Administrative data
Link to relevant study record(s)
- Endpoint:
- flammable solids
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 2021-03-29 (experimental phase)
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.10 (Flammability (Solids))
- Version / remarks:
- Test method A.10. "Flammability (solids)" as described in the Council Regulation (EC) No 440/2008 of 30 May 2008 laying down test methods pursuant to Regulation (EC) No 1907/2006 of the European Parliament and of the Council on the Registration, Evaluation, Authorization and Restriction of Chemicals (REACH)
- Deviations:
- not specified
- GLP compliance:
- no
- 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
- Remarks:
- only melting observed
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- The test was properly conducted and documented, hence, the results can be considered reliable. Disodium 1,3,4-thiadiazole-2,5-dithiolate has not to be considered as flammable.
- Executive summary:
The flammability (solids) was determined according to the test method A.10. "Flammability (solids)" as described in theCouncil Regulation (EC) No 440/2008 of 30 May 2008 laying down test methods pursuant to Regulation (EC) No 1907/2006 of the European Parliament and of the Council on the Registration, Evaluation, Authorization and Restriction of Chemicals (REACH).
According to the definition in the Council Regulation (EC) No 440/2008 that is pursuant to Regulation (EC) No 1907/2006 the test item Disodium 1,3,4-thiadiazole-2,5-dithiolate has not to be considered as flammable.
Reference
Description of key information
A flammability (solid) study with the test substance was performed according to test method A.10. Based on the results obtained (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, only melting observed), the test substance is not flammable.
Flammability – Emission of flammable gases in contact with water was waived based on experience in production and handling as well as Flammability-pyrophoric solid as the test substance in its distributed form is known to be stable in contact with air for long period and there are no chemical groups present that would imply pyrophoric properties.
Key value for chemical safety assessment
- Flammability:
- not classified
Additional information
Justification for classification or non-classification
Based on results of a flammability (solid) study. The test substance is not flammable, does not spontaneously ignite and does not emit flammable gases.
