Note:
If the value falls within the specified range, pro-
ceed to “Attaching the original mat} E-8”.

check for any deviation.
Deviation on the sample will be Y.
Deviation in + (plus) Deviation in - (minus)
(5) Obtain the difference between the deviation of
the chart and the deviation of the sample.
Difference of the deviation = Y - X
Specifications: 0 ± 2.0 mm
Note:
If the difference in deviations falls within the speci-
fied range, proceed to “Attaching the original mat}
E-8”.
If the difference in deviations does not fall within
