key study

Study period:

2007-11-07

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:

1992

Deviations:

no

GLP compliance:

yes (incl. QA statement)

Remarks:

issued 2003-04-29

Key result

Test procedure:

burning rate test: preliminary screening test

Burning time:

> 120 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

A Pre-test was conducted : ignition did not occur within 2 minutes of heating using a teclu gas burner. Melting and change of colour from light yellow to black were observed. A combustion with flame of the test item did not propagate within the test period of 4 minutes. Therefore the test item is considered as not highly flammable. No further testing was carried out.

Interpretation of results:

not classified based on GHS criteria

Conclusions:

The study was conducted in accordance with EC Method A.10. As a result of the pre-test, ignition of the test item using a teclu burner did not occur within 2 minutes. Melting and change of colour from light yellow to black were observed. A combustion with flame of the test item did not propagate within the test period of 4 minutes. Therefore the test item is considered as not highly flammable.

Endpoint:

substances / mixtures which in contact with water emit flammable gases

Type of information:

other: expert judgement

Adequacy of study:

key study

Study period:

2006

Reliability:

2 (reliable with restrictions)

Rationale for reliability incl. deficiencies:

other: Expert judgement reliable with restrictions.

Qualifier:

no guideline followed

Principles of method if other than guideline:

The experimental test to determine whether the reaction of a substance with water or damp air leads to the development of dangerous amounts of gas or gases, which may be highly flammble, according to the EU method A.12 was replaced by a theory based evaluation.

GLP compliance:

not specified

Key result

Test procedure:

ignition time on contact with air

Remarks on result:

no ignition on contact with air (not further specified)

Remarks:

expert judgement

The chemical structure of the test item does not contain chemical groups capable of causing the development of a dangerous amount of flammable gas, when getting in contact with damp air or water. Therefore, the test item is not considered as highly flammable.

Interpretation of results:

GHS criteria not met

Conclusions:

The chemical structure of the test item does not contain chemical groups capable of causing the development of a dangerous amount of flammable gas, when getting in contact with damp air or water.

Description of key information

Based on the preliminary test, no ignition of the powder took place; the solid substance is considered as not flammable. Method: EC Method A.10 (1992).

With regards to Flammability (contact with water) the chemical structure of the test item does not contain chemical groups capable of causing the development of a dangerous amount of flammable gas, when getting in contact with damp air or water. Therefore, the test item is not considered as highly flammable. Method: Expert jugdement in accordance to EC Method A.12 (1992)

Key value for chemical safety assessment

Flammability:
