Type of information:
experimental study
Adequacy of study:
key study
Study period:
11 July - 20 July 2018
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
guideline study
according to guideline
EU Method A.10 (Flammability (Solids))
GLP compliance:
yes (incl. QA statement)
Specific details on test material used for the study:
- Test material: Balsalazide acid
- Batch number: 0400
- Expiry date: April 2019
- Storage: Room temperature
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

Two preliminary tests were performed and the same sample behaviour was observed.

The test item did not ignite but the solid sample initially carbonised when the Bunsen burner flame came close.

Since the test item did not propagate combustion, no further testing was required.

Interpretation of results:
not classified based on GHS criteria
Balsalazide acid is not a highly flammable substance.

Description of key information

The flammability of the test item, Balsalazide acid was determined according to EC Method A.10 and was found to be not flammable.

Key value for chemical safety assessment

not classified

Additional information

Justification for classification or non-classification

Balsalazide acid did not propagate combustion in the test. Therefore, it can be concluded that the test material is not a highly flammable substance.
