Reference 1

Endpoint:

flammable solids

Type of information:

experimental study

Adequacy of study:

key study

Study period:

From February 09, 2018 to February 09, 2018

Reliability:

1 (reliable without restriction)

Rationale for reliability incl. deficiencies:

guideline study

Qualifier:

according to guideline

Guideline:

UN Manual of Tests and Criteria: Test N.1 (Test method for readily combustible solids)

Deviations:

no

GLP compliance:

yes (incl. QA statement)

Key result

Test procedure:

burning rate test: preliminary screening test

Remarks on result:

other: The test substance could only be ignited locally, with little spreading of the combustion using a flame as ignition source being applied for at least 2 minutes. The sample melted when applying the ignition source.

Preliminary test:

The test substance could only be ignited locally, with little spreading of the combustion using a flame as ignition source being applied for at least 2 minutes. The sample melted when applying the ignition source.

 

The main test:

In the primary test the test substance could only be ignited locally with little spreading of the combustion. Hence the performance of the main test was not necessary.

Interpretation of results:

other: not classified based on CLP criteria

Conclusions:

Under the study conditions, the substance was not classified as a readily combustible solid.

Executive summary:

A study was conducted to determine the flammability of the substance, C18 ADBAC (active: 96.2%) according to the UN Test Method N.1 as described in the UN Recommendations of Dangerous Goods, Manual of Tests and Criterion part III, sub-section 33.2.1.4. The test substance was formed into a mould as per guideline specifications. An ignition source (i.e., a flame) was applied on the test substance until it ignited or for at least 2 minutes. In a preliminary test, the test sample melted, but no propagation or smouldering was observed. From the results of the preliminary screening test, the test substance was found not to ignite and therefore the study author concluded that no further testing was required. Under the study conditions, the substance was not classified as a readily combustible solid (Kremer, 2018)

Key result

Test procedure:

burning rate test: preliminary screening test

Moisture (wt %):

1.96

Remarks on result:

other: Test substance melted and ignited with localised orange flame when in contact with the ignition source, however on removal of the ignition source, the flame extinguished and not propagation or smouldering along the test substance train was observed

Remarks:

No further testing required

Result

The test substance melted and ignited with a localised, orange flame when in contact with the ignition source. On removal of the ignition source the flame extinguished, no propagation or smouldering along the test substance train was observed. As in the preliminary screening test the sample was seen to briefly ignite, the study author concluded that no further testing is required.

Interpretation of results:

other: not classified based on EU CLP criteria

Conclusions:

Under study conditions, the test substance was classified as not highly flammable.

Executive summary:

A study was conducted to determinet the flammability of the test substance, C18 ADBAC (active: 89.5%), according to the EU Method A10, in compliance with GLP. The test substance melted and ignited with a localised, orange flame when in contact with the ignition source. On removal of the ignition source the flame extinguished, no propagation or smouldering along the test substance train was observed. As in the preliminary screening test the sample was seen to only briefly ignite, the study author concluded that no further testing is required. Under study conditions, the test substance was classified as not highly flammable (Chilworth, 2017).

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 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

Description of key information

The flammability of the test substance was determined according to the UN Test Method N.1 (Kremer, 2018) as well as EU Method A.10 (Chilworth, 2017).

Key value for chemical safety assessment

Flammability:

not classified

Additional information

Two studies available with the test substance indicated that it was not highly flammable. The substance only melted and ignited with a localised, flame when in contact with the ignition source. It did not propagate or smoulder.

Justification for classification or non-classification

In a preliminary test, the test sample melted, but no propagation or smouldering was observed. From the results of the preliminary screening test, the test substance was found not to ignite and therefore the study author concluded that no further testing was required. Based on the study result, the test substance was considered as and not highly flammable and not classified based on EU CLP criteria (Regulation 1272/2008/EC).
