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other: GLP Compliant, guideline study, available as unpublished report, acceptable without restrictions
Reference:
Composition 1
Qualifier:
according to
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. certificate)
Test material information:
Composition 1
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.

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.

Description of key information

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. 

Key value for chemical safety assessment

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.
