- Lot/batch No.of test material: E01255-297
- Expiration date of the lot/batch: 31 December 2022

Key result

Test procedure:

burning rate test: preliminary screening test

Burning time:

2 s

Remarks on result:

substance does not ignite and propagate combustion either by burning with flame or smouldering along 200 mm of the powder train within the 2 minutes test period

The flame of the gas burner did ignite the test item pile. The test item melted, burned with a yellow/blue flame and turned into a dark brown residue. White smoke was observed. After removal of the ignition source, the flame extinguished after 2 seconds and no propagation of combustion was observed.

Interpretation of results:

not classified based on GHS criteria

Conclusions:

The preliminary screening test was performed for the determination of the flammability of the test item. The flame of the gas burner did ignite the test item pile. The test item melted, burned with a yellow/blue flame and turned into a dark brown residue. White smoke was observed. After removal of the ignition source, the flame extinguished after 2 seconds and no propagation of combustion was observed. Overall, 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 study was performed based on procedures in the UN Manual of Tests and Criteria: Test N.1 (Test method for readily combustible solids). The preliminary screening test was performed for the determination of the flammability of the test item. The flame of the gas burner did ignite the test item pile. The test item melted, burned with a yellow/blue flame and turned into a dark brown residue. White smoke was observed. After removal of the ignition source, the flame extinguished after 2 seconds and no propagation of combustion was observed. Overall, 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’.
