I have no idea, the Kodak and GAF reps visited most of the AF photo labs and we were all told 10 years, I also seem to recall a technical order update that gave the same time line. I know that Kodak does lab work in which products are artifically aged, but I dont know the details, maybe PE does. I left the photo lab shortly after that, but most of the newspapers and wire services were also moving towards RC, for the same reasons they moved to digital. By the early 80 RC had really improved. I still like FB graded better than RC, but I am not too concerned about archival properties.
