Administrative data

Endpoint:
auto-flammability
Type of information:
experimental study
Adequacy of study:
key study
Study period:
2002
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
other: The result was obtained from a collection of reliable data which has been subject to peer-review and in which the original data sources are traceable.

Test material

Constituent 1
Reference substance name:
propylene oxide
IUPAC Name:
propylene oxide
Constituent 2
Reference substance name:
Methyloxirane
EC Number:
200-879-2
EC Name:
Methyloxirane
Cas Number:
75-56-9
IUPAC Name:
2-methyloxirane
Details on test material:
Test material was racemate from both R(+) and S(-) propylene oxide. This endpoint is not measured / determined with enantio-selective sensors.
Therefore the S(-) value is identical to the racemate endpoint.

Results and discussion

Auto-ignition temperature (liquids / gases)
Auto-ignition temperature:
420 °C
Remarks on result:
other: The lower value of the two reliable study endpoints was selected as a worst case.
Relative self-ignition temperature (solids)
Relative self-ignition temperature:
420 °C
Remarks on result:
other: The lower value of the two reliable study endpoints was selected as a worst case.

Any other information on results incl. tables

Autoignition temperatures of 420°C (Elm, cited in Ullmans Encyklopädie der technischen Chemie, 1980) and 430°C (BASF AG, 1993) were reported. Both were conducted to an accepted Annex V test method (DIN 51794) although the actual test data were not provided. A value of 465°C (quoted in the NFPA handbook, 1994) could not be assigned.

Applicant's summary and conclusion

Conclusions:
An auto ignition temperature of 420°C was determined in a reliable study conducted according to an appropriate test protocol. No further details are
available.
