Endpoint:
flammable solids
Type of information:
experimental study
Adequacy of study:
key study
Study period:
From 28 June 2005 to 4 October 2005
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
guideline study
Reason / purpose for cross-reference:
reference to same study
Qualifier:
according to guideline
Guideline:
EU Method A.10 (Flammability (Solids))
Deviations:
yes
Remarks:
See below for details.
Principles of method if other than guideline:
Deviation: the ignition source is a platinum wire heated by electrical power (current 30A, about 1000 °C) instead a direct flame as proposed in the guideline A.10. As indicated by the study director, this modification does not have any effect on the conclusion of the test.
GLP compliance:
yes (incl. QA statement)
Key result
Test procedure:
burning rate test over 100 mm length
Remarks on result:
other: The test item did not ignite.
Remarks:
No further testing was required.

The test item didn’t burn. No further testing was required.

Interpretation of results:
GHS criteria not met
Conclusions:
Iron oxide isotearate is not “highly flammable” under the conditions of the test.
Executive summary:

The flammability of iron oxide isostearate was assessed according to EU Guideline A.10 and GLP.

The test item didn’t burn. No further testing was required.

Iron oxide isostearate is not highly flammable.

no
Key result
Test procedure:
ignition time on contact with air
Remarks on result:
no ignition within 5 minutes
Remarks:
Same result obtained for the 6 repetitions.
Interpretation of results:
GHS criteria not met
Conclusions:
For iron oxide isostearate the test was negative. No inflammation was observed during or after the fall.
Executive summary:

 The pyrophoric properties of iron oxide isostearate was tested in accordance to EU Method A.13.

The test was negative. No inflammation was observed during or after the fall.

Description of key information

Iron oxide isostearate is not flammable, not pyrophoric and not flammable in contact with water under the conditions of the tests.

Key value for chemical safety assessment

Flammability:
not classified

Additional information

GLP experimental studies, according to EU Methods A.10, A.12 and A.13 and scored as Klimisch 1, are available for flammability, flammability in contact with water and pyrophoricity, respectively. They were selected as key studies; concluding that iron oxide isostearate is not flammable, not pyrophoric, and not flammable in contact with water.

Justification for classification or non-classification

Based on the above data, iron oxide isostearate does not require a classification regarding its flammable properties under CLP.
