Administrative data
Link to relevant study record(s)
- Endpoint:
- auto-ignition temperature (liquids)
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- The study was conducted between 09 April 2006 and 21 April 2006
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.15 (Auto-Ignition Temperature (Liquids and Gases))
- GLP compliance:
- yes (incl. QA statement)
- Specific details on test material used for the study:
- Sponsor's identification: BHES-100X
Description: white solid block
Batch number: 5K0718-CC
Date received: 21 January 2006
Storage conditions: room temperature, over silica gel, in the dark - Key result
- Auto-ignition temperature:
- 394 °C
- Atm. press.:
- >= 101.28 - <= 102.2 kPa
- Conclusions:
- The test material has been determined to have an auto-ignition temperature of 394 ± 5°C.
- Executive summary:
The auto-ignition temperature was determined by heating aliquots of the test material in a flask and observing for any ignition. Testing was conducted using Method Al5 of Commission Directive 92/69/EEC (which constitutes Annex V of Council Directive 67 /548/EEC). The test material has been determined to have an auto-ignition temperature of 394 ± 5°C.
