Results

Preliminary Screening Test

The pile failed to ignite during the two minutes that the Bunsen flame was applied. The result of the preliminary screening test obviated the need to perform the main test.

Applicant's summary and conclusion

Interpretation of results:
GHS criteria not met
Conclusions:
The test item has been determined to be not highly flammable as it failed to ignite in the preliminary screening test.
Executive summary:

Introduction
The study was conducted to determine the flammability (solids) of the substance. Testing was conducted using a procedure designed to be compatible with Method A10 Flammability (Solids) of Commission Regulation (EC) No 440/2008 of 30 May 2008.

Method

The flammability (solids) was determined by measuring the burning rate of test item prepared as a pile of set dimensions.

Results

During a preliminary test the pile failed to ignite during the two minutes that the Bunsen flame was applied. The result of the preliminary screening test obviated the need to perform the main test.

conclusion

The test item has been determined to be not highly flammable as it failed to ignite in the preliminary screening test.
