- Interpretation of results:
- not classified based on GHS criteria
- Remarks:
- The test item melted quickly and failed to ignite during the 2 minutes that the ignition source was applied.
- Conclusions:

- Executive summary:
EU Methods A.10. – The flammability of the test item was determined using procedures designed to be compatible with Method A.10., Flammability (Solids), of Commission Regulation (EC) No 440/2008 of 30 May 2008.
The test item was loosely filled into a mould as described in the guideline. A non-combustible and non-porous plate was placed on top of the mould, the apparatus inverted, and the mould removed. The test was started by trying to ignite the pile at one end over a period of 2 minutes.
After 2 minutes the flame was removed from the test item. The pile melted quickly and failed to ignite during the 2 minutes that the Bunsen flame was applied.
The test item cannot be classified as flammable in accordance with Commission Regulation (EC) No 1272/2008 (Classification Labelling and Packaging) of 16 December 2008.
- 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
Assessment under REACH Annex XI section 1.2 indicates an absence of pyrophoricity. - 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 organic substance does not contain metals or metalloids and hence, the classification procedure does not need to be applied
- the study does not need to be conducted because the substance is known to be soluble in water to form a stable mixture
- Justification for type of information:
- JUSTIFICATION FOR DATA WAIVING
Assessment under REACH Annex XI section 1.2 indicates absence of contact with water resulting in the emission of flammable gases.

Evaluation of Data:
The burning times are expressed in seconds.
The test item is considered highly flammable when in one of the definitive tests carried out according to the outlined test procedure the burning time is less than 45 seconds over a distance of 100 mm. Powders of metals or metal-alloys are considered to be highly flammable if they can be ignited and the flame or the zone of reaction spreads over the whole sample.
If the test item does not ignite and propagate combustion either by burning with a flame or smoldering along 200 mm within 4 minutes, the test item is not considered as highly flammable and no further testing is required.
Results - Preliminary Screening Test:
The pile melted quickly and failed to ignite during the 2 minutes that the Bunsen flame was applied.
The result of the preliminary screening test obviated the need to perform the main test.

Pyrophoricity and Flammability in Contact with Water – In accordance with Annex XI, Section 1.2 of the REACH Regulation the flammability endpoint, comprising flammable solids, pyrophoric solids and substances which in contact with water emit flammable gases, may be completed based on weight of available evidence. The substance has been experimentally determined as non-flammable following a study conducted according to EU Method A.10 (flammable solids).
A review of the structure of test item constituents and the physical properties of the test item imply no pyrophoric properties or flammability on contact with water. Based on experience of handling and use of the test item, neither pyrophoric properties nor flammability of contact with water are expected to be properties associated with this test item.
