Endpoint:

flammable solids

Type of information:

experimental study

Adequacy of study:

key study

Study period:

29 June 2016

Reliability:

1 (reliable without restriction)

Rationale for reliability incl. deficiencies:

guideline study

Qualifier:

according to guideline

Guideline:

EU Method A.10 (Flammability (Solids))

Version / remarks:

2008

Deviations:

no

GLP compliance:

yes (incl. QA statement)

Key result

Test procedure:

burning rate test: preliminary screening test

Burning time:

24.5 min

In the first preliminary test the flame extinguished after 6 minutes and 50 seconds, in the second test the burning rate of the 200 mm powder train was 24 minutes and 30 seconds. Based on the results of the preliminary test no further testing was required.

Interpretation of results:

not classified based on GHS criteria

Conclusions:

Under the conditions of this study, the test material is considered ‘not highly flammable’.

Executive summary:

The flammability of the test material was investigated in accordance with the standardised guideline EU Method A.10 under GLP conditions.

The flame from a gas burner was applied to one end of a 200 mm powder train. The flame from a gas burner was applied to one end of the powder train until the powder ignited. The preliminary test was performed twice. In both cases the test item ignited.  In the first test the flame extinguished after 6 minutes and 50 seconds. In the second test the burning rate of the 200 mm powder train was 24 minutes and 30seconds. Based on the results of the preliminary test no further testing was required.

The test material is considered flammable if the main test takes less than 45 seconds. Therefore the substance is considered not to be highly flammable.

Description of key information

Key value for chemical safety assessment

Flammability:

not classified

Additional information

The flammability of the test material was investigated in accordance with the standardised guideline EU Method A.10 under GLP conditions. The study was awarded a reliability score of 1 in accordance with the criteria set forth by Klimisch et al. (1997).

The flame from a gas burner was applied to one end of a 200 mm powder train. The flame from a gas burner was applied to one end of the powder train until the powder ignited. The preliminary test was performed twice. In both cases the test item ignited.  In the first test the flame extinguished after 6 minutes and 50 seconds. In the second test the burning rate of the 200 mm powder train was 24 minutes and 30seconds. Based on the results of the preliminary test no further testing was required.

The test material is considered flammable if the main test takes less than 45 seconds. Therefore the substance is considered not to be highly flammable.

Pyrophoricity

In accordance with Section 1 of REACH Annex XI, the study does not need to be performed as based on chemical structure and experience in use pyrophoricity is not to be expected and hence testing does not appear scientifically necessary.

Reactivity with water

In accordance with Section 1 of REACH Annex XI, the study does not need to be performed as based on chemical structure and experience in use water reactivity is not to be expected and hence testing does not appear scientifically necessary.

Justification for classification or non-classification

In accordance with the criteria for classification as defined in Annex I, Regulation (EC) No 1272/2008, the substance does not require classification with respect to flammability.
