Rationale for reliability incl. deficiencies:

guideline study

Qualifier:

according to guideline

Guideline:

EU Method A.10 (Flammability (Solids))

Version / remarks:

31 May 2008

Deviations:

no

GLP compliance:

yes (incl. QA statement)

Specific details on test material used for the study:

Storage conditions: Controlled room temperature (15-25 ℃, below 70RH %)

Key result

Test procedure:

burning rate test: preliminary screening test

Remarks on result:

other: The test material could not be ignited in less than 45 seconds.

In the preliminary test the test material could not be ignited. Based on the results of the preliminary test, no main test was performed.

Interpretation of results:

other: Not classified according s highly flammable according to EU criteria

Conclusions:

Under the conditions of the study, the test material is considered not to be 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.

In the preliminary test the flame from a gas burner was applied to one end of the powder train until the powder ignited. The test was performed two times. The test material melted but it did not ignite. Based on the results of the preliminary test, no main test was performed.

Under the conditions of this study, the test material is considered not to be highly flammable. 

Reference 2

Endpoint:

substances / mixtures which in contact with water emit flammable gases

Data waiving:

study scientifically not necessary / other information available

Justification for data waiving:

the study does not need to be conducted because the experience in production or handling shows that the substance does not react with water, e.g. the substance is manufactured with water or washed with water

Justification for type of information:

JUSTIFICATION FOR DATA WAIVING
In accordance with section 1.5 of REACH Annex XI, the study does not need to be performed as based on chemical structure water reactivity is not to be expected.

Reference 3

Endpoint:

pyrophoric solids

Data waiving:

study scientifically not necessary / other information available

Justification for data waiving:

the study does not need to be conducted because the substance is known to be stable in contact with air at room temperature for prolonged periods of time (days) and hence, the classification procedure does not need to be applied

Justification for type of information:

JUSTIFICATION FOR DATA WAIVING
In accordance with section 1.5 of REACH Annex XI, the study does not need to be performed as based on chemical structure pyrophoric properties are not to be expected.

Description of key information

The test material is considered not to be highly flammable. 

Key value for chemical safety assessment

Flammability:

not classified

Additional information

Flammability (solids)

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).

In the preliminary test the flame from a gas burner was applied to one end of the powder train until the powder ignited. The test was performed two times. The test material melted but it did not ignite. Based on the results of the preliminary test, no main test was performed.

Under the conditions of this study, the test material is considered not to be highly flammable. 

Flammability (pyrophoric solids)

In accordance with point 1 of REACH Annex XI, it is considered justified to omit the testing for pyrophoric properties. Testing does not appear scientifically necessary as in the daily use and handling of the test material, during which continuous exposure to air can occur, no spontaneous ignition is observed. The absence of structural alerts furthermore confirms that it is highly unlikely that the test material possesses pyrophoric properties.

Flammability (substances / mixtures which in contact with water emit flammable gases)

In accordance with point 1 of REACH Annex XI, it is considered justified to omit the testing for substances or mixtures which in contact with water emit flammable gases. Testing does not appear scientifically necessary as under conditions where the test material is in contact with water, no ignition and/or liberation of flammable gases is observed. The absence of structural alerts furthermore confirms that it is highly unlikely that the test material is flammable in contact with water.

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.
