The accumulation of mill tolerances and fabrication tolerances shall not cause the erection tolerances to be exceeded.
Commentary
In editions of this Code previous to the 2005 edition, it was stated that “…variations are deemed to be within the limits of good practice when they do not exceed the cumulative effect of rolling tolerances, fabricating tolerances and erection tolerances.” It is recognized in the current provision in this Section that accumulations of mill tolerances and fabrication tolerances generally occur between the locations at which erection tolerances are applied, and not at the same locations.
