Dodecamethylenediamine

Flammability

Link to relevant study record(s)

Reference

Reference 1

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 2

Endpoint:

pyrophoric solids

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

Endpoint:

flammable solids

Type of information:

experimental study

Adequacy of study:

key study

Study period:

17. December 2018 - 26. February 2019

Reliability:

1 (reliable without restriction)

Rationale for reliability incl. deficiencies:

guideline study

Qualifier:

according to guideline

Key result

Test procedure:

burning rate test: preliminary screening test

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

Interpretation of results:

GHS criteria not met

Conclusions:

the test item 1,12-Diaminododecane should be considered as
not highly flammable (for EU regulations)
non-flammable solid (for UN regulations)

Executive summary:

First, a safety test was performed. A small amount of the test item was heated on a magnesia

groove with a gas burner in order to derive safety precautions. The test item melted to a

colourless liquid and burned with an orange flame.

In the preliminary screening test following the EU and the UN method, the test item was

heated with the flame of a teclu burner. The test item just melted to a colourless to slightly

white liquid. No ignition occurred within two minutes.

Therefore, the test item 1,12-Diaminododecane should be considered as

not highly flammable (for EU regulations)

non-flammable solid (for UN regulations)

Description of key information

a preliminary screening test for flammability is available.

Experience from handling and production indicates no pyrophoric properties

and stability in water.

Key value for chemical safety assessment

Flammability:

not classified

Justification for classification or non-classification

The available information is conclusive but not sufficient for classification.
