Product Usage
Product usage introduction
Tolerances on standoff values
a) Standoff of the Working ring gauge to the product pin: S2 +0.25/−0.13 mm (S 2 +0.010/−0.005 in.).
b) Standoff of the Working plug gauge to the product box: (S − S 1) + 0.25/0 mm [(S − S 1) +0.010/0 in.].

Description of product use effect
The standoff value, S0, of certified Reference Master gauges is
the distance from the plane of the rotary shoulder on the plug gauge to the plane of the gauge point on the
ring gauge. The certified Reference Master ring gauge is used to establish the standoff value, S1, of the
Working plug gauge. The certified Reference Master plug gauge is used to establish the standoff value, S2,
of the Working ring gauge. S1 and S2 are measured values that the Working gauges stand off from their
certified Reference Master gauges and may be greater or less than S
