Reference

Endpoint:

flammable solids

Type of information:

experimental study

Adequacy of study:

key study

Study period:

2008

Reliability:

1 (reliable without restriction)

Rationale for reliability incl. deficiencies:

guideline study

Qualifier:

according to guideline

Guideline:

EU Method A.10 (Flammability (Solids))

Version / remarks:

EEC Directive 92/69

GLP compliance:

no

Other quality assurance:

ISO/IEC 17025 (General requirements for the competence of testing and calibration laboratories)

Key result

Test procedure:

other: burning time over 200 mm

Remarks on result:

other: brief ignition and rapid extinction

Preliminary test:

Burning time (200 mm test distance): brief ignition and rapid extinction. Therefore the preliminary screening test is negative.

Because of the result of the preliminary test the test substance is not considered a flammable solid.

Conclusions:

The test substance is not considered to be a flammable solid.

Description of key information

- Not highly flammable upon ignition.

- No pyrophoric properties

- Does not liberate flammable gases on contact with water

Key value for chemical safety assessment

Flammability:

not classified

Additional information

Bulk form:

The flammability was performed according to EEC Directive 92/69,A.10.

- Upon ignition, the test substance was brief ignition and rapid extinction

- Based on chemical structure and experience in handling and use of substance the pyrophoric properties and the flammability in contact with water are not to be expected.

Justification for classification or non-classification

Based on the experimental data and the experience in handling and use of the substance it can be suggested that the substance should not be classified as a flammable material.
