The test on dust explosion of Vulkanox
delivered the following result: The lower dust explosion limit for this
substance is determined to be 10 g/m³, the ignition temperature for the
dust is 330 °C, the explosion pressure maximum pmax is 9.2 bar.
The lower dust explosion limit of Vulkanox
is determined to be 10 g/m³ according to test method DIN EN 14034. The
dust explosion test gives evidence that only the dust of Vulkanox has
explosive potential und specific conditions - i. e. vapourised dust in a
closed system with an ignition source - but not the solid substance
itself under normal conditions.
Waiving of study:
Two studies - one carried out by Currenta (Klein, Blank, 2008) and one
at BIA (1993) - on the dust explosion of DBMC show that only the dust of
this substance has explosive properties, whereas the solid form, which
is the commercial form, has no such properties. Thus, DBMC is not
regarded as explosive which is in accordance with the molecular
structure of this substance which does not possess any chemical group
associated with explosive properties.
Based on the structure of the molecule and
taking into account the provisions laid down in Council Directive
67/548/EEC and Guidance to Regulation (EC) No 1272/2008, DBMC does not
have to be classified with respect to explosive properties.
