Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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:
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:
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 substance is known to be soluble in water to form a stable mixture
Endpoint:
flammable solids
Type of information:
experimental study
Adequacy of study:
key study
Study period:
12.06.2012-16.08.2012
Reliability:
1 (reliable without restriction)
Qualifier:
according to guideline
Guideline:
EU Method A.10 (Flammability (Solids))
GLP compliance:
no
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
Interpretation of results:
GHS criteria not met
Conclusions:
Not highly flammable
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

Flammability


EU method A.10: The test item is not considered a flammable solid. Thus test item has not to be classified according to EU GHS criteria.


Flammability_self heating substances


The study is scientifically not necessary, because the substance is completely molten at 160°C.


Flammability, contact with water


The study is scientifically not necessary, because the substance is known to be soluble in water to form a stable mixture.


Flammability, pyrophoric solids


The study is scientifically not necessary, because the substance is known to be stable in contact with air at room temperature for prolonged periods of time (days) and the test material does not contain structural components associated with pyrophoricity mentioned in the Guidance on information requirements and chemical safety assessment Chapter R.7a: Endpoint specific guidance, chapter R.7.1.10.3, page 123. Therefore, it can be concluded that the test material exhibit no risk for pyrophoricity.


 

Key value for chemical safety assessment

Flammability:
not classified

Additional information

Dehydrated sample of EP1-Na (produced by adding aqueous NaOH to EP1-Na)

Justification for classification or non-classification

The test substance is not a readily combustible solid in the sense of Regulation (EC) No. 440/2008, Method A.10 and Regulation (EC) No. 1272/2008.


Based on the physical state, the structural elements and the melting point the substance has neither to be classified as flammable in contact with air, nor as pyrophoric solid, nor as self-heating substance.
