Link to relevant study record(s)
- Endpoint:
- auto-ignition temperature (gases)
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- From 11 November 2016 to 17 March 2017
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- other: ASTM Method E-659
- Deviations:
- yes
- Remarks:
- A horizontally oriented 2.25 steel vessel was used instead of an open 500 ml glass flask. Due to the test item properties, it is not possible to perform the study without this deviation.
- GLP compliance:
- yes
- Specific details on test material used for the study:
- - Analytical purity: 99.7%w/w
- Impurities (identity and concentrations): organic impurities 0.3% w/w
- Purity test date: 18 January 2017
- Lot/batch No.: 1507 - Key result
- Remarks on result:
- not determinable
- Conclusions:
- No auto ignition of the test item was observed up to 500°C.
- Executive summary:
The auto ignition of the test item was determined according to ASTM Method E-659 and under GLP.
A deviation from the guideline was observed during the study. A horizontally oriented 2.25 steel vessel was used instead of an open 500 ml glass flask. Due to the test item properties, it is not possible to perform the study without this deviation.
The determination of the test item auto ignition temperature was conducted in a custom designed and fabricated by the testing laboratory.
After heating of the apparatus at the required test temperature, the test item was introduced into the test vessel (previously emptied).
The temperature and the pressure of the test vessel were followed by a thermocouple and a pressure transducer. Any rapid rise in temperature and pressure would denote an ignition event.
No auto ignition of the test item was observed up to 500°C.
Reference
Four assays (concentration between 1 and 25% of test item) have been performed at the maximum temperature of the reactor (500°C). No evidence of auto ignition was seen.
Description of key information
The auto ignition temperature of the test item was determined with a key study of reliability 1.
The study was performed according to ASTM Method E-659 and under GLP.
A deviation from the guideline was observed during the study. A horizontally oriented 2.25 steel vessel was used instead of an open 500 ml glass flask. Due to the test item properties, it is not possible to perform the study without this deviation.
Key value for chemical safety assessment
Additional information
Based on the results of the key study, no auto ignition temperature can be specified as key value for chemical safety assessment. Indeed, no evidence of auto ignition has been observed in this study.
