The rationale for the revision was to correct bracket placement on the equations and to make the standard more generic. The standard was probably written prior to the 1980s. Since that time, advances have been made in diffractometer design and detector technology. By changing the standard to specify diffractometer components required for a proper measurement instead of calling out a specific type of older equipment, then the standard should apply to anyone that uses good laboratory practice.
