METHOD MECHANICAL SENSITIVITY (SHOCK):
The thermogram shows an endothermic peak at 140 °C, which is attributed to melting, followed by two broad, very similar exothermic peaks at 240 °C and 346 °C. The total normalized energy output from these exothermic events, i.e. the heat of decomposition, is 770 J/g.
To conclude:
(i) The heat of decomposition of the test substance = 770 J/g.
(ii) The heat of decomposition is greater than 500 J/g, in which case further explosive testing will be required to establish the sensitivity of the test substance to heating and ignition under confinement.
(iii) The heat of decomposition is less than 800 J/g, in which case the explosive test to establish the sensitivity to detonative shock will not be required.
KOENEN TEST
The results of the three tests carried out on the test substance are tabulated below, where O = Tube recovered unchanged, t1 = Time elapsed from ignition of burners to the first noticeable reaction of the test substance, and t2 = Time elapsed from t1 to the end of the reaction.
Table 1: Koenen test
Test Number | Orifice Diameter | Tube Condition | t1 (s) | t2 (s) |
1. | 1 mm | O | 14 | 169 |
2. | 1 mm | O | 11 | 189 |
3. | 1 mm | O | 11 | 219 |
Note: In the absence of a positive result using the 1 mm orifice, no further tests at larger orifice diameters were required.
Comments:
(a) During each test, after a time t1 and lasting for a time t2, test material vented with flame through the orifice.
(b) No explosions occurred and each test was suspended after a total heating period of 5 minutes.
To conclude:
(i) No explosions were observed using the 1 mm orifice plates, i.e. Limiting Diameter < 1 mm.
(ii) 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).
(iii) The test substance shows no violent effect on heating under confinement.
TIME/PRESSURE TEST
The results of the three tests carried out on the test substance are tabulated below, where
O = Tube recovered unchanged,
t1 = Time elapsed from ignition of burners to the first noticeable reaction of the test substance,
and t2 = Time elapsed from t1 to the end of the reaction.
Test No. | Rise Time (s) | Maximum Pressure (kPa) |
1. | - | 258 |
2. | - | 304 |
3. | - | 232 |
To conclude:
(i) In all three tests, the upper pressure threshold of 2070 kPa was not achieved.
(ii) In accordance with the criteria of UN Test 2(c)(i), the outcome of the test is considered to be “–” (i.e. negative).
(iii) The test substance shows no deflagration when ignited under confinement.
Test Series 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 (less than 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).
Description of key information

Justification for classification or non-classification
Based on the available information, classification on explosiveness is not warranted in accordance with EU Classification, Labelling and Packaging of Substances and Mixtures (CLP) Regulation No. (EC) 1272/2008.
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).
