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

No self-ignition temperature was observed up to the maximum test temperature of 403 °C.

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

No self-ignition temperature was observed up to the maximum test temperature of 403 °C.

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.

Description of key information

The self-ignition temperature of the read across substance, DDAC, was determined according to EU Method A.16 (Moller, 2007).
