 5146-66-7)was done following closed cup method using Pensky-Martens flash point apparatus. The test was conducted in replicates and mean flash point was found to be 108.66 °C at 968.4 hPa.

Key value for chemical safety assessment

Flash point at 101 325 Pa:
108.66 °C

Additional information

As per the available data for flash point from lab report, authoritative database (Gestis) and predicted data, the flash point value determined was in range from 83 degree C to 108.66 degree C. As the data from lab has K1 reliability and the test was performed using OECD guidelines which has the value of flash point as 108.66 °C at 968.4 hPa thus considered as key study for the chemical safety assessment. Also based on criteria mentioned in CLP regulation the substance 3, 7-dimethylocta-2, 6-dienenitrile was considered to be non flammable.
