−
for easily combustible materials of combustibility grade E (F), which quickly burn and burn themselves
even after removal of ignition source (such as paper, cardboard, asphalt and tar paper, wood and
wood-fiber boards, plastics, floor coverings) the safe distance has to be doubled, i.e. to 400 mm;
−
safe distance should be doubled as bulb where the grade of reaction to fire has not been proved.
