Thanks Werner,

I use the dogbones for just the reason you describe - process
management/control. There are a few cause and effect relationships in
plating chemistry that allow defect correction and preventiion. The dogbones
help with this just as do hull cell testing and simple things like auditing
plating baths with simple instruments like eyeballs and thermometers, as
examples.

My question is, besides that discussed in 484, what is the best method for
determining ductility. Does the hydraulic bulge tester provide a good
method? Is it part of 484 as I don't have access to the document or a tester
except that offered by the gentleman in your state?

Earl
