Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Qualifier:
according to guideline
Guideline:
UN Manual of Tests and Criteria: Test N.1 (Test method for readily combustible solids)
Qualifier:
according to guideline
Guideline:
EU Method A.10 (Flammability (Solids))
Version / remarks:
(EC) No. 440/2008
GLP compliance:
no
Key result
Test procedure:
burning rate test: preliminary screening test
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

Screening test

In contact with a hot flame of a small gas burner the substance cannot be ignited (burning number BZ = 1). The test has been repeated six times. The full burning rate test is therefore not required.

Interpretation of results:
not classified based on GHS criteria
Conclusions:
The test item does not have to be considered as a flammable solid and a full burning rate test is not necessary.
Executive summary:

According to the burning rate test N.1 of the UNRTDG, GHS Regulation (EC) No 1272/2008 and Council Regulation (EC) No 440/2008 test A.10, the test item is not a flammable solid of Division 4.1 and does not have be labelled as such a substance since it cannot be ignited by a hot flame of a small gas burner.

Description of key information

The test item is not a flammable solid.

Key value for chemical safety assessment

Flammability:
not classified
