Hello everyone,
I'm not sure this is the right section for this topic.
Anyway, do you know what "ex" means here?
(a) 15wt%, 10% Pb ex
(b) 15wt%, 10% Pb ex, 1% Mn
(c) 15wt%, 13% Pb ex, 1% Mn
It refers to a plot in a patent (https://patents.google.com/patent/EP3220431A1/en, you'll find it in the fourth image).
Thank you!

Have you tried actually reading the patent? (See sections 70 and 71.)

Yes, I have, but had not made the connection with that. Thank you!
