1.TOLERANCE (length)

RANGE	GENERAL	SPECIAL
0 ~ 10mm (0~3/8")	+/- 0.2mm (+/- .008")	+/- 0.1mm (+/- .004")
11 ~ 25mm (3/8"~1")	+/- 0.25mm (+/- .010")	+/- 0.13mm (+/- .005")
26 ~ 50mm (1"~2")	+/- 0.35mm (+/- .014")	+/- 0.20mm (+/- .008")
51 ~ 75mm (2"~3")	+/- 0.40mm (+/- .016")	+/- 0.25mm (+/- .010")
76 ~ 100mm (3"~4")	+/- 0.50mm (+/- .020")	+/- 0.30mm (+/- .012")
101 ~ (4"~)	+/- 0.70mm (+/- .028")	+/- 0.35mm (+/- .014")

2.ANGLE

SHAPE	GENERAL	SPECIAL
	+/- 2 degrees	+/- 0.1mm (+/- .004")
	+/- 1/2 degrees	+/- 0.13mm (+/- .005")
	+/- 1/2 degrees	+/- 0.20mm (+/- .008")

3.FLATNESS AND STRAIGHTNESS
- Same as the above, tolerance.

4.CONCENTRICITY
- Generally, concentricity is 0.13mm(0.005") T.I.R per 25.4mm(1") of the separation of an exterior and interior angle
When the length exceed two times of sepatation, the rate of straight line should be added to the concentricity

5.CIRCULARITY

DIAMETER	T.I.R(TOTAL INDICATOR READING)
0 ~ 10mm (0 ~ 3/8")	0.25mm (.010")
11 ~ 25mm (3/8" ~ 1")	0.35mm (.014")
26 ~ 50mm (1" ~ 2")	0.50mm (.020")
ON LARGER DIAMETER, DIMENSIONAL TOLERANCE SHOULD BE APPLIED
