.1%, not .01%.
  .01% is for Cadmium...
  Just splitting a few hairs.
  Obviously you haven't become completely numb to the idiocy yet.  You are reacting like you are surprised that this legislation isn't realistic.

.01%. Therefore if even a single pad that did not have 100% of the old
63/37 solder stripped off is tested at the assembly level, and fails at
Pb=.0100000000001%, the whole lot of that particular assembly or product
is non-compliant and the RoHS Police will throw you in the basement of
the jail, rape your wife, sell your children into slavery and close up
your business or sell it to your nearest competitor.

For the sake of facilitating recycling?

Isn't that rather unrealistic also?

Richard,
My understanding for the reason for this definition is to close
loopholes.
If the amount of Pb was based on the total product weight, people may
just pad the product weight in other ways to allow more Pb usage.
It is unrealistic to expect someone to test an entire assembly to the
complete homogeneous level on a regular basis, but it allows them to
prosecute based on any one high Pb concentration area they may find.

Regards.
