IPC-A-49 contains a test protocol for surface mount lead shear/pull. 
Because the test is contained in a round robin report (as opposed to a 
standard) I don't know that it can be considered an industry standard, 
but I suspect it is valid nonetheless. 

Send me a private e-mail with your Fax no. and I will be happy to send it 
to you.
