Key value for chemical safety assessment

Flash point at 101 325 Pa:
139.3 °C

Additional information

The flash point determination of test chemical was done by closed cup method using Pensky-Martens Flash Point Apparatus. The mean flash point of the test chemical was determined to be 139.3°C at 975.7 hPa.

Based on the data from reliable handbook and authoritative database, the flash point of test chemical was observed to be 143 °C.

Thus, for the purpose of chemical safety assessment we will consider the key study value which is reported as 139.3°C at 975.7 hPa.
