Description of key information
Supporting study:
In the GLP compliant study according to UN Transport Regulations test series 1-8 was conducted with the test substance in solution (55%) in order to classify this preparation according to the UN procedure for assignment to a division of Class 1. Based on the outcome of the studies the test substance in solution (55%) has not to be classified as explosive according to UN GHS and regulation (EC) No 1272/2008 (CLP).
Key value for chemical safety assessment
- Explosiveness:
- non explosive
Additional information
Preliminary DSC measurements
In four different DSC-measurements (BASF SE, SIK Nr. 01/0983, 01/0984, 05/2322 and 16/0084 Please refer to IUCLID section 4.19) the heat of descomposition was determined to be greater than 1480 J/g (2400, 2800, 3190 and 1480 J/g) with an onset temperature of 280 °C (200, 190, 200 and 280 °C). Thus further testing with regard to explosive properties was required.
The results from the application of the class 1 acceptance procedure were as follows:
For safety reasons the sensitivity to impact and friction (as part of test series 3) was tested in a preliminary test.
Preliminary test
Sensitivity to impact and friction: Test 3(a)(ii) BAM Fallhammer (D)
Observation: no explosion or flames observed using an impact engery of 40 J Result: not sensitive to impact using an impact energy of 40 J
Explosive power: Test F3: BAM Trauzl test
Observation: Expansion of 1.3 cm3 per 10 g.
Result “No”
Box 2: Is the substance manufactured with the view to producing a practical explosive or pyrotechnic effect?
Answer: No
Exit: Go to Box 3
Box 3: Test Series 1
Propagation of detonation: Test 1 (a) UN Gap test (UN)
Test omitted according to Appendix VI of UN RTDG MTC as the outcome of the Test F3: BAM Trauzl test is “no”.
Result “-“
Effect of heating under confinement: Test 1 (b) Koenen test (D)
Observation: There is no effect from intensively heating the substance under hight confinement.
Result: “-“,no effect from intensively heating the substance under high confinement
Effect of ignition under confinement: Test 1 (c) Time/pressure test (GB)
Observation: The maximum pressure reached in any one test is less than 2070 kPa gauge.
Result: “-“,The substance show not the ability to deflagrate
Box 4: Is it an explosive substance
Answer: No
Exit: Go to Box 7
Box 5: Test Series 2
Propagation of detonation: Test 1 (a) UN Gap test (UN)
Test omitted according to Appendix VI of UN RTDG MTC as the outcome of the Test F3: BAM Trauzl test is “no”.
Effect of heating under confinement: Test 2 (b) Koenen test (D)
Observation: There is no violent effect from intensively heating the substance under high confinement.
Result: “-“,no violent effect from intensively heating the substance under high confinement
Effect of ignition under confinement: Test 2 (c) Time/pressure test (GB)
Observation: The maximum pressure reached in any one test is less than 2070 kPa gauge
Result: “-“,The substance shows slow or no deflagration ("-").
Exit: Go to Box 7
Box: 7
Result: Not class 1
UN procedure for assignment to a division of Class 1 the test substance is not considered to exhibit a danger of explosion. The result does not lead to a classification in Class 1.
Justification for classification or non-classification
The available experimental test data are reliable and suitable for classification purposes under Regulation 1272/2008. The test substance is not considered to exhibit a danger of explosion. As a result the substance is not considered to be classified for explosiveness under Regulation (EC) No 1272/2008, as amended for the eighth time in Regulation (EU) No 2016/218.
