Link to relevant study record(s)
- Endpoint:
- relative self-ignition temperature (solids)
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 2002-05-20 - 2002-06-21 (experimental phase)
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:

- Guideline:
- EU Method A.16 (Relative Self-Ignition Temperature for Solids)
- Version / remarks:
- EEC Directive 92/69 EEC, Part A, Methods for the determination of physico-chemical properties, A.16: "Relative self-ignition temperature for solids", EEC Publication No, L383
- Deviations:
- no
- GLP compliance:
- yes (incl. QA statement)
- Specific details on test material used for the study:
- - Storage condition of test material: at room temperature (at about 20 °C)
- Key result
- Remarks on result:
- no self-ignition observed up to the melting point
- Conclusions:
- 1.3-DIMETHYL-4-AMINOURACIL is not auto-flammable, according to the criteria as described in the guideline.
- Executive summary:
The determination of the relative self-ignition temperature of the test item was performed according to the EEC Directive 92/69, Part A, Methods for the determination of physico-chemical properties, A.16 "Relative self-ignition temperature for solids", EEC Publication No. L383, December 1992.
Using a linear increase in temperature of about 0.5 °C/min, 1,3-DIMETHYL-4-AMINOURACIL showed no relevant exothermic reaction. 1,3-DIMETHYL-4-AMINOURACIL (CD 19-0456) has a melting point at about 300 °C. As the above mentioned guideline only applies to solids, the temperature range between 300 °C and 400 °C is not relevant for the present test item. At the end of the measurement 1.3-DIMETHYL-4-AMINOURACIL was run out of the sample cube due to melting and was coloured black.
In conclusion, 1.3-DIMETHYL-4-AMINOURACIL is not auto-flammable.
