Auto flammability
Administrative data
Link to relevant study record(s)
- Endpoint:
- relative self-ignition temperature (solids)
- Type of information:
- read-across from supporting substance (structural analogue or surrogate)
- Adequacy of study:
- key study
- Justification for type of information:
- ANALOGUE APPROACH JUSTIFICATION
Read across from sodium cyanate was performed instead. No differences in auto ignition temperature are expected. The ions K+ and Na+ are not expected to contribute to auto ignition properties of the cyanates. The test item sodium cyanate is considered as not auto-flammable. Thus, also potassium cyanate is considered as not auto-flammable. - Reason / purpose for cross-reference:
- read-across source
- Key result
- Remarks on result:
- no self ignition observed under the test conditions
- Endpoint:
- relative self-ignition temperature (solids)
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 2008-12-19 to 2009-08-27
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.16 (Relative Self-Ignition Temperature for Solids)
- Deviations:
- no
- GLP compliance:
- yes (incl. QA statement)
- Key result
- Remarks on result:
- no self ignition observed under the test conditions
- Conclusions:
- The test item sodium cyanate is considered as not auto-flammable
- Executive summary:
The test was performed with an analoguous material, sodium cyanate. The auto-flammability behaviour was determined by placing the test item into a stainless steel cube and heating the environment (laboratory oven with automatic temperature re-cording) from room temperature to 400 °C. No increase in the temperature of the sample in comparison to that of the oven could be detected, also no signs of ignition could be observed.The test item sodium cyanate is considered as not auto-flammable. It can be concluded that potassium cyanate is likewise not auto-flammable.

Description of key information
No study is available for potassium cyanate. Read-across from sodium cyanate was performed instead. No differences in auto ignition temperature are expected. The ions K+ and Na+ are not expected to contribute to auto ignition properties of the cyanates. The test item sodium cyanate is considered as not auto-flammable. Thus, also potassium cyanate is considered as not auto-flammable.

Additional information
The auto-flammability behaviour was determined by placing the test item into a stainless steel cube and heating the environment (laboratory oven with automatic temperature recording) from room temperature to 400 °C. No increase in the temperature of the sample in comparison to that of the oven could be detected, also no signs of ignition could be observed. Therefore, the test item sodium cyanate is considered as not auto-flammable.
