Re: [PSES] safety standards--outdoor electric machine

[Peter Tarver]

Hi, Chet.

I don’t know if you’re planning to use UL for as an NRTL, but I found the 
following.

I searched UL’s on-line certifications data base on the keyword conveyor. That 
led to several pages of certifications under a few product categories. The best 
match (in concept) was UL’s product category for Conveyors. Unfortunately, the 
UL Guide Card for this product category  explicitly states that it only covers 
equipment for use “within a building structure.“ While UL 73 does contain 
outdoor equipment requirements, this one product category that uses UL 73 
doesn’t allow certifications for outdoor use.

If you are planning to use UL, they can be convinced to create an outdoor 
conveyor category, since UL 73 does include outdoor equipment requirements. 
This process takes some time to accomplish and might not be completed before 
you’re ready to ship safety certified product.

Another option could be to use Outline of Investigation for Factory Automation 
Equipment, UL Subject 2011. Even though this Outline doesn’t explicitly include 
outdoor equipment requirements, it might fit the bill. (2011 does reference 
other standards that do have outdoor equipment requirements, so it’s a short 
leap to including the in the certification.) The product category for Factory 
Automation Equipment doesn’t limit the applications to indoor use. Subject 2011 
is used in conjunction with NFPA 79.

Peter Tarver

Hi, Doug—

Many thanks for the advice, and for the conveyor pub.  The guarding figures and 
accompanying rationale are really well done.  I’m quickly learning that 
conveyor systems in general are rather complex beasties concerning machinery 
safety!

Hi Chet,

I don’t have any opinion as to UL 73, as I am not familiar with that standard, 
sorry. I just wanted to be sure that the mechanical safety aspects were not 
forgotten.

There are some excellent ISO standards that you might also find useful, 
although they are aimed at a broader audience than “just” North America. Also, 
you might be interested in this conveyor safety guide produced by IRRST. 
Excellent stuff. English translation by the WSPS in Ontario, Canada.

[Chester Summers]

Hello, listmates-

I'm scoping North American electrical safety standards for an a.c. mains 
powered, portable conveyor system to support an outdoor construction process.  
Used to assist in handling pipe lining fabric at the jobsite.  The motor will 
likely be no greater than ¾ HP single phase, 120Vac/60Hz.  VFD motor speed 
controller to manage the short conveyor belt (approximately 6ft long).  There 
are no product specific standards for this type of equipment, however UL-73 for 
Motor Operated Appliances appears to check all the appropriate electrical 
safety boxes.  Conveyor-specific safety will be addressed with ASME B20.1.

I welcome expert opinions from the group-is UL-73 sufficient to evaluate this 
product?

Many thanks in advance,
Chet Summers
