Reference 1

Endpoint:

flammable solids

Type of information:

experimental study

Adequacy of study:

key study

Study period:

5 October 2006 - 12 January 2007

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:

December 1992

Deviations:

no

GLP compliance:

yes (incl. QA statement)

Key result

Test procedure:

burning rate test over 100 mm length

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

Interpretation of results:

not classified based on GHS criteria

Conclusions:

The flame of a gas burner ignited the test substance pile. In contact with the flame the test substance melted. The test substance turned black. After removal of the ignition source no propagation of combustion was observed. Because no burning with flame or smouldering over 200 mm within 4 minutes was observed, the substance is considered not highly flammable.

Endpoint:

substances / mixtures which in contact with water emit flammable gases

Type of information:

other: expert statement

Adequacy of study:

supporting study

Study period:

5 October 2006 - 12 January 2007

Reliability:

2 (reliable with restrictions)

Rationale for reliability incl. deficiencies:

study well documented, meets generally accepted scientific principles, acceptable for assessment

Qualifier:

according to guideline

Guideline:

EU Method A.12 (Flammability (Contact with Water))

Version / remarks:

December 1992

Deviations:

no

GLP compliance:

yes (incl. QA statement)

Remarks on result:

not measured/tested

Remarks:

expert statement only

Interpretation of results:

not classified based on GHS criteria

Conclusions:

A test substance is considered highly flammable when it ignites spontaneously when coming into contact with water or damp air, or evolves flammable gas at a rate >1 L/kg of test substance per hour.
The structure of the substance does not contain groups that might lead to the evolution of a dangerous amount of flammable gas when coming into contact with water or damp air.
In conclusion, the substance is not highly flammable in contact with water or damp air.

Endpoint:

pyrophoric solids

Type of information:

Adequacy of study:

key study

Study period:

5 October 2006 - 12 January 2007

Reliability:

1 (reliable without restriction)

Rationale for reliability incl. deficiencies:

guideline study

Qualifier:

according to guideline

Guideline:

EU Method A.13 (Pyrophoric Properties of Solids and Liquids)

Version / remarks:

December 1992

Deviations:

no

GLP compliance:

yes (incl. QA statement)

Key result

Test procedure:

ignition time on contact with air

Temp.:

20 °C

Remarks on result:

no ignition within 5 minutes

Interpretation of results:

not classified based on GHS criteria

Conclusions:

In none of the six tests, where approx. 2 ml (between 1.366 and 1.381 g) of the test substance was poured from a height of 1 meter onto a non-combustible solid surface, spontaneous ignition of the test substance occurred during dropping or within five minutes of settling. Based on these results, the substance does not need to be classified as pyrophoric.

Description of key information

Flammability solids:

The flame of a gas burner ignited the test substance pile. In contact with the flame the test substance melted. The test substance turned black. After removal of the ignition source no propagation of combustion was observed. Because no burning with flame or smouldering over 200 mm within 4 minutes was observed, the substance is considered not highly flammable.

Flammability in contact with water:

A test substance is considered highly flammable when it ignites spontaneously when coming into contact with water or damp air, or evolves flammable gas at a rate >1 L/kg of test substance per hour.

The structure of the substance does not contain groups that might lead to the evolution of a dangerous amount of flammable gas when coming into contact with water or damp air.

In conclusion, the substance is not highly flammable in contact with water or damp air.

Pyrophoric properties:

In none of the six tests, where approx. 2 ml (between 1.366 and 1.381 g) of the test substance was poured from a height of 1 meter onto a non-combustible solid surface, spontaneous ignition of the test substance occurred during dropping or within five minutes of settling. Based on these results, the substance does not need to be classified as pyrophoric.
