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.

a)Mass of loss bottle (g)	20.5801	22.6939
b)Mass of loss bottle and test material (g)	21.5562	23.6840
c)Mass of loss bottle and test material after drying (g)	21.5530	23.6807
Moisture content (% w/w)	0.328	0.333
Mean moisture content (% w/w)	0.331

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.

Test	Method	Result
Flammability (Solids)	A10	Not highly flammable.
