Covers / shades and similar parts, which cannot withstand the 650°C glow wire test, shall be adequately spaced from any heated part that could raise the material to its ignition temperature. Generally the temperature of the lamp or the ballast / transformer will not rise the material to its ignition temperature, because the maximum temperature of the outside of a (compact) fluorescent lamp or small incandescent lamp is simply too low to do so. Besides there is a difference between the flash-ignition temperature of8 f! j' h; F+ l9 j& M
materials. Practical example is a lighting chain with plastic decorative cover, spaced about 15 mm from the lamp. The maximum temperature on the outside of the lamp (measured during the bridging test) was 180°C and the ignition temperature of the relevant material is much more than 180°C.

As the ignition temperature is not known over the life time, the ignition temperature of the relevant material shall not be considered.$ D \/ Z; ?0 `" r6 |! T5 l" J
