本报告总结了高压钠放电灯光通量测量的国际比对结果。来自九个不同国家的十三个实验室参加了这次比对，其中包括灯具制造商和国家标准实验室。鉴于此类灯具辐射的复杂光谱功率分布，内部比对结果显示照明应用的一致性达到了可接受的水平，13名参与者中有9人报告的结果在平均水平的±2%范围内。报告用英文写成，并附有法文和德文的简短摘要。共7页，1图1表。

This report summarizes the results of an international intercomparison of measurements of the luminous flux of high-pressure sodium discharge lamps. Thirteen laboratories from nine different countries took part in the intercomparison, both lamp manufacturers and national standards laboratories being represented. In view of the complex spectral power distribution of the radiation from this type of lamp, the results of intercomparison show an acceptable level of agreement for lighting applications, nine of the thirteen participants reporting results within ± 2% of the mean level.The Report is written in English, with a short summary in French and German. It consists of 7 pages with 1 figure and 1 table.
