Decoding the Inscrutable Logos On Your Electronics
jfruhlinger writes "If you've bought a piece of electronic equipment — a computer, a printer, even a lowly power supply — you've no doubt noticed a host of inscrutable logos festooned all over it — UL, CE, FCC, TUV, RoHS, ENERGY STAR, and the like. What do they mean? Each of these compliance marks tell a story about your gadget's operation or lifecycle, and knowing what they mean can let you in on the hidden life of the gizmos you buy."
No, tuffer than that.
Dielectric strength is tested; mains separation from consumer touchable parts are tested; holes can't be big enough to stick a small screwdriver or knife into (something that conducts more than .25") into the chassis, and so on. Yes, electrical safety, but beyond first article inspection, there's a long list of details to keep an object "safe" for consumers so that liability can be reduced, and insurance costs go down.

That only applies if you're going for an Ingress Protection rating.

Still waiting on Serviscope_minor to wake up to fucking reality and realize that Jessica Price isn't going to fuck him.
