- Qualifier:
- according to guideline
- Guideline:
- EU Method A.15 (Auto-Ignition Temperature (Liquids and Gases))
- Qualifier:
- according to guideline
- Guideline:
- DIN EN 14522, Method S (Determination of the auto ignition temperature of gases and vapours)
- GLP compliance:
- no
- Other quality assurance:
- other: ISO 9001:2008
- Key result
- Auto-ignition temperature:
- 207 °C
- Atm. press.:
- ca. 972 - ca. 977 hPa
- Conclusions:
- An auto flammability value of 207°C at 972 to 977 hPa was determined for the substance in accordance with a relevant test method and in compliance with a known quality system (ISO 9001:2008). The result is considered to be reliable.
