What do the letters after the method number mean?

 

The letters following a method number (i.e., 3060A) refer to the number of revisions a method has undergone. The letter does not indicate a separate method. In the example above, Method 3060 and Method 3060A are the same method, but Method 3060A is an updated/revised version.
