SOURCE OF TEST MATERIAL
- Batch No.of test material: 24/02/2016

STABILITY AND STORAGE CONDITIONS OF TEST MATERIAL
- Storage condition of test material: In darkness at room temperature
Key result
Parameter:
thermal sensitivity - Koenen test: limiting diameter (mm)
Value:
1
Remarks on result:
not thermal sensitive if heated under defined confinement
Key result
Test series:
UN Test series 1
Method:
UN Test 1 (b): Koenen test
Parameter:
limiting diameter (mm)
Value:
1
Result:
result is considered "-" (negative)

As a results, The limiting diameter of a substance is the largest diameter of the orifice at which the result “explosion” was obtained. If no “explosion” was obtained with a diameter of 1.0 mm, the limiting diameter was recorded as being less than 1.0 mm.

- In the Assay with orifice plate of 20.0 mm: the result "O" Tube unchanged was observed after 5 min.

- In the series with orifices plates of 12.0 - 8.0 - 5.0 - 3.0 - 2.0 - 1.5 - 1.0 mm, the results "O" Tube unchanged were observed after 5 min for each nozzle plate opening.

Interpretation of results:
GHS criteria not met
Conclusions:
The result was considered “negative” and the substance has shown no effecton heating under confinement as the limiting diameter was less than 1.0 mm.
Executive summary:

The sensitiveness of a test item to the effect of intense heat under high confinement was determined according the

United Nations Recommendations on the Transport of Dangerous Goods Manual of Tests and Criteria - Sixth revised edition (2015) Series 1 type (b) Test 1 (b) (Part I, Section 11.5.1) EC No. 1272/2008 (CLP) and ubder GLP compliance.

In the Assay with orifice plate of 20.0 mm and in series with orifices plates of 12.0 - 8.0 - 5.0 - 3.0 - 2.0 - 1.5 - 1.0 m, the results "O" Tube unchanged were observed after 5 min for each nozzle plate opening.

Therefore the result was considered “negative” and the substance has shown no effecton heating under confinement as the limiting diameter was less than 1.0 mm.

no guideline followed
Principles of method if other than guideline:
The objective of the test is to determine the behaviour of the test item during a heating procedure within a nitrogen atmosphere and at the atmospheric pressure using the Differential Scanning Calorimetry method (DSC). This thermodynamic information allows determining if the test item gives exothermic reactions upon heating and thus a more complete test on explosive properties is relevant.

Description of key information

Three reliable studies performed according to guidelines from the UN Recommendations on the Transport of Dangerous Good, Manual of Tests and Criteria, test series 1 and 3 were performed. The tests were GLP compliant.

In the Koenen test the substance has shown no effect on intense heating under high confinement as the limiting diameter was less than 1.0 mm.

In the Bam Fallhammer test the substance has shown no effect to the shock of a falling hammer on a steel anvil.

A test using the Differential Scanning Calorimetry method (DSC) was performed in order to determined the behaviour of the test item during a heating procedure within a nitrogen atmosphere and at the atmospheric pressure. In this test, in the temperature range used, no exothermic reaction was observed.

Basing on the results on the tests, the substance is not be classified as explosive.

Key value for chemical safety assessment

Explosiveness:
non explosive

Additional information

Justification for classification or non-classification

Basing on the negative results of the 3 reliable tests the test item is not classified for explosive properties, according to EU GHS (CLP) criteria.
