CAS number: 123-76-2
The flammability of the test item was
evaluated according to the EU Method A.10 and UN Method N.1.
The test item was formed into an unbroken
strip or powder train about 250 mm long and a preliminary screening test
performed to determine if, on ignition by a gas flame, propagation by
burning with flame or smouldering occurs.
In the safety pre-test following the EU
method A10, the test item started to melt und burned with a yellow
flame. In the preliminary screening test the test item melted into a
colourless liquid. No indications of flammability could be observed.
Therefore, the test item should not be
considered as highly flammable (for EU regulations) and not classified
as a flammable solid (for UN regulations).
According to the CLP Regulation (EC) No.
1272/2008: A flammable solid means a solid which is readily combustible,
or may cause or contribute to fire through friction. Readily combustible
solids are powdered, granular, or pasty substances or mixtures which are
dangerous if they can be easily ignited by brief contact with an
ignition source, such as a burning match, and if the flame spreads
rapidly. The classification criteria for flammable solids are indicated
in the CLP Regulation as follows:
Annex I: 18.104.22.168. Powdered, granular or
pasty substances or mixtures (except powders of metals or metal alloys –
see 22.214.171.124) shall be classified as readily combustible solids when the
time of burning of one or more of the test runs, performed in accordance
with the test method described in Part III, sub-section 33.2.1, of the
UN RTDG, Manual of Tests and Criteria, is less than 45 seconds or the
rate of burning is more than 2,2 mm/s. 126.96.36.199. Powders of metals or
metal alloys shall be classified as flammable solids when they can be
ignited and the reaction spreads over the whole length of the sample in
10 minutes or less. 188.8.131.52. A flammable solid shall be classified in
one of the two categories for this class using Method N.1 as described
in 33.2.1 of the UN RTDG, Manual of Tests and Criteria in accordance
with Table 2.7.1;
During the preliminary test the substance melted
into a colourless liquid. No indications of flammability could be
ob-served. No burning rate was therefore determined and the substance is
not classified as flammable according to the CLP Regulation (EC)
