Reference
Endpoint:
auto-ignition temperature (gases)
Type of information:
experimental study
Adequacy of study:
key study
Study period:
not specified
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
other: GLP status not known, information from a published handbook, acceptable with restrictions
Justification for type of information:
N/A
Principles of method if other than guideline:
The use of secondary sources of data is acceptable when they are based on a critical evaluation of peer-reviewed data and a consequent selection of a reliable and representative value for the property under investigation. The introduction to the CRC Handbook of Chemistry and Physics states that data for physical constants have been taken from many sources, including both compilations and the primary literature. Where conflicts were found, the value deemed most reliable was chosen. Therefore, although the method used is not known, the values presented here are acceptable as they are from a reliable secondary source of phys chem. data.

Conclusions:
The autoflammability temperature of ethylene is 450°C.
Executive summary:

The autoflammability temperature of ethylene is 450°C. No information on the methods used is available. However, this information is taken from a reliable peer reviewed handbook and so can be considered reliable and suitable for use as the key study for this endpoint.

Description of key information

The auto-flammability temperature of ethylene is 450°C

Key value for chemical safety assessment

Autoflammability / Self-ignition temperature at 101 325 Pa:
450 °C

Additional information

The auto-flammability temperature of ethylene is 450°C (CRC Handbook, Lide 2008). No information on the methods used is available. However, this information is taken from a reliable peer reviewed handbook and so can be considered reliable and suitable for use as the key study for this endpoint. The supporting study, Merck Handbook (O'Neil 2006) is also a peer reviewed handbook and reports a value of 1009 ˚F (543 ˚C) and supports the value reported in the key study.
