Preliminary Test: The test substance melted on contact with the burner flame but did not propagate combustion. The burning time could not be measured.

Interpretation of results:
other: not classified
Endpoint:
flammable solids
Type of information:
experimental study
Adequacy of study:
supporting study
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
other: Guideline study conducted in a laboratory issued with a statement of compliance with GLP. Minimum details provided.
Reason / purpose for cross-reference:
reference to same study
Qualifier:
according to guideline
Guideline:
other: UN RTDG, Manual of Tests and Criteria, ST/SG/AC.10/11/Rev.5, Test N1, Burning rate test
Deviations:
yes
Remarks:
draft along the train of material; pile dimensions oversized; also conducted at 100°C
Qualifier:
according to guideline
Guideline:
other: VDI 2263 Part 8, 2008
Deviations:
not specified
Principles of method if other than guideline:
The full burning rate test was performed.
GLP compliance:
no
Remarks:
Conducted in a laboratory issued with a statement of compliance with GLP
Test procedure:
burning time (test type not further specified)
Remarks:
or specified in description of method (migrated information)
Burning time:
125 s
Remarks on result:
other: for 100 mm at 20 °C, air flow 0.5 m/s

The material exhibited combustion properties in the test. The combustion propagated fully by melting and burning with flame.

Combustion Class 5

The test was repeated at 100 °C, airflow 0.5 m/s; burning time for 100 mm = 50 s.

The material exhibited combustion properties in the test. The combustion propagated fully by melting and burning with flame.

Combustion Class 5

Interpretation of results:
other: not classified
Conclusions:
The deviations from the guideline would likely overestimate the burning rate. The result of not readily combustible is thus considered to be reliable.

Description of key information

Flammability (solids): not readily combustible, EU Method A.10, Jackson 1999
Flammability (solids): not readily combustible, UN Method N.1, Bailey 2010
Flammability (contact with water): no gas evolution; no ignition, EU Method A.12, Jackson 1999
Flammability (contact with air): no spontaneous ignition at ambient temperature, EU Method A.13, Jackson 1999

Key value for chemical safety assessment

Flammability:
not classified

Additional information

A single study conducted according to Regulation (EC) No. 440/2008 guidelines and under GLP is available for each aspect of flammability. The studies are considered to be relevant, reliable (Klimisch 1) and adequate for the purposes of risk assessment, classification and labelling.

A further non-GLP study, conducted according to the UN Recommendations on the Transport of Dangerous Goods, Manual of Tests and Criteria, 5th Ed., Test N1, also indicated that the substance was not readily combustible. However, under the conditions of the test combustion propagated fully, but longer than the cut-off criteria.

Justification for classification or non-classification

The available experimental test data are considered reliable and suitable for classification purposes under Regulation (EC) No. 1272/2008, Annex I, section 2.7, 2.10, 2.12. The substance is not considered to be flammable according to the criteria given in test methods N1, N2, and N5 of the UN Recommendations on the Transport of Dangerous Goods, Manual of Tests and Criteria, Part III. As a result the substance is not considered to be classified for flammability under Regulation (EC) No. 1272/2008.
