Key result
Test procedure:
burning rate test: preliminary screening test
Remarks on result:
not determinable
Remarks:
No propagation of combustion of the test item along 200 mm length of the pile within 4 minutes was observed

The flame of the gas burner did ignite the test item pile. The test item melted, burned with an orange flame and turned into a brown residue. White smoke was observed. After removal of the ignition source, the flame extinguished after 2 seconds and 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.

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

The flammability of the test item (= REACH substance) was determined in a GLP-compliant study performed in accordance with EC A.10 method and UN N.1 method. No propagation of combustion of the test item along 200 mm length of the pile within 4 minutes was observed in the preliminary screening test. 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 flammability of the test item (= REACH substance) was determined in a GLP-compliant study performed in accordance with EC A.10 method and UN N.1 method. No propagation of combustion of the test item along 200 mm length of the pile within 4 minutes was observed in the preliminary screening test. 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

The flammability of the test item was investigated in one GLP-compliant study performed in accordance with standard methods, without deviations. The study is considered as reliable (Klimisch 1) and is selected as a key study for the endpoint

Justification for classification or non-classification

Based on the results obtained with the EC A.10 method, the test item isconsidered ‘not highly flammable’. The test item does not meet the CLP criteria for classification.
