IEC 62554:2011+A1:2017规定了测定含汞0.1 mg或以上的新型管式荧光灯（包括单盖、双盖、自镇流和背光用CCFL）中汞含量的样品制备方法。本标准中描述的方法的预期分离度约为5%。废旧灯的汞含量测量被排除在外，因为在灯运行期间，汞会逐渐扩散到玻璃壁中并与玻璃材料发生反应。本标准的测试方法不回收扩散到放电管玻璃壁中或与放电管玻璃壁发生反应或以其他方式不可逆地结合在放电管玻璃壁中的汞。本标准不包含有关测量的信息。IEC 62321中规定了测量。该合并版本由第一版（2011年）及其修正案1（2017年）组成。因此，除本出版物外，无需下令修订。

IEC 62554:2011+A1:2017 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. This consolidated version consists of the first edition (2011) and its amendment 1 (2017). Therefore, no need to order amendment in addition to this publication.
