Key result

Test procedure:

burning rate test: preliminary screening test

Burning time:

ca. 5 - ca. 10 s

Moisture (wt %):

37

Remarks on result:

other: The melt ignited locally several times for approx. 5 to 10 s

Remarks:

Main test was not neccesary to be performed

Results

 

Preliminary Test

The test substance melted at room temperature using a flame as ignition source being applied for at least 2 minutes. During the two minutes, the melt ignited locally several times for approx. 5 to 10 s.

 

Main Test

In the preliminary test the test substance melted and could locally be ignited by a flame for a few seconds. Thus, the performance of the main test was not necessary.

 

Final Results

The pasty test substance could locally be ignited applying a flame as ignition source for at least 2 minutes. The test substance melted and did not burn over the whole length of the line. The test substance is classified as follows:

UN Transport Regulation: The pasty product has not to be classified as readily combustible solid in class 4.1 according to the UN Transport Regulation.

GHS (CLP Regulation EC 1272/2008: Annex 1: 2.7): The pasty product has not to be classified as flammable solid according to GHS / CLP Regulation EC 1272/2008 Annex 1: 2.7.

Interpretation of results:

other: not classified based on EU CLP criteria

Conclusions:

Under the study condition, the test substance was determined to be not highly flammable.

Executive summary:

A study was conducted to determine the flammability of the test substance (Purity: 61%), according to UN Transport Regulation (Class 4, Division 4.1) and GHS / CLP Regulation EC 1272/2008 (Annex 1: 2.7), in compliance with GLP. During the preliminary test, the test substance melted at room temperature using a flame as ignition source being applied for at least 2 minutes. During the two minutes, the melt ignited locally several times for approx. 5 to 10 s. The test substance melted and did not burn over the whole length of the line. Therefore, the study author decided that the performace of the main test was not necessary. Under the study condition, the test substance was determined to be not highly flammable (Moller, 2018).

Reference 2

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

Flammability of the test substance was determined, according to method described in UN Transport Regulation (Class 4, Division 4.1) and GHS / CLP Regulation EC 1272/2008 (Annex 1: 2.7) (Moller, 2018).

Key value for chemical safety assessment

Flammability:

not classified

Justification for classification or non-classification

In a preliminary test, the test substance, melted and ignired locally several times for approx. 5 to 10 s, but did not burn over the whole length of the line. Therefore, test substance is concluded not to warrant classification for flammability according to EU CLP criteria (Regulation 1272/2008/EC).
