Preliminary test

The test item was formed into an unbroken strip or powder train, approximately 250-mm long, 20-mm wide and 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) was applied to one end of the powder train until ignition or for a maximum of 2 min. It was noted whether combustion propagates along 200 mm of the train within the 4-min test period.

- If the test item does not ignite and propagate combustion, either by burning with flame or smouldering along 200 mm of the powder train within the 4-min test period, the test item is not considered as highly flammable and no further testing is performed.

- If the test item propagated burning over a 200-mm length of the powder train in less than 4 min a main test (burning rate test) is carried out.

Interpretation of results:
non flammable
Remarks:
Migrated information
Conclusions:
The test DETU (1,3-diethyl-2-thiourea CAS 105-55-5) is not considered as highly flammable under our experimental conditions.
Executive summary:

According to an OECD A10 test made by DEFITRACE on DETU (1,3 -diethyl-2 -thiourea, CAS 105 -55 -5) :

The test item has melted and formed a colourless limpid liquid that evaporates. Any ignition or spread.

The test item was not considered as highly flammable under our experimental conditions.
