Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Reference
Endpoint:
explosive properties of explosives
Type of information:
experimental study
Adequacy of study:
key study
Study period:
1987
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
guideline study
Qualifier:
according to guideline
Guideline:
EU Method A.14 (Explosive properties)
Deviations:
no
GLP compliance:
yes
Key result
Parameter:
thermal sensitivity - Koenen test: limiting diameter (mm)
Remarks on result:
not thermal sensitive if heated under defined confinement
Key result
Parameter:
sensitiveness to impact: impact energy (J)
Remarks on result:
not sensitive to impact using an impact energy of 40 J
Key result
Parameter:
sensitiveness to friction: friction load (N)
Remarks on result:
sensitive to friction

The substance was found to be sensitive to friction (according to the criteria of Annex V) in one of four tests but overall the UK c.a. considers that the substance is not 'explosive' as defined. When first tested, the substance gave a positive result in the friction test. However, three repeat tests (using the same batch) were all negative (two of the tests were performed by different test houses). Therefore, the UK c.a. considered that the notifier has provided sufficient additional data to justify not labelling the substance as explosive.

Interpretation of results:
GHS criteria not met
Conclusions:
The substance can be classified as not explosive under the conditions of this test.
Executive summary:

The study was performed following EU-testing method A.14. The substance was found to be not sensitive to heat and impact, whereas the substance was found to be sensitive to friction (according to the criteria of Annex v) in one of four tests but overall the UK c.a. considers that the substance is not 'explosive' as defined. When first tested, the substance gave a positive result in the friction test. However, three repeat tests (using the same batch) were all negative (two of the tests were performed by different test houses). Therefore, the UK c.a. considered that the notifier has provided sufficient additional data to justify not labelling the substance as explosive.
