- Endpoint:
- relative self-ignition temperature (solids)
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 28 September 2010 to 25 November 2010
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- other: GLP Compliant, guideline study, available as unpublished report, acceptable without restrictions
- Qualifier:
- according to guideline
- Guideline:
- other: N.4 (Modified method) Self Heating Substances test
- Deviations:
- yes
- Remarks:
- the test item was only available in very limited amounts, therefore, in order to obtain as much information as possible on the self-heating properties of the test item a modified procedure was employed
- GLP compliance:
- yes (incl. QA statement)
- Key result
- Relative self-ignition temperature:
- 195 °C
- Remarks on result:
- other: No self-heating when at 140 °C for 24 hrs, but self-heating at 195 °C on increase in oven temperature was increased from 140 to 400 °C.
- Conclusions:
- Palladium (II) acetate showed no self-heating when at 140 °C for 24 hrs, but self-heating at 195 °C on increase in oven temperature was increased from 140 to 400 °C.
- Executive summary:
This is a GLP compliant, guideline study which is considered suitable for use as the key study for this endpoint. Palladium (II) acetate showed no self-heating when at 140 °C for 24 hrs, but self-heating at 195 °C on increase in oven temperature was increased from 140 to 400 °C.

Additional information
O’Connor and Woolley (2011) is a GLP compliant study following a modified N4 method, which is considered suitable for use as the key study for this endpoint. Palladium (II) acetate showed no self-heating when at 140 °C for 24 hrs, but self-heating at 195 °C on increase in oven temperature was increased from 140 to 400 °C.
Vill (2000) is a guideline study considered suitable for use as the key study for this endpoint. Palladium (II) acetate reacts exothermically from 174.5 °C and at an oven temperature of about 180 °C a peak temperature of about 325 °C was measured.
