key study
Study period:
01 July 2019 to 01 July 2019
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
guideline study
Qualifier:
according to guideline
Guideline:
EU Method A.10 (Flammability (Solids))
Deviations:
no
GLP compliance:
yes (incl. QA statement)
Specific details on test material used for the study:
No further details specified in the study report
Key result
Test procedure:
burning rate test: preliminary screening test
Burning time:
2 min
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

In the preliminary tests the test item melted. The molten test item flamed for 1-2 seconds, but did not propagate further, then the flame extinguished itself.

Based on the results of the preliminary tests, no main test was performed.

Interpretation of results:
not classified based on GHS criteria
Conclusions:
The molten test item flamed for 1-2 seconds, but did not propagate. Therefore, the test item is considered to be non-flammable.
Executive summary:

The flammability of test item CAS 577978-76-8 was carried out in accordance with test guideline EU A.10, in compliance with GLP.

Two parallel flammability tests were performed. The tests were negative.

The test item (CAS 577978-76-8) is considered to be non-flammable under the conditions of this test.

Description of key information

The molten test item flamed for 1-2 seconds, but did not propagate. Therefore, the test item is considered to be non-flammable.

Key value for chemical safety assessment

Flammability:
not classified

Additional information

Justification for classification or non-classification

The molten test item flamed for 1-2 seconds, but did not propagate. Therefore, the test item is considered to be non-flammable.
