标准摘要
[中文适用范围]： IEC 62554:2011+AMD1:2017+AMD2:2025 CSV 规定了用于测定新型管状荧光灯（包括单端、双端、自镇流和用于背光的 CCFL）中汞含量的样品制备方法，这些灯中汞含量为 0.1 mg 或更多。本标准中所述方法的预期分辨率为 5% 的数量级。不包括废旧灯的汞含量测量，因为在灯工作期间，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会回收扩散到放电管玻璃壁中或与之发生反应或以其他方式不可逆地结合的汞。本标准不包含有关测量的信息。测量在 IEC 62321 中指定。 [外文原描述]： IEC 62554:2011+AMD1:2017+AMD2:2025 CSV 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.
