Administrative data
Link to relevant study record(s)
- Endpoint:
- flammable solids
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 29 April 2003 - 9 May 2003
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- equivalent or similar to guideline
- Guideline:
- EU Method A.10 (Flammability (Solids))
- Version / remarks:
- The fire train test was performed in accordance with SOP, LP-06. Method used is based on EU method A.10
- Deviations:
- no
- GLP compliance:
- yes (incl. QA statement)
- Specific details on test material used for the study:
- Moisture content: 0.5% w/w
Batch Number: H03421 - Test procedure:
- burning rate test over 100 mm length
- Burning time:
- 0 s
- Moisture (wt %):
- 0.5
- Remarks on result:
- other: combustion localised to ignition source
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- Substance is non-combustible
- Executive summary:
Flammability of thioacid was evaluated through a train fire test, based on EU method A.10 (Official Journal of the European Communities L383). A sample of the material was supplied by GlaxoSmithKline for the purposes of this test. The test concluded that the material is classified as a non-combustible solid and will not support propagating combustion. It can support combustion in the vicinity of a very hot ignition source.
Reference
Six fire train tests were performed on the test substance at room temperature (21°C). The fire did not propagate along the train during this test. The substance was observed to support localised combustion.
Test 1: No burning observed
Test 2: No burning observed
Test 3: No burning observed
Test 4: No burning observed
Test 5: No burning observed
Test 6: No burning observed
Description of key information
Flammability of thioacid was evaluated through a train fire test, based on EU method A.10 (Official Journal of the European Communities L383). The test concluded that the material is classified as a non-combustible solid and will not support propagating combustion.
Key value for chemical safety assessment
- Flammability:
- not classified
Additional information
Justification for classification or non-classification
A train fire (10 cm) test, based on EU method A.10 under GLP conditions, concluded that it is non-combustible and will not propagate ignition. The test substance supported localised combustion but flame propagation was not observed during the tests, so the criteria for classification as a flammable solid (section 2.7.2 of Annex I of CLP) are not fulfilled.
