Hi John,
Within the family of IPC Electronic Manufacturing documents, IPC-A-610D (D is current revision) defines acceptability where the processes and materials are defined in J-STD-001D (current revision). 610 also contains a slightly broader scope than 001 which is focused upon soldering specifically. They work well when used together and the definitions are consistent for the Class prescribed. 

Best regards, 
Mel

I am not sure if this is the right forum for this question.

We may have a requirement to assemble to class 3.

I have a copy of ipc-a-610 and my impression is that this is more of inspect
to class 3 kind of thing. Does class 3 assembly have requirements for
fluxes, solders etc etc

Any input will be greatly appreciated.

Thank You
John Foster
