- 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.
Reference
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.

Justification for classification or non-classification
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
