Reference
Endpoint:
auto-ignition temperature (liquids)
Type of information:
experimental study
Adequacy of study:
key study
Study period:
2010-09-20 to 2010-09-22
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
guideline study without detailed documentation
Remarks:
Limited information on test substance
Reason / purpose for cross-reference:
reference to same study
Qualifier:
according to guideline
Guideline:
other: DIN EN 14522 (Method 8)
Deviations:
yes
Remarks:
Lacking detail and information on test substance.
GLP compliance:
no
Specific details on test material used for the study:
- Name as cited in study report: Polyetheramine D 230
- Color: colorless
- Test substance receipt: 2010-09-16
- Analytical Purity: 100%
Key result
Auto-ignition temperature:
230 °C
Atm. press.:
1 009 - <= 1 012 mBar
Remarks on result:
other: Ambient temperature 19-22 deg C during testing; at atm. press. of 1009.0 - <=1012.0 mBar

Additional Remarks on Results :

- Lowest temperature value is reduced by the absolute deviation calculated using the reproducibility value (1.5% rel.).

- Electrical equipment which may be in contact with explosive mixtures of the test substance and air, has to be of temperature class T3 or higher.

- Results relate only to the substance tested.

- Electrical and non-electrical equipment may be used in areas where there is a danger of explosion only if it has been approved for the relevant temperature class.

- In the interior of large heated containers or reactors, flammable gasses and vapours can be ignited in a range up to 50°C below there AIT measured according to the cited standard. Where there are catalytic effects, the temperature effects can be even greater.

Conclusions:
The autoignition temperature (AIT) of the test substance was found to be 230 °C.

Description of key information

The autoignition temperature (AIT) of the test substance was found to be 230 °C (Ambient temperature 19-22 °C during testing) (BASF, 2010).
