Reference 1

Endpoint:

flammable solids

Type of information:

experimental study

Adequacy of study:

key study

Study period:

2007

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:

; cited as Directive 92/69/EEC, A.10

Principles of method if other than guideline:

Not applicable

GLP compliance:

yes (incl. QA statement)

Key result

Test procedure:

burning time (test type not further specified)

Burning time:

< 120 s

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 test substance can be considered as not highly flammable according to the criteria of the test guideline.

Conclusions:

Under the study conditions, the test substance does not need to be classified as highly flammable.

Executive summary:

A study was conducted to determine the flammability of the test substance, DDAC (99.8% active) according to EU method A.10, in compliance with GLP. It was started by the ignition of a line of test substance with a length of 250 mm, a width of 20 mm and a height of 10 mm with the 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. Under the study conditions, the test substance does not need to be classified as highly flammable (Schulze, 2007).

Based on the results of the read across study, the test substance is considered to be non-flammable.

Reference 3

Endpoint:

substances / mixtures which in contact with water emit flammable gases

Data waiving:

study scientifically not necessary / other information available

Justification for data waiving:

the study does not need to be conducted because the experience in production or handling shows that the substance does not react with water, e.g. the substance is manufactured with water or washed with water

Reference 4

Endpoint:

pyrophoric liquids

Data waiving:

study scientifically not necessary / other information available

Justification for data waiving:

the study does not need to be conducted because the substance is known to be stable in contact with air at room temperature for prolonged periods of time (days) and hence, the classification procedure does not need to be applied

Description of key information

The flammability of the read across substance, DDAC, was determined according to EU Method A.10 (Schulze, 2007). 

Key value for chemical safety assessment

Flammability:

not classified

Additional information

The structurally similar substance DDAC (CAS No. 7173-51-5), 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 (Schulze M, 2007). Thus, the test substance, C12 -18 DAQ does not need to be classified as highly flammable.

Justification for classification or non-classification

Based on the results from the read across study, the test substance does not warrant a classification for flammability according to EU CLP criteria (Regulation EC 1272/2008).
