Qualifier:
according to
Guideline:
EU Method A.10 (Flammability (Solids))
Deviations:
no
Qualifier:
according to
Guideline:
UN Manual of Tests and Criteria: Test N.1 (Test method for readily combustible solids)
Deviations:
no
GLP compliance:
yes (incl. certificate)
Test procedure:
burning rate test: preliminary screening test
Burning time:
< 4 min

The flame of the gas burner did ignite the test item pile. The test item burned with an orange flame and turned into a black residue. White smoke was observed. After removal of the ignition source, the flame extinguished after 50 seconds and no propagation of combustion was observed.

Interpretation of results:
not classified based on GHS criteria
Conclusions:
The test item is considered ‘not highly flammable’.
Executive summary:

The preliminary screening test was performed for the determination of the flammability of the test item according to EU Method A.10 and UN Test N.1. No propagation of combustion of the test item along 200 mm length of the pile within 4 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 highly flammable’.

Description of key information

The preliminary screening test was performed for the determination of the flammability of the test item according to EU Method A.10 and UN Test N.1. No propagation of combustion of the test item along 200 mm length of the pile within 4 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 highly flammable’.

Key value for chemical safety assessment

Flammability:
not classified

Additional information

One reliable experimental study is available and is selected as key study (Charles River, 2018). It was performed according to EU Method A.10 and UN Test N.1, and under GLP principles.

Justification for classification or non-classification

Based on the results obtained in the key study (EU A10 and UN N1 method used), the test item is considered as non flammable
