Any other information on results incl. tables

Mechanical sensitivity (friction)

The test item was sieved (mesh size 0.5 mm) before the measurement. No explosion occurred within 6 tests using a pinload of 360 N, only a discoloration of the test item was observed in all tests.

Mechanical Sensitivity (shock)

The test item was sieved (mesh size 0.5 mm) before the measurement. No explosion within 6 tests using a mass of 10 kg falling from a height of 0.4 m was observed, only a discoloration of the test item was observed in all tests.

Thermal sensitivity

Three tests were performed with a circular nozzle plate with a hole of 2 mm diameter. No explosion was observed. Table 1 gives the results of the thermal sensitivity.

The test on thermal sensitivity carried out with a nozzle with a diameter of 2.0 mm showed no explosion. Compared to the nozzle with a diameter of 6.0 mm the venting area of the nozzle with 2.0 mm is smaller by an order of magnitude. Additionally the physical state of the test item excludes the enrichment of high-energy components caused by evaporation of volatile solvents. Due to these facts an explosion with a nozzle width of 6.0 mm was excluded.

Applicant's summary and conclusion

Interpretation of results:
non explosive
Remarks:
Migrated information
Conclusions:
The test item had no explosive properties according to Regulation(EC) No. 440/2008, Method A.14. and therefore has not to be classified as explosive according to Regulation (EC) No 1272/2008.
