Flammability
Administrative data
Link to relevant study record(s)
- Endpoint:
- flammable solids
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- from 18 feb 2010 to 13 apr 2010
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- other: This study was carried out following an internationally recognized guideline and in accordance with GLP. Furthermore, the substance identity is fully described.
- Reason / purpose for cross-reference:
- reference to same study
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.10 (Flammability (Solids))
- Deviations:
- no
- GLP compliance:
- yes (incl. QA statement)
- Interpretation of results:
- not classified based on GHS criteria
- Conclusions:
- The test item was not considered as highly flammable under these experimental conditions.
- Executive summary:
In a study (Defitraces 2010), Catechol was evaluated for its flammability, following A10 method and according to GLP.
In the preliminary assay of this study, the test item melted under the flame and made a brown liquid which spread out. Neither ignition, nor propagation was observed. This result was observed twice.
Taking into account the results obtained during the preliminary test, no main test was performed.
In these conditions, Catechol was not considered as highly flammable.
Reference
Preliminary test
Assay No. 1
The test item melted under the flame and made a brown liquid which spread out. Neither ignition, nor propagation was observed.
Assay No. 2
The same observations as for the assay No. 1 were recorded.
Main test
Taking into account the results obtained during the preliminary test, no main test was performed.
Description of key information
Catechol is not highly flammable.
Key value for chemical safety assessment
- Flammability:
- non flammable
Additional information
Flammability
One study dealing with catechol flammability is available. As an internationally recognized guideline was followed and the GLP were stated, this study of reliability 1 according to Klimisch was selected as a key study.
Flammability in contact with water & Pyrophoricity
These endpoints are waived based on the absence of structural chemical alerts.
Justification for classification or non-classification
Catechol is non flammable when tested according to the A10 method. Hence, it is not classified under CLP criteria.
