姿勢公差 平行度 The axis to which the tolerance refers must lie within a cylinder of diameter 0.03 parallel to the reference axis A.
直角度 The axis of the cylinder to which the tolerance relates must lie between two parallel planes perpendicular to the reference surface with a separation of 0.1.

位置公差 位置度 The axis of the hole must lie within a cylinder of diameter 0.08, whose axis in relation to the surfaces A and B (the reference surfaces) is in the theoretically exact location.
同軸度 The axis of the cylinder associated with the tolerance limits must lie within a cylinder of diameter 0.08 coaxial with the reference axis AB.
対称度 The midplane of the groove must lie between two parallel planes with a separation of 0.08, which are symmetrically placed in relation to the midplane of the reference element A.

振れ公差 円周振れ(半径方向) During one rotation about the reference axis AB, the radial runout must not exceed 0.1 in any measuring plane.
円周振れ(軸方向) During one rotation about the reference axis D, the axial runout must not exceed 0.1 in any measuring position.
全振れ(円周方向) During several rotations about the reference axis AB and on axial displacement between the workpiece and the measuring device, all points on the surface of the element to which the tolerance relates must lie within the overall true running tolerance of t = 0.1. The displacement must be carried out along a line that has the theoretically exact form and is correctly located relative to the reference axis.
全振れ(軸方向) During several rotations about the reference axis D and on radial displacement between the workpiece and the measuring device, all points on the surface of the element to which the tolerance relates must lie within the overall flat running tolerance of t = 0.1. During the displacement, either the measuring device or the workpiece must be moved along a line that has the theoretically exact form and is correctly located relative to the reference axis.
