Flammability

Link to relevant study record(s)

Reference

Endpoint:

pyrophoric liquids

Type of information:

experimental study

Adequacy of study:

key study

Reliability:

1 (reliable without restriction)

Rationale for reliability incl. deficiencies:

other: GLP guideline study

Qualifier:

according to guideline

Guideline:

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

Deviations:

no

GLP compliance:

yes

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.

Remarks on result:

ambiguous

Results:

There were 6 tests conducted using diatomaceous, earth all of them with the following result: The test material initially remained on the surface but gradually soaked in. There were no signs of any reaction and no fumes were observed.

There were 3 tests using filter paper, all with the following results: The test material initially remained on the filter paper before gradually soaking into the paper. There were no signs of any reaction, fumes, charring or ignition of the filter paper.

Interpretation of results:

other: Not classified according to EU criteria.

Conclusions:

The test material has been determined to be non-pyrophoric as it did not spontaneously ignite.

Executive summary:

The pyrophoric properties of the test material have been determined using Method A13 Pyrophoric Properties of Solids and Liquids of Commission Regulation (EC) No 440/2008 of 30 May 2008, in accordance with Council Directive 98/8/EC, Annex II.

The test material was determined to be non-pyrophoric.

Description of key information

Flammability: non-pyrophoric 

Key value for chemical safety assessment

Flammability:

non flammable

Additional information

The flammability was determined in a Method A13 Council Directive study.

There were 6 tests conducted using diatomaceous earth, all of them with the following result: The test material initially remained on the surface but gradually soaked in. There were no signs of any reaction and no fumes were observed.

There were 3 tests using filter paper, all with the following results: The test material initially remained on the filter paper before gradually soaking into the paper. There were no signs of any reaction, fumes, charring or ignition of the filter paper.

The test material was determined to be non-pyrophoric.

In accordance with Section 1 of REACH Annex XI, it is considered justified to omit the testing for substances or mixtures which in contact with water emit flammable gases (section 7.10 of Annex VII). Testing does not appear scientifically necessary as, based upon the chemical structure, water activity is not to be expected; this has been corroborated by the practical handling and use of the chemical over time.

 

In accordance with Section 2 of REACH Annex XI, it is not technically possible to conduct the flammability (solids) test required under section 7.10 of Annex VII. The substance is a liquid and hence testing is not technically feasible. The flash point is the more appropriate measure of flammability for this type of material.

Justification for classification or non-classification

In accordance with the criteria for classification as defined in Annex I, Regulation (EC) No 1272/2008, the substance does not require classification with respect to flammability.
