Sample preparation for measurement of mercury level in fluorescent lamps (IEC 62554:2011 + A1:2017) (english version)
This International Standard specifies sample preparation methods for determining mercury
levels in new tubular fluorescent lamps (including single capped, double capped, self-ballasted
and CCFL for backlighting) containing 0,1 mg mercury or more. The intended resolution of the
methods described in this standard is of the order of 5 %.
Mercury level measurement of spent lamps is excluded, as during lamp operation, mercury
gradually diffuses into the glass wall and reacts with the glass materials. The test method of this
standard does not recover mercury that is diffused into or reacted with or otherwise incorporated
irreversibly with the glass wall of discharge tubes.
This standard does not contain information on measurement. Measurement is specified in
IEC 62321.
