Interpretation of results:
GHS criteria not met
Remarks:
Migrated information
Conclusions:
Guetol has no explosive properties.
Executive summary:

In a GLP study (Defitraces, 2010), the substance Guetol was tested according to EC A14 method, to determine it has explosive properties. The results were the following: 

Mechanical sensitivity (shock):

Six negative assays were recorded: No mechanical sensitivity was noted with the test item.  

Heat sensitivity (flame test) :

Six negative assays were recorded with a tube of 6-mm diameter and with a tube of 2-mm diameter:

No heat sensitivity was noted with the test item.  

In conclusion, the test item Guetol was not considered to have explosive properties according to EC A14 criteria.
