29 December 2016 to 30 December 2016

Reliability:

1 (reliable without restriction)

Rationale for reliability incl. deficiencies:

guideline study

Reason / purpose for cross-reference:

reference to same study

Qualifier:

according to guideline

Guideline:

UN Manual of Tests and Criteria: Test N.1 (Test method for readily combustible solids)

Version / remarks:

2015

Deviations:

no

GLP compliance:

Specific details on test material used for the study:

SOURCE OF TEST MATERIAL
- Batch No.of test material: YBF1002/16
- Expiration date of the lot/batch: 17 October 2018

STABILITY AND STORAGE CONDITIONS OF TEST MATERIAL
- Storage condition of test material: Room temperature over silica gel, in the dark

Key result

Test procedure:

burning rate test: preliminary screening test

Burning time:

0 s

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

The test material melted but failed to ignite during the 2 minutes that the Bunsen flame was applied. The result of the preliminary screening test obviated the need to perform the definitive test.

Interpretation of results:

other: Not highly flammable in accordance with EU criteria

Conclusions:

Under the conditions of this study, the test material is not classified as a flammable solid.

Executive summary:

The flammability of the test material was investigated in accordance with the standardised guideline UN Test N.1 under GLP conditions.

A preliminary screening test was performed and no propagation of combustion of the test material along the 200 mm length of the pile within 2 minutes was observed. The definitive burning rate test was not required.

Under the conditions of this study, the test material is not classified as a flammable solid.

Description of key information

Under the conditions of this study, the test material is not classified as a flammable solid.

Key value for chemical safety assessment

Flammability:

not classified

Additional information

Flammability

The flammability of the test material was investigated in accordance with the standardised guideline UN Test N.1 under GLP conditions. The study was awarded a reliability score of 1 in accordance with the criteria set forth by Klimisch et al. (1997).

A preliminary screening test was performed and no propagation of combustion of the test material along the 200 mm length of the pile within 2 minutes was observed. The definitive burning rate test was not required.

Under the conditions of this study, the test material is not classified as a flammable solid.

Pyrophoricity

In accordance with point 1 of Annex XI, it is considered justified to omit the testing for pyrophoric properties. Testing does not appear scientifically necessary as experience in use and experience of handling the substance indicates that it does not possess pyrophoric properties.

Flammability in contact with water

In accordance with point 1 of Annex XI, it is considered justified to omit the testing for substances or mixtures which in contact with water emit flammable gases. Testing does not appear scientifically necessary as experience in use and experience of handling the substance indicates that it does not emit flammable gases in contact with water.

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.
