lead lead everywhere

California has a new law that specifies limits
for lead in jewelry products. Even though the answer to my question should be a no-brainer, I need to confirm:

In the text of the law
, specifically section 3.2.2, it says that "Class 2" plated metals should be made of metal alloys that contain less than 10% lead by weight ("88 metal").
Then later in section 188.8.131.52 it talks about plastic or rubber materials needing to contain less than 0.06% (600 parts per million) lead.
Does that mean the 10% translates to 600,000 parts per million lead?
That is, if 0.06% = 600 PPM, then 10% should = 600,000 PPM. Correct? It just seems like a huge difference.
