Endpoint:
flammable solids
Type of information:
experimental study
Adequacy of study:
key study
Study period:
28 September 2010 to 13 December 2010
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
other: GLP Compliant, guideline study, available as unpublished report, acceptable without restrictions
Qualifier:
equivalent or similar to guideline
Guideline:
UN Manual of Tests and Criteria: Test N.1 (Test method for readily combustible solids)
Deviations:
no
GLP compliance:
yes (incl. QA statement)
Test procedure:
burning rate test: preliminary screening test
Remarks on result:
other: Pile ignited and burned with an orange flame, which propagated along the 200mm length in 54 seconds. Residue was a dark grey ash.
Test procedure:
burning rate test over 100 mm length
Remarks on result:
other: Pile ignited and burnt with a stable, yellow-orange flame, which propagated along the 100mm length, after an initial burning distance of 80mm in 34 seconds. Residue was dark grey ash. Wetted zone failed to hold up the flame propagation.

Preliminary Screening Test: Pile ignited and burned with an orange flame, which propagated along the 200mm length in 54 seconds. Residue was a dark grey ash.

Main Test: Pile ignited and burnt with a stable, yellow-orange flame, which propagated along the 100mm length, after an initial burning distance of 80mm in 34 seconds. Residue was dark grey ash. Wetted zone failed to hold up the flame propagation.

Conclusions:
Palladium (II) di(4-oxopent-2-en-2-oate) has been classified as Category 1 of the Flammable Solids Criteria of Regulation (EC) No 1272/2008 of 16 December 2008, on Classification, Labelling and Packaging of Substances and Mixtures
Executive summary:

This is a GLP compliant, guideline study considered suitable for use as the key study for this endpoint. Palladium (II) di(4-oxopent-2-en-2-oate) has been classified as Category 1 of the Flammable Solids Criteria of Regulation (EC) No 1272/2008 of 16 December 2008, on Classification, Labelling and Packaging of Substances and Mixtures.

Description of key information

In the main flammability study, the pile ignited and burnt with a stable, yellow-orange flame, which propagated along the 100mm length, after an initial burning distance of 80mm in 34 seconds. Residue was dark grey ash. wetted zone failed to hold up the flame propagation. 
Palladium (II) di(4-oxopent-2-en-2-oate) has been classified as Category 1 of the Flammable Solids Criteria of Regulation (EC) No 1272/2008 of 16 December 2008, on Classification, Labelling and Packaging of Substances and Mixtures.

Key value for chemical safety assessment

Flammability:
highly flammable

Additional information

Walker and White (2011) is a GLP compliant, guideline study considered suitable for use as the key study for this endpoint. In the main flammability study, the pile ignited and burnt with a stable, yellow-orange flame, which propagated along the 100mm length, after an initial burning distance of 80mm in 34 seconds. Residue was dark grey ash. Wetted zone failed to hold up the flame propagation. Palladium (II) di(4-oxopent-2-en-2-oate) has been classified as Category 1 of the Flammable Solids Criteria of Regulation (EC) No 1272/2008 of 16 December 2008, on Classification, Labelling and Packaging of Substances and Mixtures

Meinerling (2006) is a GLP compliant, guideline study and is considered reliable and suitable for use as a supporting study for this endpoint. Palladium (II) di(4-oxopent-2-en-2-oate) is considered to be highly flammable.

Justification for classification or non-classification

Based on GLP-compliant, guideline studies palladium (II) di(4 -oxopent-2 -en-2 -oate) has been classified as a Category 1 flammable solid. Palladium (II) di(4-oxopent-2-en-2-oate) is also classified as a self-heating solid, category 1.
