Hi.
tell me what this code means:
eexd iib t4
I don't understand the atex zone that covers.
Thank you.

I'm trying to answer you. .the code you have indicated represents the information contained in the additional marking required for atex products, but alone it is not enough to define where that product can be used as you need the part before the code (e.g. 1g, 2g, etc.). ..certainly your product is electrical and can be used in atex environments related to the presence of gas. the info you specified are characteristics of electrical products and in particular:
1) iib is a reference to the type of substance for the modes of protection "d", the group ii is divided into iia, iib, iic (depending on the infimmability of the substance). In particular, the iib group means that it is a device that should not be used in mines (group i) and must be used in the presence of ethylene gases (group b representative).
iib group equipment can be used in places requiring iia group construction but not in places requiring iic group (e.g. in the presence of gas like hydrogen)
2) t4 is the temperature class and indicates that no part of the equipment has a t > 135°c and therefore can be used exclusively with substances whose flammability temperature is greater than 135°c.
I hope I've been clear.
greetings

hi, can you report or link a table that can decrypt the various atex codes, from the most banal to the most complex? :wink:I'll try and answer you. . .
I hope I've been clear.
