Link to relevant study record(s)
- Endpoint:
- relative self-ignition temperature (solids)
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.16 (Relative Self-Ignition Temperature for Solids)
- Relative self-ignition temperature:
- > 400 °C
- Remarks on result:
- other:
- Remarks:
- at atm. press. of 1013.25 hPa
- Conclusions:
- The substance does not ignite when being heated up to 400 °C.
- Endpoint:
- relative self-ignition temperature (solids)
- Type of information:
- read-across from supporting substance (structural analogue or surrogate)
- Adequacy of study:
- key study
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- guideline study
- Justification for type of information:
- Only the edetic acid moiety of the test item can ignite. Thus it is justified to evaluate the flammability of K3EDTA by a read-across approach to Na2EDTA. The exchange of sodium by potassium cations will not effect the flammability. The exchange of one proton by a potassium cation might lower the flammibility. Thus by this approach the auto flammability will not be underestimated.
- Reason / purpose for cross-reference:
- read-across source
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.16 (Relative Self-Ignition Temperature for Solids)
- Relative self-ignition temperature:
- > 400 °C
- Remarks on result:
- other:
- Remarks:
- at atm. press. of 1013.25 hPa
- Conclusions:
- The substance does not ignite when being heated up to 400 °C.

Description of key information
auto flammability K3EDTA: >400°C at 1013.3 hPa
Key value for chemical safety assessment
Additional information
Based on a read-across from the related substance disodiumdihydrogenethylenediaminetetraacetate a self-ignition temperature range of >400°C was determined in a reliable study conducted according to an appropriate test protocol and in compliance with GLP.
