Endpoint:
flammable solids
Type of information:
experimental study
Adequacy of study:
key study
Study period:
Between 20 February and 21 February 2012.
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
guideline study
Qualifier:
equivalent or similar to
Guideline:
EU Method A.10 (Flammability (Solids))
Version / remarks:
using a procedure designed to be compatible with Method A10 Flammability (Solids) of Commission Regulation (EC) No 440/2008 of 30 May 2008.
Deviations:
no
GLP compliance:
yes
Test procedure:
burning rate test: preliminary screening test
Remarks on result:
substance does not ignite and propagate combustion either by burning with flame or smouldering along 200 mm of the powder train within the 2 minutes test period

Results

Preliminary Screening Test

The pile failed to ignite during the 2 minutes that the Bunsen flame was applied.

 

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

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

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 Commission Regulation (EC) No 440/2008 of 30 May 2008. The flammability (solids) were determined by measuring the burning rate of the test item. A mould (250 mm long x 20 mm wide x 10 mm high) was loosely filled with test item (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.

       

Conclusion

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

Description of key information

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

Key value for chemical safety assessment

Flammability:
not classified

Additional information

Justification for classification or non-classification

The test item has been determined to be not highly flammable as it failed to ignite in the preliminary screening test. Therefore it does not meet the criteria for classification as a flammable solid as set out in 1272/2008/EC (amended).
