$ I8 m: Y8 a. |6 rQuestion:
3 ~+ `7 q5 I5 J2 x/ ~2 ]+ m6 LClause 4.15 requires that covers, shades and similar parts not withstanding the 650°C glow wire test, shall be at a distance of 30 mm from the heated part. How should we define a heated part? Is a 3 W “candle looking” glimmer lamp considered to be a heated part? If no, can we decide a limit for incandescent lamps considered to be heated parts, e.g. more than 15 W?

Light sources, ballasts and transformers are regarded as heated parts.
