15 Abnormal conditions The ballast shall not impair safety when operated under abnormal conditions at the maximum value of the rated voltage range. Abnormal conditions are working conditions in which one or more of the following apply: a) the lamp or one of the lamps is not inserted; b) the lamp does not start because one of the cathodes is broken; c) the lamp does not start although the cathode circuits are intact (deactivated lamp); d) the lamp operates, but one of the cathodes is deactivated or broken (rectifying effect). Compliance is checked by the following test. Each of the abnormal conditions specified above shall be applied with the ballast operating according to the manufacturer’s instructions (including heatsinks, if specified) for 1 h at the maximum limit of the temperature range for which the ballast is designed.
