Apologies if this appears like a simple question. I have carried out a survey of a Zone 2 area and one piece of equipment, an enclosure, is fitted and only identifiable by manufacturers name plate and a stuck on EEx ia sticker. No Atex data plate. The previous survey (visual) gave some details of the enclosure but nothing on T rating or certification details.
Is the non Ex equipment suitable for the area with EEx ia equipment only inside?
