No, he was correct. Long term exposure to the EU think tank will cause
you to grow an extra digit on your hand.

I may be mistaken, but I was under the impression that penta was 5 (as
in pentagon, a five sided shape).

Hi Camille, OrganicChemistry-UnChallenged IPC LF Listservers,
This is from a note by Camille, and I was wondering about a small point
that probably I should know.
<====
<I'll admit that when I first started reading about the RoHS and other
"green" technology issues a couple of years ago, I would sometimes call
something "halogen-free" rather than type out "does not contain the PBBs
or PBDE's, specifically penta-BDE and octa-BDE [because deca-BDE is
still okay, so even saying all poly-BDEs isn't technically correct] that
are banned by RoHS". The discussion early last year showed me that when
I was asking "halogens", I was using a far more generic term than I
realized.> <=====
penta is 06 I believe
octa is 08
deca is 10
If the above is correct what makes deca so much more stable.
Yours in Engineering, Dave
