Test procedure:

burning rate test: preliminary screening test

Burning time:

< 178 s

Key result

Test procedure:

burning rate test over 100 mm length

Burning time:

> 92 s

In the 'Preliminary Screening Test', it was observed that, the test item powder train ignited after 2 seconds of application of hot flame from the gas burner and the test item powder train burnt upto 20 cmin less than 4 minutes (178 seconds). In the view of the 'Preliminary Screening Test', it was concluded that dibenzetano crystallized is Flammable.

The burning rate test was carried out to confirm the results obtained in the preliminary test.

The burning time of 10 cm test item powder train was 89, 95, 93, 85, 90 and 102 seconds for replications I, II, III, IV, V and VI, respectively.

The mean burning time of all the six tests (10 cm powder train) was 92 seconds (whichis morethan 45 seconds).

In the view of the burning rate test, it was concluded that dibenzetano crystallized is Non-flammable.

Interpretation of results:

not classified based on GHS criteria

Conclusions:

Dibenzetano crystallized is ‘Non-flammable’.

Description of key information

Based on the results of the Burning Rate Test, it was concluded that dibenzetano crystallized is Non-flammable.
