Linearity - Minimum and maximum value for acceptance of the equipment?

[Luis Alves]

Hi all
After a small discussion in the MSA Forum, some doubts occur which are related to this forum and as suggested my Mark I put the two questions here.
First what is the minimum and maximum value for acceptance of the equipment?
Second what should be the process variation of a measuring range of 1 to 150 mm? 74,5 is a good value?
Tanks in advance,

A second question is:

In MSA manual an example of a linearity studie is present. My question is when they calculate the linearity they they use 6.00 for process variation. Where they find that value?
