Results

Preliminary screening test

The pile ignited with a small yellow flame which self-extinguished after 6 seconds without propagating combustion.

The result of the preliminary screening test obviated the need to perform the main test.

Applicant's summary and conclusion

Interpretation of results:
other: Not highly flammable
Conclusions:
The result of the preliminary screening test obviated the need to perform the main test. The test material has been determined to be not highly flammable as it failed to support combustion in the preliminary screening test
Executive summary:

Hazardous physico-chemical properties were determined using methods specified in Commission Regulation (EC) No 440/2008 of 30 May 2008.
