Reference radiographs, castings

Dear Colleagues,
This question referes to radiographs ASTM E155, E446, E186, E280, E689 and E272.
Does anyone know, whether there is any essential difference between the old versions (1980's and 90's) of these radiographs and the new versions (2004).
Thanks in advance.
Norman
