Mechanical sensitivity test (shock)

The test conditions were :

Atmospheric pressureof about 98.2 kPa

The test item was used as supplied.

Safety-in-handling test

A small quantity of the test item was submitted to a shock by means of a metallic device: No signs of explosion were recorded.

Main test

Six essays have been performed. The results are presented in the following table.

Heat sensitivity (flame)

Safety-in-handling test

A small quantity of the test item was submitted to a flame from a gas burner: The test item boiled and evaporated, no signs of explosion were recorded.

Main test

The test conditions were:

Gas rate of approximately 3.2 L/min

Volume of test item to reach 6-cm height in the test tube of about 29 mL

Observed reactions :

Assays using a tube with a hole of 6-mm diameter

Assay No. 1: From 2 minutes and 56 seconds to 4 minutes and 35 seconds, a 50-cm height yellow flame was observed. From 4 minutes 35 seconds to 4 minutes 42 seconds, a 1.25-m height yellow flame and projections were observed. From 4 minutes and 42 seconds to 5 minutes, a 75-cm height yellow flame was observed.

Assay No. 2: From 3 minutes and 12 seconds to 4 minutes and 22 seconds, a 50-cm height yellow flame was observed. From 4 minutes 22 seconds to 4 minutes 31 seconds, a 1.25-m height yellow flame and projections were observed. From 4 minutes and 31 seconds to 5 minutes, a 75-cm height yellow flame was observed.

Assay No. 3: From 3 minutes and 33 seconds to 4 minutes and 36 seconds, a 50-cm height yellow flame was observed. From 4 minutes 36 seconds to 4 minutes 52 seconds, a 1.25-m height yellow flame and projections were observed. From 4 minutes and 52 seconds to 5 minutes, a 75-cm height yellow flame was observed.

Assays using a tube with a hole of 2-mm diameter

Assay No. 4: From 3 minute 23 seconds to 4 minutes and 30 seconds, a 25-cm height yellow flame was observed. From 4 minutes and 30 seconds to 5 minutes, overpressure, projections and 100-cm height yellow flame were observed.

Assay No. 5: From 3 minute 27 seconds to 4 minutes and 20 seconds, a 25-cm height yellow flame was observed. From 4 minutes and 20 seconds to 5 minutes, overpressure, projections and 1-m height yellow flame were observed.

Assay No. 6: From 2 minute 55 seconds to 4 minutes and 21 seconds, the test item overflowed and a 25-cm height yellow flame was observed. From 4 minutes and 21 seconds to 5 minutes, overpressure, projections and 1-m height yellow flame were observed.

Conclusion

Six negative assays were recorded: No heat sensitivity was noted with the test item.

 

Applicant's summary and conclusion

Interpretation of results:
non explosive
Remarks:
Migrated information
Conclusions:
No mechanical sensitivity (shock test) was observed with the test item during the six assays. No heat sensitivity (flame test) was observed with the test item during the six assays.
The test item was not considered to have explosive properties in the experimental conditions used.
Executive summary:

The determination of the explosive properties was performed according to the Regulation (EC) n°440/2008, A.14: “EXPLOSIVE PROPERTIES”, May 2008.

The test item is considered as presenting a danger of explosion if:

- An explosion (the tube bursts into three or more fragments) occurs within the fixed number of tests for heat sensitivity or,

- An explosion (bursting into flame and/or a report equivalent to explosion) occurs at least once in six tests of mechanical sensitivity (shock). No mechanical sensitivity(shock test)was observed with the test item during thesix assays. No heat sensitivity(flame test)was observed with the test item during thesix assays.

The test item was not considered to have explosive properties in the experimental conditions used.
