- Endpoint:
- relative self-ignition temperature (solids)
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 22 Oct 2018 - 25 Nov 2018
- 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)
- GLP compliance:

- Specific details on test material used for the study:
- Lot No. Purity Manufactured date Expiry Date
72617S >99% excluding water 7/26/2017 2/1/2019 - Key result
- Relative self-ignition temperature:
- >= 400
- Remarks on result:
- no self ignition observed under the test conditions
- Conclusions:
- The test item, Monalazone Disodium has no relative self-ignition temperature at or below 400°C.
- Executive summary:
The determination of relative self-ignition temperature of test item, Monalazone Disodium was carried out inaccordancewith the method, EEC A.16.
There was no ignition temperature detected at or below 400°C. However, an exothermic reaction was observed at about 212°C, 214.3°C and 217°C for R1, R2 and R3 replications, respectively. Further, on inspection of the sample basket at the end of the experiment, it was observed that the sample basket was full ofbrownish black residuewhich indicated the test item to have decomposed during or immediately after melting. Hence, relative self-ignition temperature of the test item,Monalazone Disodiumwas not obtained for none of the three replications. Thus, the test item, Monalazone Disodium has no relative self-ignition temperature at and below 400°C.
