Link to relevant study record(s)
- Endpoint:
- relative self-ignition temperature (solids)
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- From February 16, 2007 to April 27, 2007
- 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:
- yes (incl. QA statement)
- Key result
- Relative self-ignition temperature:
- > 403 °C
- Remarks on result:
- other: at atm. press. of ca.1013.0 hPa
- Conclusions:
- Under the study conditions, no self-ignition temperature for the test substance was observed up to the maximum test temperature of 403°C.
- Executive summary:
A study was conducted to determine the self-ignition temperature of test substance, DDAC (99.8% active) according to the EU Method A.16, in compliance with GLP. 8 cm3(2.7 g) of the test substance was placed in an oven under increasing temperature up to 400°C at a rate of 0.5°C/min. Purified active substance (obtained via lyophilation of aqueous solution) was used in the study. Under the study conditions, no self-ignition temperature for the test substance was observed up to the maximum test temperature of 403°C (Moller, 2007).
- Endpoint:
- relative self-ignition temperature (solids)
- Type of information:
- read-across from supporting substance (structural analogue or surrogate)
- Adequacy of study:
- key study
- Study period:
- From February 16, 2007 to April 27, 2007
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- guideline study with acceptable restrictions
- Remarks:
- KL2 due to RA
- Justification for type of information:
- Refer to section 13 of IUCLID for details on the read-across justification. The study with the read across substance is considered sufficient to fulfil the information requirements as further explained in the provided endpoint summary.
- Reason / purpose for cross-reference:
- read-across source
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.16 (Relative Self-Ignition Temperature for Solids)
- GLP compliance:
- yes (incl. QA statement)
- Key result
- Relative self-ignition temperature:
- > 403 °C
- Remarks on result:
- other: at atm. press. of ca.1013.0 hPa
- Conclusions:
- Based on the results of the read across study, no self-ignition temperature for the test substance was considered up to the maximum test temperature of 403°C.
- Executive summary:
A study was conducted to determine the self-ignition temperature of read across substance, DDAC (99.8% active) according to the EU Method A.16, in compliance with GLP. 8 cm3(2.7 g) of the read across substance was placed in an oven under increasing temperature up to 400°C at a rate of 0.5°C/min. Purified active substance (obtained via lyophilation of aqueous solution) was used in the study. Under the study conditions, no self-ignition temperature for the read across substance was observed up to the maximum test temperature of 403°C (Moller, 2007). Based on the results of the read across study, no self-ignition is expected for the test substance up to 403°C.
