Reference

Reference 1

Endpoint:

flammable solids

Type of information:

experimental study

Adequacy of study:

key study

Study period:

August 12, 2010

Reliability:

1 (reliable without restriction)

Rationale for reliability incl. deficiencies:

guideline study

Qualifier:

according to guideline

Guideline:

EU Method A.10 (Flammability (Solids))

Deviations:

no

Principles of method if other than guideline:

The substance is formed into an unbroken strip or powder train about 250 mm long and a preliminary screening test performed to determine if, on ignition by a gas flame, propagation by burning with flame or smoldering occurs. If propagation over 200 mm of the train occurs within a specified time then a full test program to determine the burning rate is carried out.

GLP compliance:

no

Key result

Test procedure:

burning rate test: preliminary screening test

Remarks on result:

other: In the screening test, the part of the test substance that was exposed to the flame melted and ignited, but no propagation of combustion occurred. This means that the substance is not considered as highly flammable and that no further testing is required.

Interpretation of results:

other: not classified based on CLP criteria

Conclusions:

Under the study conditions, the test substance was considered to be non-flammable.

Executive summary:

A study was conducted to determine the flammability potential of the test substance, C16 -18 ADBAC (98.2% active) according to EU Method A.10. In the screening test the gas flame was applied for 2 minutes to one end of the substance train. The part of the test substance that was exposed to the flame melted and ignited, but no propagation of combustion occurred. Therefore, the substance is not considered as highly flammable and that no further testing is required. Under the study conditions, the test substance was considered to be non-flammable (Nagelhout, 2010).

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 3

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 was determined according to EU Method A.10 (Negelhout, 2010).

Key value for chemical safety assessment
