Definition
The tolerance zone is limited in the
measuring plane by two straight lines
a distance
t apart and parallel to the
datum.
What is to be contained within
the tolerance zone is not the entire
profile that has been assessed but that
portion of the LSLI line computed for
the entered measuring length.
conicity
Example
Each portion of the LSLI line
calculated for the entered measuring
length on the toleranced generating
line shall be contained between two
straight lines 0.04 apart and parallel to
the opposite generating line.
Note
The parallelism deviation may be
larger; if necessary, it can be
toleranced separately.
