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

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 Hazardous physico-chemical properties of the test item have been determined. Methods employed were designed to be compatible with those specified in Commission Regulation (EC) No 440/2008 of 30 May 2008, Part A: Methods for the determination of physico-chemical properties. Method The flammability (solids) was determined by measuring the burning rate of test item prepared as a pile of set dimensions. Testing was conducted using a procedure designed to be compatible with Method A10 Flammability (Solids) of CommissionRegulation (EC) No 440/2008 of 30 May 2008. 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.
