Test procedure:
ignition time on contact with air
Remarks:
Ignition on contact with air refers to either Pyrophoric solids or Pyrophoric liquids depending on physical state (migrated information).
Remarks on result:
no ignition on contact with air (not further specified)
Remarks:
corresponding to 'no' in migrated source record.

Remarks on result:
no ignition on contact with air (not further specified)
Remarks:
corresponding to 'no' in migrated source record.

No burning times available because the primary screening tests is enough to conclude that the substance is non flammable.

Conclusions:
non flammable
Executive summary:

Preliminary screening test : The substance does not ignite and propagate combustion either by burning with flame or smouldering along 200 mm of the powder train within the 4 minutes (test period), then the substance should not be considered as flammable and no further testing is required (no Burning rate test).

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
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

Description of key information

Flammability (solids)

Cobalt(II) 4-oxopent-2-en-2-olate has not to be classified as flammable solid according to GHS and CLP

Testing of flammability does not appear scientifically necessary according to Regulation (EC) No 1907/2006, Annex XI, Section 1

- Testing for flammability in contact with water (A.12) is not considered to be required, because cobalt(II) 4-oxopent-2-en-2-olate does not contain groups that might lead to a reaction with water or damp air, leading to the development of dangerous amounts of gas or gases which may be highly flammable.

- Testing of pyrophoric properties of solids and liquids (A.13) is not considered to be required, since cobalt(II) 4-oxopent-2-en-2-olate is stable at ambient temperature. It does not contain any chemical group that might lead to spontaneous ignition a short time after coming in contact with air at room temperature (approx. 20 °C).

Key value for chemical safety assessment

Flammability:
non flammable

Additional information

Flammability (solids)

Preliminary screening test:

The substance does not igniteand propagate combustion either by burning with flame or smouldering along 200 mm of the powder train within the 4 minutes (test period), then the substance should not be considered as flammable and no further testing is required (no burning rate test).

Pyrophoric properties

Testing for pyrophoric properties of solids is not considered to be required, since this substance is stable at ambient temperature. This substance also does not contain any chemical groups that might lead to spontaneous ignition a short time after coming in contact with air at room temperature (circa 20 °C) . Furthermore, long-term industrial experience in handling shows that the substance does not ignite in contact with air (in accordance with Regulation (EC) No 1907/2006, Annex XI, Section 1).

Flammability in contact with water

Testing of flammability in contact with water is not considered to be required, because the substance does not contain groups that might lead to a reaction with water or damp air, leading to the development of dangerous amounts of gas or gases which may be highly flammable. Furthermore, long-term industrial experience in practical handling of the substance shows that it does not react with water, and recent experimental testing for water solubility has also not reported any formation of gases (in accordance with Regulation (EC) No 1907/2006, Annex XI, Section 1.2).

Justification for classification or non-classification

Cobalt(II) 4-oxopent-2-en-2-olate does not need to be classified according to CLP Regulation (EC) No 1272/2008 since it is not highly flammable.
