flammable solids

Type of information:

experimental study

Adequacy of study:

key study

Study period:

January 2018

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

GLP compliance:

no

Other quality assurance:

other: ISO 9001-2015

Key result

Test procedure:

burning rate test: preliminary screening test

Burning time:

ca. 19.5 min

Moisture (wt %):

10

Remarks on result:

other: The test material does not propagate combustion (either by burning with flame or smoldering) along 200 mm of the sample strip within the test period of 4 minutes.

Remarks:

Consequently, the test material does not propagate combustion (either by burning with flame or smoldering) along 200 mm of the sample strip within the test period of 4 minuThe test substance is not considered as highly flammable

In the screening test the gas flame was applied to one end of the substance strip. The test substance ignited and continued burning for 19.5 minutes and stopped burning. Consequently, the test substance did not propagate combustion (either by burning with flame or smoldering) along 200 mm of the sample strip within the test period of 4 minutes. Based on the study result, the study author concluded that the test substance is not considered as highly flammable according to EU A.10 Method.

Interpretation of results:

other: not classified based on EU CLP criteria

Conclusions:

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

Executive summary:

A study was conducted to determine the flammability of the test substance, TMAC S (88.3% active), according to the EU Method A10, in compliance with ISO 9001-2015. In the screening test the gas flame was applied to one end of the substance strip. The substance ignited and continued burning for 19.5 minutes and stopped burning. Consequently, the test substance did not propagate combustion (either by burning with flame or smoldering) along 200 mm of the sample strip within the test period of 4 minutes. Based on the study result, the study author concluded that the test substance is not considered as highly flammable according to EU A.10 Method. Under the study conditions, the test substance was considered as not highly flammable (Post, 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 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 EU Method A.10 (Post, 2018).

Key value for chemical safety assessment

Flammability:

not classified

Additional information

In the screening test the gas flame was applied to one end of the substance strip. The substance ignited and continued burning for 19.5 minutes and stopped burning. Consequently, the test substance did not propagate combustion (either by burning with flame or smouldering) along 200 mm of the sample strip within the test period of 4 minutes. Under the study conditions, the test substance was considered as not highly flammable (Post, 2018).

Justification for classification or non-classification

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