* The criteria for pass/fail judgment are different between the conventional JIS and the current JIS (ISO).

●Pass/fail judgment based on the current JIS (ISO)

PP GO (street): pull out through without difficulty (penetration)

PP NOT GO: Passes if neither side has more than one turn of the screw

●Conventional JIS pass/fail judgment

WM GO (Machining Street): Effortlessly pull out (penetration)

WM NOT GO: Not pull out street

IM GO (Inspection Street): Effortlessly pull out through (penetration)

IM NOT GO: pull out not on the street

In this case, the judgment is divided between the conventional JIS and the current JIS (ISO).

It is necessary to judge the gauge and its standard according to the instruction accuracy.
