Interpretation of results:

other: non-flammable

Conclusions:

The flash point of 1-(1-naphthyl)ethanone is 135.3 °C at 978.8 hPa

Executive summary:

The flash point determination of 1-(1-naphthyl)ethanone (CAS No. 941-98-0)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 135.3°C at 978.8hPa. Based on criteria mentioned in CLP regulation the chemical has flash point >than 60 degree C hence the substance was considered to be non-flammable.

Based on criteria mentioned in CLP regulation the chemical has flash point >than 60 degree C hence the substance was considered to be non-flammable.

Key value for chemical safety assessment

Flash point at 101 325 Pa:

135.3 °C

Additional information

Flash point of 1-(1-naphthyl)ethanone (CAS No. 941-98-0) was determined from experimental report of laboratory ,authoritative database and handbook. As the data from laboratory report has K1 reliability and the test was performed using OECD guidelines which have the value of flash point as 135.3 °C at 978.8 hPa thus considered as key study for the chemical safety assessment. Supported to the above data from Gestis database and handbooks the flash point was determined to be 113 and 110 degree C. Thus,based on criteria mentioned in CLP regulation the chemical has flash point >than 60 degree C hence the 1-(1-naphthyl) ethanone (941-98-0) was considered to be non-flammable.

From the available data of 1-(1-naphthyl)ethanone (941-98-0) from gestis database the flash point was determined to be 113 degree C & 110 degree C..
