Any other information on results incl. tables

The test substance melted when approached by the ignition flame.

The test substance did ignite shortly. The reaction ended within the start segment. The substance didn't burn down.

Applicant's summary and conclusion

Conclusions:
The test substance is not highly flammable, does not liberate gases in hazardous amounts and has no pyrophoric properties in the sense of EC guidelines A.10, A. 12 and A.13 and is not subject to classification.
Executive summary:

CIS is not highly flammable in the sense of EC Guideline A 10.

The test substance melted when approached by the ignition flame.The test substance did ignite shortly. The reaction ended within the start segment. The substance didn't burn down.

CIT does not liberate gases in hazardous amounts as defined in EC Guideline A 12. The substance did not emit ignitable gases in hazardous amounts (> 1 L/kg-h) on contact with water.

CIT has no pyrophoric property in the sense of EC Guideline A 13 when being dropped down from a height of 1 m onto a ceramic plate.
