Dumb UL Question

[Jerramundi]

So, normally I strive to purchase products that are UL or ETL listed, or certified by another NRTL...

Normally I would simply look for a UL listed range hood, however, I've decided to familiarize myself with the actual UL listing associated with range hoods, which I understand to be UL 507.

Here's my question...

Would a range hood that is simply "UL listed" suffice, or would the marking have to explicitly state that it is "UL 507 listed?"

I've seen both UL markings that explicitly list the standard number and ones that don't, but this particular product seems to be difficult to locate.

I guess you could encounter the problem seen with some electrical appliances that have a UL Listed power cord and no other listing.

Not sure what you mean by that. Are you talking about a situation in which the power chord meets the UL standard for range hoods but the appliance does not? Is that even possible?

What I'm asking is....

UL 507 governs range hoods... so if a range hood is UL listed, does that mean it de facto satisfies 507?
Or is the hood explicitly required to bear a label stating that it satisfies, explicitly, UL 507?

UL does not require that the label show the standard number in it. It does require that the file number be there somewhere. You can do a search on line for the file number, which then tells you what standard it is listed to.

The time to get suspicious is when someone tells you it is listed, but the UL sticker is on only one COMPONENT of an appliance, ie the electric motor, but not on the appliance body itself. That’s what GoldDigger was alluding to, that some schlocky small appliance or tool suppliers will use a listed cord, trying to lead you to believe the entire appliance was listed.

Perhaps if it's being marketed as a chord that's another red flag?

Just sing to your hood and see if it's in tune

For real, though, I've seen lots of lighting that uses UL listed parts (or only one part), and they word in such a way as to make you think the whole thing is listed.

It wouldn't surprise me to see it on some appliances, too

As far as the mechanics are concerned, I'd rather find a part/appliance with the correct listing to avoid any potential issues.

I've dealt with that game since day #1 and have never been the type of guy to just grab whatever off the shelf at Home Depot. Unlike many of the people I know that would have you think the opposite while charging twice as much as I do.

The amount of stress I've endured to ensure the right part is used far surpasses what many ungrateful people deserve.

Music is just for me. It wakes up a man with a heavy heart.

Hopefully the UL label on the box the device comes in has a stronger meaning!
But, of course, no UL label has any value if there is not effective enforcement of its use.

I have a buddy that works over at UL. He said its not uncommon for people to send in a product to get UL listed as a whole, made up from individual UL listed products.
