Test material

Constituent 1
Reference substance name:
BIBR 1048 Oxa-Ester
IUPAC Name:
BIBR 1048 Oxa-Ester
Test material form:
solid: particulate/powder
Remarks:
migrated information: powder
Details on test material:
The test was conducted with a test substance with a residual water content of 0.14 %. For the test only the fraction with particle sizes < 63 µm was used.

Results and discussion

Results:
The minimum ignition energy of the test substance (residual water content 0.14 %) was determined to 2.6 mJ at 22°C and a rel. hunmidity of 43 %.
Therefore the dust of the test substance can be classified as extremely combustible.
Even the equivalent energy of electrostatically induced brush discharges (eg. discharge of PE bags) may be sufficient to cause a dust explosion.
Moreover, sparks and propagating brush discharges can lead to a dust explosion of the test substance.
