That's the unfortunate part of the new technology end. Someone has to blaze the 'listing/labeling' trail by paying for a standard to be developed to have their product tested against. Then after a few years, other companies reverse engineer it and begin to offer similar products.
They too need a standard to test against because their product is just a bit different and likely wouldn't pass the protocols developed originally for the 'trailblazer.' So, they might get their own standard. Then, after a bit of time goes by, those standards are deemed obsolete and a new "harmonized" standard is needed so that these similar products are evaluated against the same protocols to level the field. So everything gets "delisted" and the manufacturers have to go through the listing process all over again.

I didn't know you could pay them to develop a standard though, I learn something every day here. TD GRS George, Mike's answer reminded me greatly of the first discussion I had with someone on the cost of a listed expansion chamber, which I thought was off the scale for what it actually consisted of. The client on that project still glares at me when we meet, because he thought I was padding the cost of the tank, as it was so high. -- PARSLEY CONSULTING Ken Wagoner, SET George Church wrote: > Not perceived as advertising here, Mike- > nice clear and concise explanation of all the tedious and expensive steps > required to develop new products. > > There are many who look at the raw manufacturing cost of a device without > considering the development costs divided into the # units expected to be > produced. > There are propriatory sprinkler devices that have similar "baggage" and the > market then determines whether the risk taken pays off in revenue sufficient > to cover the investment. > > >From your narrative, it's a steep slop to climb, eh?
