Endpoint:

flammable solids

Type of information:

experimental study

Adequacy of study:

key study

Study period:

From 2020-12-21 to 2021-01-07

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:

no

Specific details on test material used for the study:

Batch No.: 465884
Purity: 100%

Test procedure:

burning rate test: preliminary screening test

Remarks on result:

other: No propagation of combustion of the test item along 200 mm length of the pile within 2 minutes was observed.

The flame of the gas burner did ignite the test item pile. The test item melted, burned with a blue yellow flame, emitted yellow sparks and turned into an orange brown residue. Grey smoke was observed. After removal of the ignition source, the flame extinguished after 1 second and no propagation of combustion was observed.

Interpretation of results:

not classified based on GHS criteria

Conclusions:

No propagation of combustion of the test item along 200 mm length of the pile within 2 minutes was observed. According to the guidelines, performance of the burning rate test is not required. Based on the results obtained, the test item is considered ‘not flammable’.

Executive summary:

The preliminary screening test was performed for the determination of the flammability of test item according to UN N.1.

No propagation of combustion of the test item along 200 mm length of the pile within 2 minutes was observed. According to the guidelines, performance of the burning rate test is not required. Based on the results obtained, the test item is considered ‘not flammable’.

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

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 organic substance does not contain metals or metalloids and hence, the classification procedure does not need to be applied

Description of key information

Flammable solids:

The preliminary screening test was performed for the determination of the flammability of test item according to UN N.1. No propagation of combustion of the test item along 200 mm length of the pile within 2 minutes was observed. The test item is considered ‘not flammable’.

 

Pyrophoric solids:

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.

 

Flammability in contact with water:

The study does not need to be conducted because the organic substance does not contain metals or metalloids and hence, the classification procedure does not need to be applied.

Key value for chemical safety assessment

Flammability:

not classified

Justification for classification or non-classification

Flammable solids:

Flammability, UN N.1, not flammable: No propagation of combustion of the test item along 200 mm length of the pile within 2 minutes was observed.

In accordance with Regulation (EC) No. 1272/2008, table 2.7.1, the substance should not be classified for this endpoint.

 

Pyrophoric solids:

In accordance with Regulation (EC) No. 1272/2008 section 2.10.4.1, the classification procedure for pyrophoric solids need not be applied when experience in manufacture or handling shows that the substance or mixture does not ignite spontaneously on coming into contact with air at normal temperatures (i.e. the substance is known to be stable at room temperature for prolonged periods of time (days)). As the substance is known to be stable in contact with air at room temperature for prolonged periods of time (days), so the classification procedure for pyrophoric solids does not need to be applied.

 

Substances and mixtures which in contact with water emit flammable gases:

In accordance with Regulation (EC) No. 1272/2008 section 2.12.4.1 (a), the classification procedure for this class need not be applied if the chemical structure of the substance or mixture does not contain metals or metalloids. As no metals or metalloids present in the molecule of this substance, so the classification procedure for this class need not be applied for this substance.
