Atex Marking
Atex Marking
(OP)
Can someone tell me what the difference between EEx and Ex is in the following context:
II 2 G EEx de IIC or II 2 G Ex de IIC
Have seen products that carry both marks. I know EEx says the product complies with European standards, but wouldn't all Atex equipment comply with Euro. standards? I am confused, please help.
Thanks.

RE: Atex Marking
The Ex markings that you have listed would be interpreted as applying to a piece of equipment that is marked as explosion protected using the marking system from the zone system of area classification. This could be used in North America or for any product under the IECEx scheme. The additional E in EEx however implies the use of a CENELEC standard and should be used on a product that is ATEX approved.
Are you sure that the Ex mark is on an ATEX approved piece of equipment?

RE: Atex Marking
Is there an EN standard that covers atex marking? I have the directive and applicable product standards. There seems to be little information contained in them as to how to mark the product.
