Reference
Endpoint:
explosive properties of explosives
Type of information:
experimental study
Adequacy of study:
key study
Study period:
05 March 1993
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
comparable to guideline study with acceptable restrictions
Qualifier:
equivalent or similar to guideline
Guideline:
EU Method A.14 (Explosive properties)
Principles of method if other than guideline:
Hartmann Rohr for the determination of dust-explosive properties
DSC to evaluate the exothermal energy
GLP compliance:
no
Parameter:
other: DSC
Remarks on result:
not thermal sensitive if heated under defined confinement
Remarks:
The energy set free in the DSC was 50 J/g and 240 J/g. As the exothermal energy is below 500 J/g, the explosive properties of the substance has not to be further investigated.

Dust explosion properties:

Pmax 5.6 bar, Kst 14 bar.m/s, tested in 20L bowl

Dust explosion class St 1, Ignition energy 1000 J

Interpretation of results:
GHS criteria not met
Conclusions:
The exothermal energy in the DSC is below 500 J/g, hence the substance does not have explosive properties.
The test substance has no danger of explosion according to the explosive properties when tested in the modified Hartmann Rohr.
Executive summary:

The exothermal energy in the DSC is 50 and 240 J/g (< 500 J/g), hence the substance does not have explosive properties.


The test substance has no danger of explosion according to the explosive properties when tested in the modified Hartmann Rohr. Dust concentrations of 30 g/m³, 100 g/m³, 200 g/m³, 500 g/m³ and 1000 g/m³ have been tested.

Description of key information

Non explosive when tested for relevant safety indicators.

Key value for chemical safety assessment

Explosiveness:
non explosive

Additional information

The exothermal energy in the DSC is 50 and 240 J/g (< 500 J/g), hence the substance does not have explosive properties.


The test substance has no danger of explosion according to the explosive properties when tested in the modified Hartmann Rohr. Dust concentrations of 30 g/m³, 100 g/m³, 200 g/m³, 500 g/m³ and 1000 g/m³ have been tested.
