Covers, shades and similar parts not having an insulation function and which do not
withstand the 650 °C glow-wire test of 13.3.2 shall be adequately spaced from any heated part
of the luminaire which could raise the material to its ignition temperature. These parts made of
flammable material shall have suitable fastenings or supporting devices to maintain this spacing.
The spacing from heated parts mentioned above shall be at least 30 mm, unless the material is
protected by a screen spaced at least 3 mm from the heated parts. This screen shall comply
with the needle-flame test of 13.3.1, shall have no holes, and shall have a height and a length
at least equal to the corresponding dimensions of the heated parts. A screen is not required in
cases where the luminaire provides an effective barrier to burning drops
