- Endpoint:
- auto-ignition temperature (liquids)
- Type of information:
- experimental study
- Adequacy of study:
- weight of evidence
- 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))
- Deviations:
- no
- GLP compliance:
- yes
- Key result
- Auto-ignition temperature:
- 435 °C
- Remarks on result:
- other: see Remarks
- Remarks:
- 5 %
- Conclusions:
- The auto-ignition temperatures of the 5% PAA products was 435 °C.
- Executive summary:
The auto-ignition temperatures of the 5% PAA products was 435°C. Solutions with PAA concentrations not exceeding 15% PAA are regarded as not flammable under conditions where the liquid is open to the atmosphere. Solutions with more than 15% PAA exhibit both open and closed-cup flash points and vapours can be flammable. No derivation from the guideline.

The measured lowest ignition temperatures of the main test are > 300 °C and do not differ by more than 20 °C, thus the test is satisfactory. The individual results are 455, 436, 438 °C respectively. The auto-ignition temperature is defined as the lowest temperature of all single results of the main test, but rounded down to multiples of 5 °C.
Auto-ignition temperature: 435 °C
The measured lowest ignition temperatures of the main test are < 300 °C and do not differ by more than 10 °C, thus the test is satisfactory. The individual results are 280, 280, 280 °C respectively. The auto-ignition temperature is defined as the lowest temperature of all single results of the main test, but rounded down to multiples of 5 °C.
Auto-ignition temperature: 280 °C
Description of key information
Auto-ignition temperature: 435 °C (5%), 280 °C (15%) (EU A.15)
Key value for chemical safety assessment
Additional information
The auto-ignition temperatures of the 5% and 15% peracetic acid products were 435 °C and 280 °C, respectively (Mekelburger, 2007). Solutions with concentrations not exceeding 15 % peracetic acid are regarded as not flammable under conditions where the liquid is open to the atmosphere. Solutions with more than 15% peracetic acid exhibit both open and closed-cup flash points and vapours can be flammable.
