Conclusions:
The test substance is not highly flammable.
Executive summary:

The objective of the study was to determine the flammability of the test substance according to EU method A.10. The preliminary screening test was made to determine if, on ignition by a gas flame, propagation by burning with flame or smouldering occurs. It was noted whether combustion propagates along 200 mm of the train within the 4 minutes test period. The substance was formed into an unbroken strip or powder train about 250 mm long by 20 mm wide by 10 mm high on a non-combustible, non-porous and low heat-conducting base plate. A hot flame from a gas burner (minimum diameter 5 mm, temperature of the flame was about 1000 °C) was applied to one end of the powder train until the powder ignites or for a maximum of 2 minutes. The test substance melts after the application a gas flame. The substance does not ignite. The test substance is not highly flammable.

Description of key information

Key study. EU method A.10. GLP study. 
The test substance is not highly flammable. 
Data waiving: For the test substance pyrophoricity and flammability in contact with water can be excluded since the experience in manufacture and handling shows that the substance does not ignite spontaneously on coming into contact with air at normal temperatures. Additionally, there are no functional groups within the test item molecule that could cause pyrophoricity or flammability in contact with water, basis: "Guidance on information requirements and chemical safety assessment", Chapter R.7a: Endpoint specific guidance, R.7.1.10.3 and table R.7.1-27 (ECHA, May 2008).
