Silver nitrate test is to check for the presence of OSP only. 
 
 To check for thickness you need to process a standard coupon, dissolve the 
 OSP in an mild acid, and process solution sample in a UV 
 Spectraphotometer. Then convert the reading to thickness with a 
 correlation constant.
 
 Enthone OMI can provide you with all of the details.

     Can anyone tell me where to get Data on a "Silver Nitrate Test" to 
     check thickness on OSP's.
 
     Has anyone arrived on an acceptable thickness range on OSP's at this 
     time?
 
     Thanks in Advance for any response
