IEC TR 63158:2018（E）描述了一种客观频闪效应能见度（SVM）计，可应用于不同操作条件下照明设备的性能测试。 本文件中考虑的频闪效应仅限于人类观察者对一般室内应用中照明设备的时间光调制的可见频闪效应的客观评估，具有典型的室内光水平（>100 lx）和观察者或附近处理的物体的适度移动（<4 m/s）。条款A.1中给出了频闪效应能见度测量适用性限制的详细信息。

IEC TR 63158:2018(E) describes an objective stroboscopic effect visibility (SVM) meter, which can be applied for performance testing of lighting equipment under different operational conditions.
The stroboscopic effects considered in this document are limited to the objective assessment by a human observer of visible stroboscopic effects of temporal light modulation of lighting equipment in general indoor applications, with typical indoor light levels (> 100 lx) and with moderate movements of an observer or nearby handled object (< 4 m/s). Details on restriction of the applicability of the stroboscopic effect visibility measure is given in Clause A.1.
