Any other information on results incl. tables
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:
- non flammable
- Remarks:
- Migrated information
- Conclusions:
- The test material has been determined to be not highly flammable as it failed to ignite in the preliminary screening test.
- Executive summary:
Method
The flammability (solids) was determined by measuring the burning rate of test material prepared as a pile of set dimensions. Testing was conducted using Method A10 Flammability (Solids) ofCommissionRegulation (EC) No 440/2008 of 30 May 2008.
Procedures
Preliminary screening test
A mould (250 x 20 x 10 mm) was loosely filled with test material (tested as received). A non-combustible, non-porous board was placed onto the mould which was then inverted. The mould was removed and an air-rich Bunsen burner flame applied to one end of the pile for two minutes.
Moisture content
The moisture content was determined gravimetrically.
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.Conclusion
The test material has been determined to be not highly flammable as it failed to ignite in the preliminary screening test.
