Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Preliminary test: the test substance did not propagate combustion beyond the first timing mark and no burning times could be recorded.

full stest series: no required

Interpretation of results:
other: non flammable
Conclusions:
The test substance did not propagate combustion.
The test substance is not classified as highly flammable in terms of its burning characteristics.

step 1 - no gas evolved

step 2 - no gas evolved

step 3 - no gas evolved

step 4 - Sample preparation: tested as received

Room temperature: 20°C-21°C

Water temperature: 21°C-22°C

No gas was evolved on contact with water over a period of 7 hours in each of the three tests.

Interpretation of results:
other: non flammable
Conclusions:
The test substance does not evolve highly flammable gases on contact with water.
The test substance is not classified as highly flammable in terms of its reactivity with water.

GLP compliance:
yes (incl. QA statement)

Room temperature: 19°C

No sign of ignition were observed in any of the six tests.

Interpretation of results:
other: non flammable
Conclusions:
The test substance does not spontaneusly ignite on contact with air at ambient temperatures.
The test substance is not classified as higlhy flammable in terms of pyrophoric properties.

Description of key information

Non flammable

Key value for chemical safety assessment

Flammability:
non flammable

Additional information

Three test are available on the substance (Stahl, 1996).

The first test, following the guideline A10, shows that the test substance does not meet the criteria for classification in terms of its burning characteristics.

The second test, following the guideline A12, shows that the test substance does not evolve higlhy flammable gases in dangerous quantities on contact with water.

The third test, following the guideline A13, shows that the tes substance does not ignite on contact with air at ambient temperature.

Therefore, the substance can be considered as non flammable.

Justification for classification or non-classification

Based on the tets results, the substance does not meet the criteria for classification in terms of its burning characteristics, does not evolve higlhy flammable gases in dangerous quantities on contact with water. and does not ignite on contact with air at ambient temperature.

Therofore, no classification for flammability has been warranted under EC 1272/2008.
