Administrative data
Link to relevant study record(s)
- Endpoint:
- flammable solids
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 2011
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- 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)
- Test procedure:
- burning time (test type not further specified)
- Remarks:
- or specified in description of method (migrated information)
- Burning time:
- ca. 0 s
- Remarks on result:
- other: The test item has melted and formed a brown liquid that evaporates
- Interpretation of results:
- non flammable
- Conclusions:
- The flammability of 1,3-diortholyl guanidine (DOTG) was performed in a study performed in accordance with EC regulation 440/2008 EC A 10 method. Twice prelimary tests are performed, no main test is made. The 1,3-diortholyl guanidine (DOTG) is considered as not highly flammable under our experimental conditions.
- Executive summary:
Twice assay of flamability are made, twice with the same conclusion: at the start of the test, the test item was a white powder with agglomerates. The test item melted and turned into a beige to clear brown liquid and blackened. Neither ignition, nor propagation was observed.
Reference
Preliminary test:
4.1.1. Experimental conditions
Humidity About 27%
Room temperature About 23 °C
Atmospheric pressure 97.9 kPa
4.1.2. Assay No. 1
The test item has melted and formed a brown liquid that evaporates.
4.1.3. 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
The flammability of DOTG (1,3-d ortho tolylguaninide) was performed in a study performed in accordance with EC regulation 440/2008 EC A 10 method. Twice prelimary tests are performed, no main test is made. DOTG is considered as not highly flammable under our experimental conditions: since the product turns brown but no propoagation occured.
Key value for chemical safety assessment
- Flammability:
- non flammable
Additional information
Two assay of flammability are made by Tieche (DEFITRACE) in 2010 according to EC A10, twice with the same conclusion: at the start of the test, the test item was a white powder with agglomerates. The test item melted and turned into a beige to clear brown liquid and blackened. Neither ignition, nor propagation was observed.
Justification for classification or non-classification
The flammability of DOTG was performed in accordance with EC regulation 440/2008 EC A 10 method. Twice preliminary tests are made, but no main test. DOTG is considered as not highly flammable under our experimentals conditions.
As a consequence, DOTG will not be classified as flammable.
