not cause electrical shock, but it could open safety fuses or circuit breakers and cause fire. ... KEMET 900 Series Safety Disc Capacitors are offered with a combination ... KEMET 900 Series devices do not have UL or CSA certifications. It is not ( me-I tried to link this but had trouble for some reason. They state on page 10 that they are not UL or CSA certified and that they don't need to be. If you google 900 series capacitors not UL certified you will come up with this. Open and go to page 10.)

You have to be really careful with language when it comes to the lawyers, UL and all that. The parts in question are UL recognized, and are marked as such. You can be certain UL would not allow this to continue unless UL felt they were up to the task. UL has it's own really good lawyers to ensure this kind of thing and you can trust me when I say they aren't afraid to use them. I'm not sure what you mean when you state they aren't certified, as per data sheet they are recognized and presumably meet the minimum requirements to display that level of UL mark for that purpose.
The 900 series may not all be recognized parts but the ones with the mark almost certainly are!
I would guess that approval and certification mean the same thing. If you blow up the photo of the cap on the link I saw first and sent there is no UL approval printing on it. Usually one is on pretty solid ground when quoting direct from the horses mouth. So you can see that I didn't make it up. Something changed. I would still be happier and it looks like Kemet agrees, with a cap that is more likely to fail in a open than in a short. Rare events. Much happier with a "better quality cap" of larger value. Your mileage may vary. Are you not the least bit curious if my opinion along with the opinion of at least the person who wrote "The Great Capacitor Shootout" has any merit from a direct experience? To get the job done? Well Kemet thinks that much larger caps get some job done in relation to EMI filtering.Why would they make them otherwise? What job I'm talking about is improvement in subjective sound quality. I've tried weird tweaks with both amazement and other respected tweaks with no perception of improvement and even degradation. But I at least gave them a shot. Hey, digits are digits,right? T456

Recognized means that a component is not Listed as a stand-alone device to be used any which way an end-user might try, but if used as part of an assembly or larger device, and that device is Listed.
A common example is industrial control panels.
Interesting info. So now we have recognized, approved and certified. T456
