long chain alkyl thio carbamide metal complex

Flammability

Link to relevant study record(s)

Reference

Reference 1

Endpoint:

flammable solids

Remarks:

described as very viscous liquid, tested as solid

Type of information:

experimental study

Adequacy of study:

key study

Study period:

18 October 1999 -03 November 1999

Reliability:

2 (reliable with restrictions)

Rationale for reliability incl. deficiencies:

guideline study with acceptable restrictions

Qualifier:

according to guideline

Guideline:

EU Method A.10 (Flammability (Solids))

Deviations:

yes

Remarks:

the 'rope' of test substance used had a cross-section of 1 cm, whereas the guideline recommends 2 cm

GLP compliance:

yes

Key result

Test procedure:

burning rate test: preliminary screening test

Remarks:

Under the terms of the test method, the full burning rate test was not required because the test substance did not ignite or propagate along the test pile.

Remarks on result:

substance does not ignite and propagate combustion either by burning with flame or smouldering along 200 mm of the powder train within the 2 minutes test period

Interpretation of results:

GHS criteria not met

Conclusions:

In a GLP study, EC# 434-650-5 was tested for flammability according to the EU Method A.10. It failed to ignite under the conditions of the test, and so is considered not highly flammable.

Executive summary:

In a GLP study, the flammability of EC# 434-650-5 was determined using the EU Method A.10 for testing the flammability of solids. The test substance was spread on a non-combustible, non-porous, low-conducting board in the form of a "rope", 250 mm in length and with a cross section of approximately 1 cm2. A flame with a minimum diameter of 5 mm was applied to one end for 2 minutes.

The test substance melted and gave off some smoke and vapour, but failed to ignite and there was no propagation of the flame. The substance is, therefore, considered to be not highly flammable.

Type of information:

read-across from supporting substance (structural analogue or surrogate)

Adequacy of study:

key study

Reason / purpose for cross-reference:

Key result

Test procedure:

burning rate test: preliminary screening test

Remarks:

Under the terms of the test method, the full burning rate test was not required because the test substance did not ignite or propagate along the test pile.

Remarks on result:

The test substance melted and gave off some smoke and vapour, but failed to ignite and there was no propagation of the flame. The substance is, therefore, considered to be not highly flammable.

Executive summary:

In view of the structural and chemical similarities, it is considered that the results of this study can be used for read-across to EC# 457-320-2.

Description of key information

In a GLP study, EC# 434-650-5 was tested for flammability according to the EU Method A.10. It failed to ignite under the conditions of the test, and so is considered not highly flammable. This result can be read-across to EC#457-320-2.

Key value for chemical safety assessment

Flammability:

non flammable

Additional information

In a GLP study, EC# 434-650-5 was tested for flammability according to the EU Method A.10. It failed to ignite under the conditions of the test, and so is considered not highly flammable. This result can be read-across to EC#457-320-2.
