Key result
Flash point:
> 200 °C
Remarks on result:
other: No flash point was observed up to 200 °C

The flash point of the reference substance Naphthalene was determined to be 80 °C, not deviating from the literature value (80 °C). In case of the test item three parallel tests were carried out. The parameters used for the flash point determinations are presented in Table 1 in detail. The measured flash point of Kronnitex TXP: no flash point was observed up to 200 °C.
