- Rationale for reliability incl. deficiencies:
- guideline study
- Reason / purpose for cross-reference:
- reference to other study
- Qualifier:
- according to guideline
- Guideline:
- other: UN Test 2(b): “Koenen Test”.
- Principles of method if other than guideline:
- See 'Any other information on materials and methods incl. tables'.
- GLP compliance:
- yes (incl. QA statement)
- Parameter:
- thermal sensitivity - Koenen test: diameter of the orifice plate
- Remarks on result:
- negative (not further specified)
- Parameter:
- thermal sensitivity - Koenen test: limiting diameter (mm)
- Remarks on result:
- negative (not further specified)
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- The test substance shows no violent effect on heating under confinement.
- Executive summary:
To determine the sensitivity of the test substance to the effect of intense heat under high confinement a study was performed according to UN Test 2(b): “Koenen Test”. In this study no explosions were observed using 1 mm orifice plates, i.e. Limiting Diameter < 1 mm and the outcome of the test is considered to be “–” (i.e. negative).

RESULTS
No explosions occurred and each test was suspended after a total heating period of 5 minutes.
CONCLUSIONS
- No explosions were observed using the 1 mm orifice plates, i.e. Limiting Diameter < 1 mm.
- In accordance with the criteria of UN Test 2(b), the Limiting Diameter is less than 2 mm and the outcome of the test is considered to be “–” (i.e. negative).
- The test substance shows no violent effect on heating under confinement.
RESULTS
In all three tests the test substance failed to produce pressures greater than the upper threshold of 2070 kPa, in which case the rise times could not be determined. Overall, the highest pressure achieved was 349 kPa.
CONCLUSIONS
- In all three tests, the upper pressure threshold of 2070 kPa was not achieved.
- In accordance with the criteria of UN Test 2(c)(i), the outcome of the test is considered to be “–” (i.e. negative).
- The test substance shows no deflagration when ignited under confinement.
Description of key information
The test substance is not classified as an explosive based on negative findings in tests for effect of heating under confinement ('Koenen test' type 2(b)) and effect of ignition under confinement (time/pressure test type 2(c)).
Key value for chemical safety assessment
- Explosiveness:
- non explosive
Additional information
Test Series 2 from Reference 5.2 has been carried out in order to establish whether or not the test substance is too insensitive for classification as an explosive. This series comprises the following types of test:
- Type 2(a): sensitivity to detonative shock
- Type 2(b): effect of heating under confinement
- Type 2(c): effect of ignition under confinement
Tests of type 2(a) were rendered unnecessary, as the heat of decomposition was determined at <800 J/g. Both the Koenen test (type 2(b)) and the time/pressure test (type 2(c)) produced results which were considered to be “–” (i.e. negative). Therefore the overall conclusion from these tests is that the test substance is not classified as an explosive.
Justification for classification or non-classification
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
