So Yellow CSST is STILL approved, don't need to use only the black.

Yes its approved and still manufactured by the train load. But its got a serious problem that I believe will eventually lead to it being recalled. What does it tell you when the folks who manufacture it come out with a new version (black) and advertise it as "400 times more lightning resistant that yellow CSST." Oh and the name of the black stuff is "counterstrike" A nice little reference to the failure problem of the yellow stuff. I sure as hell would not have yellow CSST in my home.

I agree it is not the best product for the untrained installer.
Seeing the pdf file posted above would seem to indicate a installation shortcoming of yellow installations not being grounded satisfactorily as being the lightning hazard. And likely due to unqualified or untrained installers being able to easily purchase and then install it without attaching the required grounding.
So then, I guess, the Black version is idiot-proof if/when installed w/o compliant grounding being in place, but at a higher cost no less.
Even satellite and cable TV providers have grounding requirements at or before point of entry from outside of the home.
Saving the TV tuner box is more important that saving the house from exploding as for lightning hazards.

Technically its bonding, not grounding. The black CSST doesn't require any bonding. The yellow stuff does and still may fail in a lightning strike no matter how well installed. Below is a statement required by Maryland law in my reports if the home I'm inspecting has yellow CSST. Doesn't instill lots of confidence. "Manufacturers believe."
“Manufacturers believe that yellow corrugated stainless steel tubing (CSST) is safer if properly bonded as required by the manufacturer’s installation instructions. Proper bonding of CSST can be determined only by a licensed master electrician.”

Yep, Manufacturer says that all in above referenced pdf, so makes sense to enforce mfg'r installation instructions.
However, it may be a stretch of facts that properly bonded and grounded yellow could lightning fail, don't you think?

I’m not convinced that properly installed and bonded yellow CSST will not fail in a lightning strike. I read once that a typical lightning bolt is considered to be about 100 million volts. I’m skeptical of the effectiveness of #6 copper under that condition. Black iron can carry a load to ground. CSST will arc.
Yes there are probably millions of homes with CSST and the failure rate is very small. I chalk that up more to the likelihood of a home to be struck by lightning. Not the ability of this material to withstand it.
