That's absurd. How did they not run afoul of false advertising laws? (Oh, that federalregister.gov link says "The RLDWA revised the definition of lead free.")

That's absurd. How did they not run afoul of false advertising laws? (Oh, that federalregister.gov link says "The RLDWA revised the definition of lead free.") My layperson expectations: • "low-X": < 1/3 is X. • "trace amounts of X": <1% is X. • "X-free": no reasonably detectable amount is X. Obviously there's some wiggle room for how sensitive the detectors are, but it should be less that "trace amounts," i.e. 0%. This reminds me of "waterproof" which generally just means it can survive being splashed or rained on for a few minutes, but not submerged.
