Requirements for Repair of Hazardous Area Equipment

Requirements for Repair of Hazardous Area Equipment

Requirements for Repair of Hazardous Area Equipment

(OP)
We produce an industrial product that has been certified by UL for Class I Div II in North America and UL/Demko for Class I Zone 2 European hazardous locations. I am trying to determine if UL has a document or standard that governs the requirements for repair/refurbishment of Class 1 Div II equipment.

IEC has 60079-19 which relates repair of "European" Zone clasified hazardous area equipment. FM has FM3606 which relates to FM approved hazardous area equipment. I haven't been able to find a UL equivalent to these two standards for North American hazardous area equipment.

I also looked through the NEC (2005 Edition) and didn't see anything pertaining to repairs of quipment.

Any info would be appriciated.

RE: Requirements for Repair of Hazardous Area Equipment

FWIW, I believe FM is fairly widely accepted in North America too.   

2008_WhiteBook.pdf from UL might get you started on your search; I don't remember where I downloaded it from, but Google should find it.  

Hopefully you'll find something more insightful than this on p. 44:  

"The continued acceptability of the equipment will depend upon proper maintenance."

FM is definitely accepted in the US.  They're located in the US.

You can read the scope of UL 1604, Standard for Electrical Equipment For Use In Class I and II, Division 2, And Class III Hazardous (Classified) Locations
