Reference

Reference 1

Endpoint:

flammable solids

Data waiving:

study technically not feasible

Justification for data waiving:

the study does not need to be conducted because the substance is a liquid

Reference 2

Endpoint:

substances / mixtures which in contact with water emit flammable gases

Type of information:

experimental study

Adequacy of study:

key study

Study period:

28 September 2001

Reliability:

1 (reliable without restriction)

Rationale for reliability incl. deficiencies:

guideline study

Qualifier:

according to guideline

Guideline:

EU Method A.12 (Flammability (Contact with Water))

GLP compliance:

yes

Substances which, in contact with water or damp air, evolve highly flammable gases in dangerous quantities at a minimum rate of 1 litre/kg per hour are highly flammable. Composition: 27% solution of methyl isopropyl ketone peroxide in dimethylphthalate. From the composition of it can be concluded that the test substance does not contain groups that might lead to evolution of highly flammable gases in dangerous quantities. Furthermore, no metals, transition metals, boron or silicon are present. A few drops of water were added to the test substance. No evolution of gas was observed. From this, it can be concluded that the test substance is incapable of developing a dangerous amount of (flammable) gas in contact with air, damp air or water.

Interpretation of results:

not classified based on GHS criteria

Conclusions:

It can be concluded that the test substance is incapable of developing a dangerous amount of (flammable) gas in contact with air, damp air or water.

Executive summary:

Reference 3

Endpoint:

pyrophoric liquids

Type of information:

experimental study

Adequacy of study:

key study

Study period:

15 October 2001

Reliability:

Rationale for reliability incl. deficiencies:

guideline study

Qualifier:

according to guideline

Guideline:

EU Method A.13 (Pyrophoric Properties of Solids and Liquids)

GLP compliance:

yes

Key result

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.

No ignition occured within five minutes, after adding the test substance to celite and no ignition or charing was observed within five minutes after adding the test substance to a filter paper. The temperature in the fume cupboard was measured to be 21 °C. From this it is concluded that it is not pyrophoric, under the conditions of the test.

Interpretation of results:

not classified based on GHS criteria

Conclusions:

In conclusion, the substance is not to be classified "Pyrophoric" according to the criteria in the method A.13 of EEC-Directive 92/69 EEC.

Executive summary:

The determination of the pyrophoric properties was performed inaccordance with EEC-Directive 92/69 EEC, A.13 "Pyrophoric properties of solids and liquids". No ignition occurred within five minutes, after adding the test substance to celite and no ignition or charring was observed within five minutes after adding the test substance to a filter paper.

In conclusion, the substance is not to be classified "Pyrophoric" according to the criteria in the method A.13 of EEC-Directive 92/69 EEC.

Reference 4

Endpoint:

self-heating substances / mixtures

Data waiving:

study technically not feasible

Justification for data waiving:

the study does not need to be conducted for organic peroxides

Description of key information

Not flammable in contact with water, not pyrophoric.

Justification for classification or non-classification

The test substance is not flammable in contact with water and not pyrophoric under the conditions of the test. Therefore classification is not warranted for these points. Based on the flash point, 72 °C, the substance is not classified according to CLP.
