As none of the available studies can serve as a key study with a sufficiently detailed reporting justifying a Klimisch score of 1 or 2 for the given endpoint, several independent sources were used in a weight of evidence approach. The combined data from handbooks, experimental studies or collection of data provide experimental values in a similar range, supporting the reliability of the result.

Description of key information
The individual study reports (experimental studies, data from handbooks or collection of data) show some deficiencies with respect to the comprehensiveness of the experimental details. Therefore, a reliability of 1 or 2 and thus adequacy as key study was not assignable for any of the individual studies. Consequently, the studies were assigned a Klimisch score of 4 (according to guidance document R.4, ‘not assignable: studies or data […] which are only listed in short abstracts or secondary literature (books, reviews, etc.)). As the individual studies report values are in a similar range, collectively, these studies can be used to conclude on this endpoint and to satisfy the information requirement.
The flash point of 4-nitrotoluene was determined in a series of experimental studies and found to be in the range of 103-106 °C:
Schoeller (Bayer), 1978: The flash point of 4-nitrotoluene is 103 °C at 1013 hPa (DIN 51758, closed cup).
Ullmann's, 2005: The flash point of 4-nitrotoluene is 106 °C at 1013 hPa (closed cup).
Hommel, 1997: The flash point of 4-nitrotoluene is 103 °C. Atmospheric pressure was not reported.
Merck Index, 2006: The flash point of 4-nitrotoluene is 106 °C. Atmospheric pressure was not reported.
ROEMPP, 2009: The flash point of 4-nitrotoluene is 106 °C. Atmospheric pressure was not reported.
The value reported in Schoeller (Bayer), 1978 (103 °C) was chosen as key value for chemical safety assessment, as the corresponding atmospheric pressure and type of method was reported.
