This is what I posted today in the Buzz area, a user was asking what safety specs to look for:
"Unfortunately there really isn't any kind of pv-level standard, it is all ad-hoc, up to the individual.
The things that rolygate has been posting at the top level of ecf, recommendations to be careful on
batteries, look for things that talk about having current and/or temperature cutouts at the pv level, look for venting, are ecf's own attempts to start coming up with things to look for. I certainly don't agree with everything posted, and I really believe that ignoring single big battery units is sticking one's head in the sand (the very recent report of an 18650 battery entering a thermal runaway, though an alert user tossed it before anything bad happened, sounds real to me), but I also believe they are at least trying to come up with something, given nobody else has.
A single large 18650 has twice the total energy of anything in a notcigs pv, and the total energy is a major part of the potential for harm.
I actually am an engineer, can afford to buy whatever I want, and I honestly believe the current notcigs products are the best stuff out now. The new bp ii and lightning are the first pv to incorporate the new ecf-directed super slots, but I am entirely content with my existing bp, and original infinity (i did retrofit the infinity with the ipro delrin end cap, months ago). The big slots on the notcigs products buy even more safety margin, but the base product already has multiple safety features, is well thought out.
(Truthfully, if it was me I wouldn't have asked for the super slots, there are several viable approaches, including the delrin blowout plug, as long as the tube can accommodate rational battery swelling - notcigs pv do have oversized tubes.)
Sorry for the long-winded response, but it is a good quetion. A friend, justifiably spooked by recent things, asked for a good option for his wife. A notcigs PV was an easy, appropriate, answer
Update: I'm not certain, but notcigs may not be able to respond to you here. Vendors can't post in many areas (understandably). You can always post things where you want them to respond in the notcigs area of ecf suppliers. Buzzkill is pretty open about things, it is an forum."
The poster had run across one of the bogus pr stories, this one had mumbo jumbo assertions about how their products were safety tested. The big Chinese
eliquid manufacturers have sgs do a chemical test to make sure things aren't totally whacked, and the battery makers have to comply with RoHS and the UN38 standard that allows
batteries to be shipped by air; of course these things mean nada relative to pv-level safety, but they sound good
