Description of key information
The UVCB substance ‘Naphtha (petroleum), steam-cracked, C8-10 aromatic hydrocarbon fraction, alkylated and oligomerised’ (NAF-AO) (see Chapter 1) is produced in different specifications. Flashpoints of different products range from 158 to 171 °C at 1013 hPa.
Key value for chemical safety assessment
- Flash point at 101 325 Pa:
- 158 °C
Additional information
Studies following the national test guideline DIN 51758 were conducted to determine the flash point of the substance NAF-AO. Due to the UVCB nature of the substance, there is a range of flash points measured for different products and batches. The range of flashpoints begins at 158 °C and extends to 171 °C at 1013 hPa. The lowest value is taken as key value for the chemical safety assessment.
