Preliminary Test:
In the preliminary test, the spread of the combustion over about 30 mm in 120 s could be detected. The flame went out multiple times.
Main Test:
In the preliminary test the test item did only burn over a distance of 30 mm in 120 s. Thus, the performance of the main test was not necessary.
The following Table 2 shows the results of the tests with the test item was poured from approximately 1 meter high onto a non-combustible surface at ambient temperature.
