Reference 1

Endpoint:

flammable solids

Type of information:

experimental study

Adequacy of study:

key study

Study period:

22 March 2017 to 23 March 2017

Reliability:

1 (reliable without restriction)

Rationale for reliability incl. deficiencies:

guideline study

Reason / purpose for cross-reference:

reference to same study

Qualifier:

according to guideline

Guideline:

UN Manual of Tests and Criteria: Test N.1 (Test method for readily combustible solids)

Version / remarks:

2015

Deviations:

no

GLP compliance:

yes (incl. QA statement)

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

Remarks:

The test material shrank and glowed orange but failed to ignite or propagate combustion.

The test material shrank and glowed orange but failed to ignite or propagate combustion during the 2 minutes that the Bunsen flame was applied. The result of the preliminary screening test obviated the need to perform the definitive test.

Interpretation of results:

other: Not highly flammable in accordance with EU criteria

Conclusions:

Under the conditions of this study, the test material is not classified as a flammable solid.

Executive summary:

The flammability of the test material was investigated in accordance with the standardised guideline UN Method N.1 under GLP conditions.

The test material shrank and glowed orange but failed to ignite or propagate combustion during the 2 minutes that the Bunsen flame was applied. The result of the preliminary screening test obviated the need to perform the definitive test.

Under the conditions of this study, the test material is not classified as a flammable solid.

Reference 2

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

Justification for type of information:

JUSTIFICATION FOR DATA WAIVING
In accordance with section 1.5 of REACH Annex XI, the study does not need to be performed as based on chemical structure water reactivity is not to be expected. In addition, under conditions where neodymium trichloride is in contact with water, no ignition and/or liberation of flammable gases is observed.

Reference 3

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

Justification for type of information:

JUSTIFICATION FOR DATA WAIVING
In accordance with section 1.5 of REACH Annex XI, the study does not need to be performed as based on chemical structure pyrophoric properties are not to be expected. In addition, in the daily use and handling of the substance during which continuous exposure to air can occur, no spontaneous ignition is observed.

Description of key information

Flammability (solids)

Under the conditions of this study, the test material is not classified as a flammable solid.

Key value for chemical safety assessment

Flammability:

not classified

Additional information

Flammability (solids)

The flammability of the test material was investigated in accordance with the standardised guideline UN Method N.1 under GLP conditions. The study was awarded a reliability score of 1 in accordance with the criteria set forth by Klimisch et al. (1997).

The test material shrank and glowed orange but failed to ignite or propagate combustion during the 2 minutes that the Bunsen flame was applied. The result of the preliminary screening test obviated the need to perform the definitive test.

Under the conditions of this study, the test material is not classified as a flammable solid.

Pyrophoricity

In accordance with point 1 of Annex XI, it is considered justified to omit the testing for pyrophoric properties. Testing does not appear scientifically necessary as experience in use and experience of handling the substance indicates that it does not possess pyrophoric properties.

Flammability in contact with water

In accordance with point 1 of Annex XI, it is considered justified to omit the testing for substances or mixtures which in contact with water emit flammable gases. Testing does not appear scientifically necessary as experience in use and experience of handling the substance indicates that it does not emit flammable gases in contact with water.

Justification for classification or non-classification

In accordance with the criteria for classification as defined in Annex I, Regulation (EC) No 1272/2008, the substance does not require classification with respect to flammability.
