Any other information on results incl. tables

 Preliminary Test

The test item did ignite at room temperature using a flame as ignition source, but the flame extinguished after a few seconds without propagation.

Main Test

In the preliminary test the test item could be ignited by a flame within 2 minutes, but the flame extinguished after a few seconds without propagation. Thus, the performance of the main test was not necessary.

Applicant's summary and conclusion

Interpretation of results:
not classified based on GHS criteria
Conclusions:
UN Transport Regulation: The test item does not have to be classified as readily combustible solid in Class 4, Division 4.1 according to the UN Transport Regulation.
GHS (CLP Regulation (EC) No. 1272/2008: Annex 1: 2.7): The test item does not have to be classified as flammable solid according to GHS / CLP Regulation (EC) No. 1272/2008 Annex I: 2.7.
Executive summary:

According to UN Test N.1 and Regulation (EC) No. 440/2008 Method A.10 the test item p-Chlorobenzoic acid could be ignited by a flame, but the flame extinguished after a few seconds without propagation.

The test item does not have to be classified as flammable solid according to GHS / CLP Regulation (EC) No. 1272/2008 Annex I: 2.7.
