Decision: In principle apply the requirements given in IEC/EN 60825-1. However in order
to avoid expensive measurements, the luminaires provided with LEDs should be

IEC/EN 60825-1 and consequently there is no need measurements. During the

  _( z, Z- S# Z, b5 }4 b- In all other cases the luminaire manufacturer shall be asked to provide a declaration

- If such a declaration cannot be provided or if we are insecure on how to judge, the
measurements given in IEC/EN 60825-1 shall be performed. In the TRF it is indicated
that measurements have been performed. For luminaires containing light sources
