Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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:
From 2020-02-13 to 2020-04-22
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
Qualifier:
according to guideline
Guideline:
other: OECD 113 Screening test for thermal stability and stability in air
Deviations:
no
GLP compliance:
yes (incl. QA statement)
Key result
Parameter:
other: DSC
Remarks on result:
other: Two DSC measurements in closed glass crucibles showed an endothermal effect in the temperature range of 100-135°C and an exothermal effect in the temperature range of 235 - 470°C with a maximum energy release of 752 J/g.
Key result
Parameter:
sensitiveness to friction: friction load (N)
Remarks on result:
not sensitive to friction using a friction load of 360 N
Remarks:
The test item was sieved (mesh size 0.5 mm) before the measurement. No explosion occurred within 6 tests using a pinload of 360 N, only a discoloration of the test item into dark brown was observed in all tests.
Key result
Parameter:
sensitiveness to impact: impact energy (J)
Remarks on result:
other: The test item was sieved (mesh size 0.5 mm) before the measurement. No explosion within 6 tests using a mass of 10 kg falling from a height of 0.4 m was observed.
Key result
Parameter:
thermal sensitivity - Koenen test: diameter of the orifice plate
Remarks on result:
not thermal sensitive if heated under defined confinement
Remarks:
Three tests were performed with a circular nozzle plate with a hole of 2 mm diameter. No explosion was observed.

The test on thermal sensitivity carried out with a nozzle with a diameter of 2.0 mm showed no explosion. Compared to the nozzle with a diameter of 6.0 mm the venting area of the nozzle with 2.0 mm is smaller by an order of magnitude. Additionally, the physical state of the test item excludes the enrichment of high-energy components caused by evaporation of volatile solvents. Due to these facts an explosion with a nozzle width of 6.0 mm was excluded.

Interpretation of results:
GHS criteria not met
Conclusions:
The test item had no explosive properties in the sense of the European Commission Regulation (EC) No. 440/2008, Method A.14.
Executive summary:

The aim of the test was to determine the explosive properties of the test item according to the OECD 113 guideline/ A.14 method (thermal sensitivity, sensitivity to shock, sensitivity to friction) and following GLP. The test item had no explosive properties in the sense of the European Commission Regulation (EC) No. 440/2008, Method A.14.
