Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Flammability
Administrative data
Link to relevant study record(s)
- 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:
- other:
- Endpoint:
- flammable solids
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- other: GLP-Guideline study
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.10 (Flammability (Solids))
- Deviations:
- yes
- Remarks:
- Ignition source: platinum wire heated by electrical powder (current 30A, about 1000 °C), instead a direct flame as proposed in the guideline. This modification has no effect on the conclusion.
- GLP compliance:
- yes
- Test procedure:
- burning rate test: preliminary screening test
- Remarks on result:
- other: substance does not ignite
- Endpoint:
- flammable solids
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 17 Feb 2009
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- other: GLP - Guideline study
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.10 (Flammability (Solids))
- Deviations:
- no
- GLP compliance:
- yes (incl. QA statement)
- Remarks:
- Landesamt für Umwelt, Wasserwirtschaft und Gewerbeaufsicht, Kaiser-Friedrich-Straße 7, 55116 Mainz, Germany
- Test procedure:
- burning rate test: preliminary screening test
- Remarks on result:
- other: Substance developed a yellow flame. Glowing was observed, too. The test item’s colour changed to black where it came in contact with the flame of the gas burner. No ignition took place within two minutes, the flame died when the burner was taken away.
Referenceopen allclose all
The test item did not burn. No further testing was required.
Lanthanum carbonate is not "highly flammable" under the conditions of the test.
Preliminary screening test:
It was observed that the substance developed a yellow flame. Glowing was observed, too. The test item’s colour changed to black where it came in contact with the flame of the gas burner. No ignition took place within two minutes, the flame died when the burner was taken away.
Determination of burning rate:
Determination of burning rate was not carried out, as no ignition was observed in the screening test.
Result:
The test item Dilanthanum tricarbonate should be considered as not highly flammable.
No observations were made which might cause doubts concerning the validity of the study outcome.
Description of key information
No flammability on ignition (Preliminary test, EU Method A.10)
No pyrophoricity.
Not self-heating.
No flammability on contact with water.
Key value for chemical safety assessment
- Flammability:
- not classified
Additional information
Two study reports are available, which investigated the flammability of Lanthanum carbonate according to EU method A.10 (Paulus 2009, Cerrutti 2005). The tests showed that no ignition took place within two minutes, the flame died when the burner was taken away. So the test item should be considered as not highly flammable.
Justification for classification or non-classification
The available data on oxidising properties 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 flammability on ignition (Preliminary test, EU Method A.10)
No pyrophoricity.
Not self-heating.
No flammability on contact with water.
