Key result

Test procedure:

burning rate test: preliminary screening test

Burning time:

0 s

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

The test substance could not be ignited with a flame, under the conditions of the test. The test substance did not burn. In contact with the ignition source (the flame of a gas burner) the white colour of the test substance changed into a light grey. No further testing is required.

In conclusion, the test substance has not to be classified "highly flammable" according to the criteria in the method A.10 of EEC-Directive 84/449/EEC.

Interpretation of results:

not classified based on GHS criteria

Remarks:

Criteria used for interpretation of results: Regulation (EC) No 1272/2008 (EU GHS)

Conclusions:

Non flammable

Additional information

The flammability of substance "reaction mass of calcium hydrogen phosphonate and dialuminium hexaoxide" (a.i. 90 %) was measured in a study according to EU Method A.10 (Flammability (Solids)), 1984. The test substance could not be ignited with a flame under the conditions of the test. The test substance did not burn. In contact with the ignition source (the flame of a gas burner) the white colour of the test substance changed into a light grey. In conclusion, the test substance has not to be classified "highly flammable" according to the criteria laid down in EU method A.10 of EEC-Directive 84/449/EEC. Long-time industrial experience in manufacture and handling shows that the substance is neither pyrophoric nor releases flammable gas in contact with water.

Justification for classification or non-classification

Substance "reaction mass of calcium hydrogen phosphonate and dialuminium hexaoxide" a.i. 90 %) was determined to be non flammable under the conditions of a test according to EU Method A.10 (Flammability (Solids)), 1984. Long-time industrial experience in manufacture and handling shows that the substance is neither pyrophoric nor releases flammable gas in contact with water. In accordance with CLP Regulation (EC) No 1272/2008, substance "reaction mass of calcium hydrogen phosphonate and dialuminium hexaoxide" (a.i. 90 %) is not classified for flammability, pyrophoric properties or emission of flammable gases in contact with water and labelling is not required.
