This standard specifies the terms and definitions、 tolerances、 requirements、 inspection、 marking、 and packaging of smooth * limit gauges. This standard applies to smooth * limit gauges with basic dimensions of holes and shafts up to 500 mm and tolerance levels IT6 to IT16. The smooth * limit gauge (hereinafter referred to as the "gauge") specified in this standard is applicable to the inspection of the basic dimensions of holes and shafts specified in GB/T 1800.1-1997 to GB/T 1800.4-1999K * Limits and Fits. 2 Normative References: The clauses in the following documents become the clauses of this standard through the reference surface of this standard. For dated reference documents、 all subsequent modification orders (excluding the content of errors) or revised versions do not apply to this standard. However、 parties who have reached agreements based on this standard are encouraged to study whether new versions of these documents can be used. For undated references、 the latest version of * applies to this standard.

The terms and definitions determined in GB/T 1800.1-1997 to GB/T 1800.4-1999、 as well as the following terms and definitions、 apply to this standard. 3.1 Smooth * Limit Gauge plain limit gauge has a standard measuring surface with the following holes or shafts with * large * limit dimensions and * small * limit dimensions as nominal dimensions、 A non scribed length measuring instrument that can reflect and control the boundary conditions of the inspected hole or shaft. 3.2 Plug gauge is a smooth * limit gauge used for hole diameter inspection、 with a measuring surface of an outer cylindrical surface. Among them、 the diameter of the cylinder with the inspected aperture * small * limited size is the through gauge for the hole、 and the diameter with the inspected aperture * large * limited size is the stop gauge for the hole. 3.3 Ring gauge is a smooth * limit gauge used for shaft diameter inspection、 with the measuring surface being the inner ring surface. Among them、 the diameter of the circular ring with the inspected shaft diameter * large * limited size is the shaft through gauge、 and the diameter with the inspected shaft diameter * small * limited size is the shaft stop gauge
