Is agency approval requred for all equipt

Just wondering as I have seen/owned many items which are not stamped w/ agency approvals (UL / CE etc.). This includes electronics (amps / preamps / digital) and cables (power in particular). Seems like some of the "boutique" companies do not always have agency markings. And if the equipment is not agency reveiwed / approved, is this risky for the consumer. I also wonder what liability (if any) the manufacturer holds if a fire or problem would occur. Just wondering...

ALL devices say they cannot emit RFI, yet have to accept it, as far as i know. It is just one of those 'huh' things.
Government regulations.
Maybe the nukes carried around in B2s don't have to accept the RFI?? but everything else does.. (medical devices may also be exempt?)

I'll bet it costs a bundle to get a UL cert....or the equivalent from Canada or Europe.
That alone should preclude some small production / boutique brands from getting such.

I DO think it should be illegal to not serialize equipment thru a unique number.
The build sheet for a particular piece or batch will list sources of parts and such so if a defect is found ( HEY, those caps I sold you? no good!) gear can be tracked down and either fixed or replaced.

Hi Elizabeth, my post was in response to Sfstereo post that sounds like the CE stamp is better than can be had in the US without it. Maybe it the networking field, but I don't see it doing anything, that is advantageous for audio sound here. The post I'm referring to, is below.

Yes, CE is for Europe. FCC testing is required on digital devices but it only test for EMI emissions but CE requires additional immunity testing such as surge, RF immunity, transient, ESD and power factor correction. These were the requirements when I last did some CE testing many years ago.
