Endpoint:

Type of information:
other: BUA-report
Adequacy of study:
weight of evidence
Reliability:
4 (not assignable)
Rationale for reliability incl. deficiencies:
secondary literature
Remarks:
No reliability is given as this is a summary entry for the BUA-report.
Justification for type of information:
Due to insufficient reporting of the experimental details, this study was rated with a Klimisch score of 4 (‘not assignable’). 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 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 (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 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 1,2-dichloro-3-nitrobenzene was determined in a series of experimental studies and found to be in the range of 123-152 °C:


Hommel G, 2001: 123°C, atmospheric pressure was not reported.


Bayer AG, 1989: 152 °C


Hoechst, 1985: 124 °C (DIN 51758)


Thiem K-W et al., 1979: 152 °C


National Institute for Occupational Safety and Health; online, 2009: 123 °C, atmospheric pressure was not reported
