Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Endpoint:
flammable solids
Type of information:
experimental study
Adequacy of study:
key study
Study period:
07-Mar-2002
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
guideline study
Qualifier:
according to guideline
Guideline:
EU Method A.10 (Flammability (Solids))
GLP compliance:
yes (incl. QA statement)
Remarks:
The Swiss GLP Monitoring Authorities
Test procedure:
burning time over 250 mm for metal powders or metal alloys
Remarks:
the substance is not a metal powder of a metal alloy, but the test was the same.
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

Results

The test item could not be ignited with a flame during the preliminary test (contact time of about 2 minutes). In contact with the ignition source, the test item melted and evolved white smoke. A yellowish to brown, clear melt remained. Therefore, no main test was performed.

In conclusion, the test item is not flammable according to the criteria of the guideline.

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 experience in production or handling shows that the substance does not react with water, e.g. the substance is manufactured with water or washed with water
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
Endpoint:
self-heating substances / mixtures
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 completely molten at 160°C

Description of key information

not flammable
no pyrophoricity
no flammability on contact with water

no self-heating

Key value for chemical safety assessment

Flammability:
not classified

Additional information

Based on the flammability result, the test substance is a non flammable solid.

Based on experience in handling and use and the chemical structure, pyrophoricity, flammability on contact with water and self-heating are not to be expected.

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:

No propagation of burning in a test according to EU Method A.10.

Based on the chemical structure and experience in handling and use, pyrophoricity and flammability on contact with water are not expected.

The substance is completely molten at 160 °C and therefore does not show self-heating behaviour.
