The cspnet article reads like a variant of the press release put out weeks back by Kiklas and TVECA. Suppositions spoken as if facts. ecigarettesjunction is a "review" site that appears to be a fake site, with obviously junk "reviews", links that don't work, etc. The "most popular" e-cigarettes are from the ones we warn people about (I know because my first PV was one of the brands, and when you read the "reviews" they are totally PR)
The last paragraph, talking about SGS certification was a complete shrug to me. I actually am a techie, an engineer, did a "... are they saying?" when I read it.
SGS is a real testing company, qualified to perform certifications to various standards (e.g., they can generate proper tests, obtain UL listings). At best, maybe it was some kind of way to assert, in this PR puff piece, "our proprietary, over-priced, PV, must be good because at least in theory we could pay to have SGS test it, if only there was some standard for SGS to test it to".
(PRish stuff comes out poised as real journalism, trying to sift through things isn't easy.)
