This International Standard specifies the safety and interchangeability requirements, together with the test methods and conditions required to show compliance of tubular fluorescent lamps with integrated means for controlling starting and stable operation (self-ballasted fluorescent lamps). These lamps are intended for domestic and similar general lighting purposes, having a rated voltage of 50V to 250V, having a rated frequency of 50Hz or 60Hz and having IEC60061‑1 compliant caps. For a cap-holder system not specifically mentioned in this standard, the relevant information on safety related tests provided by the manufacturer will apply. The requirements of this standard relate only to type testing. Recommendations for whole product testing or batch testing are given in AnnexA. This part of the standard covers photobiological safety according to IEC62471 and IECTR62471‑2 . Blue light and infrared hazards are below the level which requires marking.
