Reference
Endpoint:
flammable solids
Type of information:
experimental study
Adequacy of study:
key study
Study period:
23rd-24th June 1994
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
guideline study
Qualifier:
according to
Guideline:
EU Method A.10 (Flammability (Solids))
Version / remarks:
Commission Directive 92/69/EEC
Deviations:
no
GLP compliance:
yes (incl. certificate)
Key result
Test procedure:
burning rate test: preliminary screening test
Moisture (wt %):
0.282
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

Preliminary screening test:

The 'rope' ignited and burned with an orange/blue flame which emitted white smoke. The flame self-extinguished without propogating combustion.

Interpretation of results:
not classified based on GHS criteria
Conclusions:
The test item has been determined to be not highly flammable as it did not propagate combustion over the 200 mm of the preliminary screening test.
Executive summary:

The flammability of the test item was determined according to EU Method A.10 of Commission Directive 92/69/EEC. In the preliminary screening test the test item ignited and burned but the flame self-extinguished without propagating combustion. The resul of the preliminary screening test ocviated the need to perform the main test. The test item is not highly flammable.

Description of key information

The substance is not highly flammable.

Key value for chemical safety assessment

Flammability:
not classified

Additional information

The test item failed to maintain combustion in a preliminary test performed according to EU Method A.10 of Commission Directive 92/69/EEC and, therefore, is not considered to be highly flammable.

The substance is manufactured and placed on the market as an aqueous solution. From experience in use, the substance does not emit flammable gases in contact with water.

From experience in use of handling the dried substance, it is not pyrophoric.

Justification for classification or non-classification

The test item failed to maintain combustion in a preliminary test performed according to EU Method A.10 of Commission Directive 92/69/EEC and, therefore, is not considered to be highly flammable.

The substance is manufactured and placed on the market as an aqueous solution. From experience in use, the substance does not emit flammable gases in contact with water.

From experience in use of handling the dried substance, it is not pyrophoric.
