本试验方法建立了使用塞规评估轴承内衬内径尺寸一致性的标准程序。本试验方法涵盖的轴承包括套筒轴承和内孔球面轴承。注意，这种方法没有给出真实圆柱度的指示。

This test method establishes a standard procedure for using plug gages to evaluate dimensional conformance of lined inside diameters of bearings. Bearings covered by this test method include sleeve bearings and lined bore spherical bearings. Note that this method gives no indication of true cylindricity.
