testing method:
9 z: f( a( ^6 t2 p# c9 \6 j G13.2 the lamp is switched on at ambinent temperature (definition as in IEC/TS 62504 and conditions as indicated by the manufacturer or the power is increased until 150%of the rated power is reached.
. D& T7 O, u' ^' O; j; J y; Ythe test is continued until the lamp is thermally stabilised. a stable condition is reached, if the lamp cap temperature does not change by more than 1k in 1h the lamp shall withstand the extreme electrical conditions for at least 15min , after stabilization is reached.0 V* Y8 j; N$ W
a lamp which fails safe and has withstood the extreme electrical conditions for 15min ,has passed the test, provideed the compliance(see 4.1 and 13.6) is fulfilled.
