Reference 1

Endpoint:

flammable solids

Type of information:

experimental study

Adequacy of study:

key study

Study period:

November 19, 2010

Reliability:

1 (reliable without restriction)

Rationale for reliability incl. deficiencies:

other: Well conducted study, according to Guideline A.10 given in EC Regulation No 440/2008 under Internal management system, certificate of analysis included in the report.

Qualifier:

according to guideline

Guideline:

EU Method A.10 (Flammability (Solids))

Version / remarks:

EC 440/2008

Deviations:

no

GLP compliance:

no

Remarks:

Internal management system

Key result

Test procedure:

burning time (test type not further specified)

Remarks:

or specified in description of method (migrated information)

Remarks on result:

other: No propagation of combustion

In the screening test the gas flame was applied for 2 minutes to one end of the substance train. The substance locally ignited immediately, but no propagation of combustion occurred. This means that the substance shall not be classified as a flammable solid.

Interpretation of results:

non flammable

Remarks:

Migrated information

Conclusions:

The flammability test with Titanocene dichloride (TDC) was carried out to determine whether this substance shall be classified as a flammable solid according to EC Regulation No 1272/2008 (CLP). Based on the test result Titanocene dichloride shall not be classified as a flammable solid.

Executive summary:

The flammability test with Titanocene dichloride (TDC) was carried out to determine whether this substance shall be classified as a flammable solid according to EC Regulation No 1272/2008 (CLP). Based on the test result Titanocene dichloride shall not be classified as a flammable solid.

Reference 2

Endpoint:

pyrophoric solids

Data waiving:

study scientifically not necessary / other information available

Justification for data waiving:

the study does not need to be conducted because the substance is known to be stable in contact with air at room temperature for prolonged periods of time (days) and hence, the classification procedure does not need to be applied

Reference 3

Endpoint:

substances / mixtures which in contact with water emit flammable gases

Data waiving:

study scientifically not necessary / other information available

Justification for data waiving:

the study does not need to be conducted because the experience in production or handling shows that the substance does not react with water, e.g. the substance is manufactured with water or washed with water

Reference 4

Endpoint:

self-heating substances / mixtures

Type of information:

experimental study

Adequacy of study:

key study

Study period:

November 17-22, 2010

Reliability:

1 (reliable without restriction)

Rationale for reliability incl. deficiencies:

other: Well conducted study, according to Guideline N.4 under Internal management system, certificate of analysis included in the report.

Qualifier:

according to guideline

Guideline:

UN Manual of Tests and Criteria: Test N.4 (Test method for self-heating substances)

Deviations:

no

GLP compliance:

no

Remarks:

Internal management system

Key result

Test procedure:

25 mm sample cube at 140°C

Max. temp. reached:

140

Induction time (h):

24

Result:

negative outcome (no effect observed)

Key result

Test procedure:

100 mm sample cube at 140°C

Max. temp. reached:

140

Induction time (h):

90

Result:

negative outcome (no effect observed)

Calibration date: November 22, 2010

The deviation of the thermocouples was within the estimated accuracy of the test method, which is +/- 1.5 oC.

Interpretation of results:

not classified based on GHS criteria

Conclusions:

The UN self-heating test with Titanocene dichloride (TDC) was carried out to determine
whether this substance shall be classified as a self-heating substance or mixture according
to EC Regulation No 1272/2008 (CLP) [1]. The study was performed in accordance with test
method N.4 given in the UN Manual on Tests and Criteria [2]. Two tests were performed i.e.
the test in the 25 mm sample cube at 140°C and the test in the 100 mm sample cube at
140°C.
Based on the test results Titanocene dichloride (TDC) shall not be classified as a selfheating
substance.

Executive summary:

Based on the test results Titanocene dichloride (TDC) shall not be classified as a selfheating

substance.

Description of key information

Titanocene dichloride shall not be classified as a flammable solid.  The substance is not pyrophoric, does not emit flammable gases on contact with water and is not self-heating

Key value for chemical safety assessment

Flammability:

non flammable

Additional information

Based on the test result of the flammability test (Guideline A.10) and self-heating test (test method N.4) with Titanocene dichloride (TDC) to determine whether this substance shall be classified as a flammable solid or self-heating solid according to EC Regulation No 1272/2008 (CLP).
