8、 published in 1965 by changing partially a part of its technical contents and including the items not included in the corresponding International Standard (inspection, designation and marking of products) as the Japanese Industrial Standard. 1 Scope This Japanese Industrial Standard specifies the di
9、al gauges of 0.01 mm, 0.002 mm and 0.001 mm in scale interval and 100 times, 500 times and 700 times or more in magnification (hereafter referred to as “dial gauge”). This applies to the dial gauges of 60 mm or under in outer frame and 10 mm or under in measuring range in the case of 0.01 mm and 0.0
10、02 mm in scale interval and 5 mm or under in measuring range in the case of 0.001 mm in scale internai. 2 Normative reference The following standards contain provisions which, through refer- ence in this Standard, constitute provisions of this Standard.

Remarks : It is called instrumenta1 error as well. maximum permissible error of indication Value of limit to which indication error is permit ted. retrace error The maximum value of the differences of indications for the same measuring quantity when the plunger enters and goes out (Att
