Ah, if only it were possible to be a fly-on-the-wall in every committee for every standard... I know this is a fantasy only a standards-geek could have, and is one of those fantasies you don't really want to actualize, but there's no doubt much of the real work defining the rules of the game is done in committee meetings that most of us never hear about.
In their last meeting, with little fanfare, the NSF-140 committee
approved a simple change that greenwash-fighters should approve of, while finding the need for it unfortunate.
The language in the standard was changed to say, "A certified and non-certified product cannot have the same trade name designation."
What this means is that a company can't get, for example, NSF-140 Platinum on select options
for a product line, and then go and market the main product line
as NSF-140 Platinum. Apparently, this issue was brought to the table because one company was doing just that — marketing the product line as NSF-140 Platinum despite the fact that the platinum prerequisite of 10% post-consumer recycled material was only met with special order options.
