If visual examination of a light appears to reveal substantial local variations of intensity, a check shall be made to ensure that, outside the axes, no intensity measured within the rhombus defined by the extreme directions of measurement is below 75 cd (see diagram below).
Kui valguse visuaalsel vaatlusel selgub, et valgustugevus erineb paiguti oluliselt, tuleb kontrollida, et valgustugevus ei langeks telgedest väljaspool rombis, mille moodustavad mõõtmispiirid, kusagil alla 75 cd (vt diagramm allpool).
