BS PD IEC/TR 63158:2018 describes an objective stroboscopic effect visibility (SVM) meter, which can beapplied for performance testing of lighting equipment under different operational conditions.The stroboscopic effects considered in this document are limited to the objective assessmentby a human observer of visible stroboscopic effects of temporal light modulation of lightingequipment in general indoor applications, with typical indoor light levels (> 100 lx) and withmoderate movements of an observer or nearby handled object (< 4 m/s). Details on restrictionof the applicability of the stroboscopic effect visibility measure is given in Clause A.1.For assessing unwanted stroboscopic effects in other applications, such as the misperceptionof rapidly rotating or moving machinery in an industrial environment for example, othermetrics and methods can be required.The object of this document is to establish a common and objective reference for evaluatingthe performance of lighting equipment in terms of stroboscopic effect. Temporal changes inthe colour of the light (chromatic effects) are not considered in this test. This documentdescribes the methodology for SVM and does not define any limits.The objective method and procedure described in this document are based onCIE TN 006:2016 on temporal light artefacts (TLAs).The method described in this document can be applied to objectively assess the stroboscopiceffect of lighting equipment that is powered from any type of source, AC mains, DC mains,battery fed or fed through an external dimmer.Cross References:IEC TR 63037:2016IEC/TR 61547-1:2017ISO 11664-1:2007IEC 61547:2009/ISH1:2013IEC 61547:2009IEC TR 63036:2016NEMA SSL 7A:2015IEEE 1789:2015CIE TN 006:2016JCGM 100:2008CIE S 014-1/E:2006CIE S 025:2015
