Any other information on results incl. tables

In the vicinity of the heat source in the high-temperature zone the part of the substance surface was melted by brief spark and flame. The melted surface was burning with a large flame. After removing the heat source the combustion disappeared immediately. Grey smoke formed during melting. The color of the melt was black.

Applicant's summary and conclusion

Interpretation of results:
non flammable
Remarks:
Migrated information The melted surface was burning with a large flame. After removing the heat source the combustion disappeared immediately.
Conclusions:
The substance (4-nitrophenyl-acetic acid) should not be considered as flammable and no further testing is required. According to the GHS criteria the measured substance cannot be classified.
