The following total quantities of liberated gas were determined by using a miniature gasometer.

	Trial 1	Trial 2	Trial 3
test sample weights	10.0 g	10.0 g	10.0 g
time	total quantities of liberated gas
60 min	0 L/kg*h	0 L/kg*h	0 L/kg*h
120min	0 L/kg*h	0 L/kg*h	0 L/kg*h
180min	0 L/kg*h	0 L/kg*h	0 L/kg*h
240 min	0 L/kg*h	0 L/kg*h	0 L/kg*h

360 min	0 L/kg*h	0 L/kg*h	0 L/kg*h
420 min	0 L/kg*h	0 L/kg*h	0 L/kg*h

Liberation of gas could be observed in one of three trials after water addition was initiated. The gas production based on one kilogram of test substance and a one-hour test period was considerably less than 1 L/(kg*h) in all trials. An analysis of the reaction products within the scope of this investigation was omitted.

The test item does not liberate gases in hazardous amounts when tested according to this procedure. The substance does not emit flammable gases on contact with water.

Interpretation of results:

not classified based on GHS criteria

Endpoint:

flammable solids

Type of information:

experimental study

Adequacy of study:

key study

Study period:

Nov 30 1995 - Dec 5 1995

Reliability:

1 (reliable without restriction)

Qualifier:

according to guideline

Guideline:

EU Method A.10 (Flammability (Solids))

GLP compliance:

yes

The test substance melted when approached by the ignition flame. No flame propagation was observed. The test was repeated twice. No further testing was required.

The test item is accordingly classified as not highly flammable when tested according to the above procedure.

Interpretation of results:

not classified based on GHS criteria

Endpoint:

pyrophoric solids

Type of information:

experimental study

Adequacy of study:

key study

Study period:

Nov 30 1995 - Dec 5 1995

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)

GLP compliance:

yes

The substance dropped down from a height of 1 m onto a ceramic plate. Neither during drop down nor within the following 5 minutes an inflammation could be registrated. The test was repeated five times.

The test item has no pyrophoric property in the sense of this test procedure.

Interpretation of results:

not classified based on GHS criteria

Description of key information

Non flammable solid (EU Method A.10)

No flammability on contact with water (EU Method A.12)

No pyrophoricity (EU Method A.13)

Not self-heating (Melting point < 160 °C)

Key value for chemical safety assessment

Flammability:

not classified

Additional information

The test substance melted when approached by the ignition flame; no flame propagation was observed.

The substance does not emit flammable gases on contact with water.

The test item has no pyrophoric property in the sense of the test procedure.

The substance has a melting point of 78.7-79.7°C; the determination of self-heating behaviour is not relevant for substances that are completely molten at 160°C.

Justification for classification or non-classification

The available data on flammability of the test substance do not meet the criteria for classification according to Regulation (EC) 1272/2008, and are therefore conclusive but not sufficient for classification:

The test substance melted when approached by the ignition flame; no flame propagation was observed (EU Method A.10).

The substance does not emit flammable gases on contact with water (EU Method A.12).

The test item has no pyrophoric property in the sense of the test procedure (EU Method A.13).

The substance has a melting point of 78.7-79.7°C; the determination of self-heating behaviour is not relevant for substances that are completely molten at 160°C.
