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 October 26, 2009 to November 23, 2009
- 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
- Relative self-ignition temperature:
- < 42 °C
- Remarks on result:
- other:
- Remarks:
- at atm. press. of 1.0 atm
- Conclusions:
- Under the study conditions, the test substance was determined not to have a relative self-ignition temperature below the temperature at which it liquefies (approximately 42⁰C).
- Executive summary:
A study was performed to determine the self-ignition temperature of the test substance according to EU Method A.16, in compliance with GLP. An aliquot of the test substance was suspended in a stainless steel mesh cube (approximately 20 x 20 x 20 mm) in an oven. The temperature/time curve relating to conditions in the centre of the sample was recorded while oven temperature was programmed to increase from ambient to 400⁰C at a rate of 0.5⁰C/minute. The observations indicated that, at some point during the heating cycle, the test substance had liquefied allowing it to escape so sample temperature was not recorded (oven temperature was recorded by respective thermocouple). The above procedure was repeated taking into account the liquefaction of the test substance at approximately 42⁰C (melting/freezing temperature determination). Oven temperature was programmed to increase from ambient to 100⁰C. Under the study conditions, the test substance was determined not to have a relative self-ignition temperature below the temperature at which it liquefies (approximately 42⁰C) (Atwal, 2009).
- Endpoint:
- auto-ignition temperature (liquids)
- Data waiving:
- study scientifically not necessary / other information available
- Justification for data waiving:
- the study does not need to be conducted because the substance is a liquid non flammable in air, e.g. no flash point up to 200°C
Referenceopen allclose all
After the test, the cube was empty and a light brown dried solid residue was observed predominately on the floor of the oven with some on the base of the cube support, indicating the test substance had liquefied and escaped from the cube. As a thermocouple was placed at the center of the sample to record the sample temperature, it could not be recorded. Therefore, the test was repeated and the oven temperature was programmed to increase from ambient to 100⁰C.
Description of key information
Solid form: the self-ignition temperature was determined according to EU Method A.16.
Key value for chemical safety assessment
Additional information
Solid form: the test substance was determined not to have a relative self-ignition temperature below the temperature at which it liquefies (approximately 42⁰C)
Brine: The study does not need to conducted because the substance is a liquid non-flammable in air, e.g. no flash point up to 200°C
