- Remarks on result:
- other: result not specified (migrated information) TBS did not burn, but evaporated out of the cellu lose to leave a charred solid
- Sample tested:
- test mixture (not specified)
- Parameter:
- maximum burning rate
- Result:
- 97 s
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- TBS is non-flammable and lacking oxidising groups in the molecule, there is no realistic possibility that TBS presents an Oxidation hazard.
- Executive summary:
The oxidising properties of TBS were assessed as described in EEC A17. TBS did not burn but evaporated out of the cellulose. TBS is non-flammable and lacking oxidising groups in the molecule,there is no realistic possibility that TBS presents an Oxidation hazard.
Reference
The molecular structure of TBS does not contain any oxidising groups such as peroxide, chlorate, perchlorate, nitrate, bromate, chromate, etc. Therefore, in our considered opinion, there is no realistic possibility that the formulation presents an Oxidation hazard. In order to reinforce the above statement, oxidising property determinations were carried out according to the preliminary determination given in EEC A17.
TBS did not burn, but evaporated out of the cellulose to leave a charred solid
The efficacy of the method was tested, as described in the method, using a 60:40 reference mix of Barium Nitrate: Cellulose. A cone was prepared, as above, and placed on the platinum wire. The standard specimen exhibited a vigorous reaction with a steady fame. Reaction completed in approximately 1 minute 37 seconds.
Description of key information
The substance does not contain any oxidising groups and, although it is flammable, does not present an oxidation hazard.
Key value for chemical safety assessment
- Oxidising properties:
- non oxidising
Additional information
Justification for classification or non-classification
No oxidising groups present and does not meet the criteria when tested according to EEC A17.
