Adequacy of study:

key study

Reliability:

1 (reliable without restriction)

Rationale for reliability incl. deficiencies:

guideline study

Qualifier:

according to guideline

Guideline:

EU Method A.10 (Flammability (Solids))

Cited as Directive 92/69/EEC, A.10

Deviations:

no

GLP compliance:

yes (incl. QA statement)

Key result

Test procedure:

burning time (test type not further specified)

Burning time:

> 120 s

DDAC was inflammable within 2 min by the hot flame of a gas burner but did not spread out over a distance of 200 mm
within 4 min. DDAC has to be considered as not highly flammable according to the criteria of the test guideline.

Interpretation of results:

other: CLP criteria not met

Conclusions:

DDAC was inflammable within 2 min by the hot flame of a gas burner but did not spread out over a distance of 200 mm within 4 min. DDAC does not need to be classified as highly flammable.

Executive summary:

The flammability of the test substance was determined according to EU method A10. In this study, the flammability potential was determined by ignition of a cluster with a length of 250 mm, a width of 20 mm with hot flame of a gas burner. The test substance was inflammable within 2 min by the hot flame of a gas burner but did not spread out over a distance of 200 mm within 4 min. Therefore, the test substance does not need to be classified as highly flammable (Schulze, 2006).

Test procedure:

burning time (test type not further specified)

Burning time:

ca. 120 s

Remarks on result:

other: There was no inflammation observed within 2 min

The test substance began to melt immediately after it was tried to ignite the pile with a hot flame from a gas burner. There was no inflammation observed within 2 min. Because it was impossible to ignite the test substance the main test had not to be performed.

Interpretation of results:

other: CLP criteria not met

Conclusions:

The test substance is not inflammable.

Executive summary:

The test was performed as described in EU method A10. A non-combustible source and a teclu-burner was used for ignition. The sample of the test substance was carried over onto a certain plate as described in the method. The substance cord was tried to ignite at one end using the burner. The test substance began to melt immediately after it was tried to ignite the pile with a hot flame from a gas burner. There was no inflammation observed within 2 min. Because it was impossible to ignite the test substance the main test had not to be performed. Therefore the test substance is classified to be not inflammable according to EEC-Guideline A.10 ( Keipert, 2001)..

Description of key information

Two studies were performed to determine the flammability of the solid form of the test substance according to EU Method A.10 (Keipert, 2001 and Schulze, 2006).

Key value for chemical safety assessment

Flammability:

flammable

Additional information

The solid form of the test substance was found to be flammable under the test conditions but did not fulfil criteria for classification as flammable. However, the liquid form of the substance was found to have a flash point of 26.4°C, suggesting flammability potential.

Justification for classification or non-classification

Based on the results from studies conducted according to EU Method A.10, the solid form of the test substance does not warrant a classification for flammability according to EU CLP criteria (Regulation EC 1272/2008). However, the liquid form of the substance was found to have a flash point of 26.4°C, which warrants a classification as Flam. Liquid. 3- H226 (Flammable liquid and vapour) according to EU CLP criteria (Regulation EC 1272/2008).
