Endpoint:

flammable solids

Type of information:

experimental study

Adequacy of study:

key study

Reliability:

2 (reliable with restrictions)

Rationale for reliability incl. deficiencies:

other: Non-GLP but proprietary study.

Reason / purpose for cross-reference:

reference to same study

Reason / purpose for cross-reference:

reference to other study

Qualifier:

according to guideline

Guideline:

EU Method A.10 (Flammability (Solids))

GLP compliance:

not specified

Test procedure:

burning rate test: preliminary screening test

Remarks on result:

other: The test material could not be ignited with a flame because it decomposed during the heating.

A preliminary test was performed to determine if the main test needs to be performed.

When the pile was ignited and burned over a distance of 200 mm during 4 minutes, the test has to be performed. However, if there was no ignition of the test item or the pile burned slower than 200 mm during 4 minutes, the main test is unnecessary.

The test item could not be ignited with a flame because it decomposed during the heating. The colour of the test item changed from dark violet to grayish. Consequently, the main test was not necessary.

Interpretation of results:

other: Not classified according to EU criteria.

Conclusions:

The test item could not be ignited with a flame because it decomposed during the heating. The colour of the test item changed from dark violet to grayish. Consequently, the main test was not necessary.
It can be concluded that the test item is not a highly flammable solid.

Executive summary:

The test item could not be ignited with a flame because it decomposed during the heating. The colour of the test item changed from dark violet to grayish. Consequently, the main test was not necessary.

It can be concluded that the test item is not a highly flammable solid.

Description of key information

CBW (2009)

The test material could not be ignited with a flame because it decomposed during the heating. The colour of the test material changed from dark violet to grayish. Consequently, the main test was not necessary.

It can be concluded that the test material is not a highly flammable solid.

 

Pyrophoric Properties

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.

 

Flammability on Contact with Water

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.

Key value for chemical safety assessment

Flammability:

not classified

Additional information

The test material could not be ignited with a flame because it decomposed during the heating. The colour of the test material changed from dark violet to grayish. Consequently, the main test was not necessary.  The study was awarded a reliability score of 2 in accordance with the criteria set forth by Klimisch et al. (1997).

It can be concluded that the test material is not a highly flammable solid.

Justification for classification or non-classification

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