The test item does not emit any gas when brought into contact with water in any of the three tests conducted as part of Step 4.

Interpretation of results:
not classified based on GHS criteria
Remarks:
The test item did not emit any gas in contact with water during any of the 4 steps of the test procedure.
Conclusions:
The test item is not flammable in contact with water based on GHS/CLP criteria at the time of submission.
Executive summary:

EU Methods A.12. – The flammability of the test item in contact with water and the pyrophoric properties of the test item were determined using a procedure designed to be compatible with Method A.12. Flammability (Contact with Water) of Commission Regulation (EC) No 440/2008 of 30 May 2008.

Increasing quantities of test item were brought in to contact with water in a prescribed and stepwise manner.  Following each introduction of test item and water, it was noted whether (i) any gas was evolved and (ii) if ignition of the gas occurred.

The test item did not emit any gas in contact with water.

The test item does not need to be categorised in accordance with Commission Regulation (EC) No 1272/2008 (Classification Labelling and Packaging) of 16 December 2008.

Interpretation of results:
not classified based on GHS criteria
Remarks:
The test item did not ignite in contact with air during either step of the test procedure.
Conclusions:
The test item does not have pyrophoric properties.
Executive summary:

EU Methods A.13. – The pyrophoric properties of the test item were determined using a procedure designed to be compatible with Method A.13. Pyrophoric Properties of Solids and Liquids of Commission Regulation (EC) No 440/2008 of 30 May 2008.

An aliquot (approximately 5 cm3) of test item was poured onto a kieselguhr (height 5 mm) and it was observed whether the test item ignited within five minutes. The test was performed at ambient temperature six times.  If no ignition a fresh aliquot (approximately 5 ml) was added to an indented filter paper.  It was observed whether ignition or charring of the filter paper occurred within five minutes of the liquid being added. The test was performed at ambient temperature three times unless ignition or charring occurred.

The test item did not ignite when exposed air when in contact with either kieselguhr or filter paper.

The test item cannot be categorised in accordance with Commission Regulation (EC) No 1272/2008 (Classification Labelling and Packaging) of 16 December 2008.

Endpoint:

Additional information

EU Methods A.12. and A.13. – The flammability of the test item in contact with water and the pyrophoric properties of the test item were determined using procedures designed to be compatible with Method A.12. Flammability (Contact with Water) and A.13. Pyrophoric Properties of Solids and Liquids of Commission Regulation (EC) No 440/2008 of 30 May 2008.

EU Method A.12.:  Increasing quantities of test item were brought into contact with water in a prescribed and stepwise manner.  Following each introduction of test item and water, it was noted whether (i) any gas was evolved and (ii) if ignition of the gas occurred.

The test item did not emit any gas in contact with water.

EU Method A.13.: An aliquot (approximately 5 cm3) of test item was poured onto a kieselguhr (height 5 mm) and it was observed whether the test item ignited within five minutes. The test was performed at ambient temperature six times.  If no ignition a fresh aliquot (approximately 5 ml) was added to an indented filter paper.  It was observed whether ignition or charring of the filter paper occurred within five minutes of the liquid being added. The test was performed at ambient temperature three times unless ignition or charring occurred.

The test item did not ignite when exposed air when in contact with either kieselguhr or filter paper.

The test item does not need to be categorised in accordance with Commission Regulation (EC) No 1272/2008 (Classification Labelling and Packaging) of 16 December 2008.

Justification for classification or non-classification

The flammability classification of liquid test items is determined on the basis of flash point in accordance with the criteria defined i n Section 2.6.2., Annex II of Regulation (EC) 1272/2008 of 16 December 2008. As the test item has a flash point > 60 oC, it does not meet the classification criteria for classification as a flammable liquid.

Further, the test item was subject to further testing in accordance with test guideline methods EU A.12. and EU A.13.. The test item does not emit any flammable gas when brought in to contact with water or ignite when brought in to contact with air.
