I’ve been making LED Neon Flex signs and I’d love to eventually sell them on, but I’ve started looking into CE testing/LVD and it’s looking like a minefield. Wondered if anyone knows the best way to go about it - It looks like you can self certify LVD/CE but there’s also companies offering it online - but would personalised signs need testing again? Seems like it’d get quite expensive! Also, if it’s built with plug and play components would it need testing at all?

Sorry if my question’s a bit muddled - I guess I’m wondering if there’s a guide for dummies, or if anyone has been through it and has any advice. Thanks in advance!

    \$\begingroup\$ Where does the neon come into the design? You also need to cover the EMC directive if you are CE marking - this is more problematic than LVD. Polarized comparison: LVD requires no testing; EMC requires thousands of $ to test. Think about the bigger issues here but, you may still not need to do EMC testing. It all depends on how your design pans out. \$\endgroup\$ – Andy aka Apr 22 at 17:53
  • \$\begingroup\$ There are testing houses that will do this for you. Figure about $5,000 USD. Whether or not you need it depends on your tolerance for risk. I.e. if something goes wrong, and somebody gets hurt, you might get sued. Or, if your RF emissions are beyond acceptable levels, the governments can shut you down and fine you. Plenty of cr*p is available on Amazon that has no UL or CE marking however, but those are kinda "untouchable" people. Even if something goes wrong, good luck tracking them down and getting compensated. You're easier to find. Just some musing.. I'm not a lawyer! \$\endgroup\$ – Kyle B Apr 22 at 17:58

  • \$\begingroup\$ @Andyaka The big one is actually environmental testing, to ensure that the product can't catch fire etc (EN 60950 & friends). If you ask a test house about environmental testing, they go completely bananas and suggest something far more expensive than EMC testing. I had one seriously suggest that I should test if my product was radioactive, which it has absolutely no reason to be. \$\endgroup\$ – Lundin Apr 23 at 6:43

    \$\begingroup\$ @Andyaka I’s neon flex that’s bent into letters and occasionally cut and joined back together (not soldered, just with a mid connection wire that the manufacturer sells, that are plugged into the flex), then it’s plugged into a 24v driver. I did read that as long as I included the 24v driver unplugged, I might be able to avoid the LVD side of things (but I’ve also read that if I’m selling the driver, even if it’s not connected, I’m still supposed to run my own tests). I didn’t know about the environmental bit either - I’ll do some more research on that! Thanks for your help :) \$\endgroup\$ – Letish Apr 23 at 9:45
